Tutorial tips Should I take this tutorial? Looking to incorporate mail facilities into your platform-independent Java solutions? Look no further than the JavaMail API, which offers a protocol-independent model for working with IMAP, POP, SMTP, MIME, and all those other Internet-related messaging protocols. With the help of the JavaBeans Activation Framework (JAF), your applications can now be mail-enabled through the JavaMail API. Concepts After completing this module you will understand the: * Basics of the Internet mail protocols SMTP, POP3, IMAP, and MIME * Architecture of the JavaMail framework * Connections between the JavaMail API and the JavaBeans Activation Framework Objectives By the end of this module you will be able to: * Send and read mail using the JavaMail API * Deal with sending and receiving attachments * Work with HTML messages * Use search terms to search for messages Prerequisites Instructions on how to download and install the JavaMail API are contained in the course. In addition, you will need a development environment such as the JDK 1.1.6+ or the Java 2 Platform, Standard Edition (J2SE) 1.2.x or 1.3.x. A general familiarity with object-oriented programming concepts and the Java programming language is necessary. The Java language essentials tutorial can help. copyright 1996-2000 Magelang Institute dba jGuru Contact jGuru has been dedicated to promoting the growth of the Java technology community through evangelism, education, and software since 1995.

Fundamentals of the JavaMail API Page 2 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Section 2. Introducing the JavaMail API What is the JavaMail API? The JavaMail API is an optional package (standard extension) for reading, composing, and sending electronic messages. You use the package to create Mail User Agent (MUA) type programs, similar to Eudora, pine, and Microsoft Outlook. The API's main purpose is not for transporting, delivering, and forwarding messages; this is the purview of applications such as sendmail and other Mail Transfer Agent (MTA) type programs. MUA-type programs let users read and write e-mail, whereas MUAs rely on MTAs to handle the actual delivery. The JavaMail API is designed to provide protocol-independent access for sending and receiving messages by dividing the API into two parts: * The first part of the API is the focus of this course --basically, how to send and receive messages independent of the provider/protocol. * The second part speaks the protocol-specific languages, like SMTP, POP, IMAP, and NNTP. With the JavaMail API, in order to communicate with a server, you need a provider for a protocol. The creation of protocol-specific providers is not covered in this course because Sun provides a sufficient set for free. Fundamentals of the JavaMail API Page 3 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Section 3. Reviewing related protocols Introduction Before looking into the JavaMail API specifics, let's step back and take a look at the protocols used with the API. There are basically four that you'll come to know and love: * SMTP * POP * IMAP * MIME You will also run across NNTP and some others. Understanding the basics of all the protocols will help you understand how to use the JavaMail API. While the API is designed to be protocol agnostic, you can't overcome the limitations of the underlying protocols. If a capability isn't supported by a chosen protocol, the JavaMail API doesn't magically add the capability on top of it. (As you'll soon see, this can be a problem when working with POP.) SMTP The Simple Mail Transfer Protocol (SMTP) is defined by RFC 821 . It defines the mechanism for delivery of e-mail. In the context of the JavaMail API, your JavaMail-based program will communicate with your company or Internet Service Provider's (ISP's) SMTP server. That SMTP server will relay the message on to the SMTP server of the recipient(s) to eventually be acquired by the user(s) through POP or IMAP. This does not require your SMTP server to be an open relay, as authentication is supported, but it is your responsibility to ensure the SMTP server is configured properly. There is nothing in the JavaMail API for tasks like configuring a server to relay messages or to add and remove e-mail accounts. POP POP stands for Post Office Protocol. Currently in version 3, also known as POP3, RFC 1939 defines this protocol. POP is the mechanism most people on the Internet use to get their mail. It defines support for a single mailbox for each user. That is all it does, and that is also the source of a lot of confusion. Much of what people are familiar with when using POP, like the ability to see how many new mail messages they have, are not supported by POP at all. These capabilities are built into programs like Eudora or Microsoft Outlook, which remember things like the last mail received and calculate how many are new for you. So, when using the JavaMail API, if you want this type of information, you have to calculate it yourself. IMAP IMAP is a more advanced protocol for receiving messages. Defined in RFC 2060 , IMAP stands for Internet Message Access Protocol, and is currently in version 4, also known as IMAP4. When using IMAP, your mail server must support the protocol. You can't just change your program to use IMAP instead of POP and expect everything in IMAP to be supported. Assuming your mail server supports IMAP, your JavaMail-based program can take Fundamentals of the JavaMail API Page 4 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks advantage of users having multiple folders on the server and these folders can be shared by multiple users. Due to the more advanced capabilities, you might think IMAP would be used by everyone. It isn't. It places a much heavier burden on the mail server, requiring the server to receive the new messages, deliver them to users when requested, and maintain them in multiple folders for each user. While this does centralize backups, as users' long-term mail folders get larger and larger, everyone suffers when disk space is exhausted. With POP, saved messages get offloaded from the mail server. MIME MIME stands for Multipurpose Internet Mail Extensions. It is not a mail transfer protocol. Instead, it defines the content of what is transferred: the format of the messages, attachments, and so on. There are many different documents that take effect here: RFC 822 , RFC 2045 , RFC 2046 , and RFC 2047 . As a user of the JavaMail API, you usually don't need to worry about these formats. However, these formats do exist and are used by your programs. NNTP and others Because of the split of the JavaMail API between provider and everything else, you can easily add support for additional protocols. Sun maintains a list of third-party providers that take advantage of protocols for which Sun does not provide out-of-the-box support. You'll find support for NNTP (Network News Transport Protocol) [newsgroups], S/MIME (Secure Multipurpose Internet Mail Extensions), and more. Fundamentals of the JavaMail API Page 5 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Section 4. Installing JavaMail Introduction There are two versions of the JavaMail API commonly used today: 1.2 and 1.1.3. All the examples in this course will work with both. While 1.2 is the latest, 1.1.3 is the version included with the 1.2.1 version of the Java 2 Platform, Enterprise Edition (J2EE), so it is still commonly used. The version of the JavaMail API you want to use affects what you download and install. All will work with JDK 1.1.6+, Java 2 Platform, Standard Edition (J2SE) version 1.2.x, and J2SE version 1.3.x. Note: After installing Sun's JavaMail implementation, you can find many example programs in the demo directory. Installing JavaMail 1.2 To use the JavaMail 1.2 API, download the JavaMail 1.2 implementation, unbundle the javamail-1_2.zip file, and add the mail.jar file to your CLASSPATH. The 1.2 implementation comes with an SMTP, IMAP4, and POP3 provider besides the core classes. After installing JavaMail 1.2, install the JavaBeans Activation Framework. Installing JavaMail 1.1.3 To use the JavaMail 1.1.3 API, download the JavaMail 1.1.3 implementation, unbundle the javamail1_1_3.zip file, and add the mail.jar file to your CLASSPATH. The 1.1.3 implementation comes with an SMTP and IMAP4 provider, besides the core classes. If you want to access a POP server with JavaMail 1.1.3, download and install a POP3 provider. Sun has one available separate from the JavaMail implementation. After downloading and unbundling pop31_1_1.zip, add pop3.jar to your CLASSPATH, too. After installing JavaMail 1.1.3, install the JavaBeans Activation Framework. Installing the JavaBeans Activation Framework All versions of the JavaMail API require the JavaBeans Activation Framework. The framework adds support for typing arbitrary blocks of data and handling it accordingly. This doesn't sound like much, but it is your basic MIME-type support found in many browsers and mail tools today. After downloading the framework, unbundle the jaf1_0_1.zip file, and add the activation.jar file to your CLASSPATH. For JavaMail 1.2 users, you should now have added mail.jar and activation.jar to your CLASSPATH. For JavaMail 1.1.3 users, you should now have added mail.jar, pop3.jar, and activation.jar to your CLASSPATH. If you have no plans of using POP3, you don't Fundamentals of the JavaMail API Page 6 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks need to add pop3.jar to your CLASSPATH. If you don't want to change the CLASSPATH environment variable, copy the jar files to your lib/ext directory under the Java Runtime Environment (JRE) directory. For instance, for the J2SE 1.3 release, the default directory would be C:\jdk1.3\jre\lib\ext on a Windows platform. Using JavaMail with the Java 2 Enterprise Edition If you use J2EE, there is nothing special you have to do to use the basic JavaMail API; it comes with the J2EE classes. Just make sure the j2ee.jar file is in your CLASSPATH and you're all set. For J2EE 1.2.1, the POP3 provider comes separately, so download and follow the steps to include the POP3 provider as shown in the previous section "Installing JavaMail 1.1.3." J2EE 1.3 users get the POP3 provider with J2EE so do not require the separate installation. Neither installation requires you to install the JavaBeans Activation Framework. Exercise Exercise 1. How to set up a JavaMail environment on page 22 Fundamentals of the JavaMail API Page 7 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Section 5. Reviewing the core classes Introduction Before taking a how-to approach at looking at the JavaMail classes in depth, this section walks you through the core classes that make up the API: Session, Message, Address, Authenticator, Transport, Store, and Folder. All these classes are found in the top-level package for the JavaMail API, javax.mail, though you'll frequently find yourself using subclasses found in the javax.mail.internet package. Session The Session class defines a basic mail session. It is through this session that everything else works. The Session object takes advantage of a java.util.Properties object to get information like mail server, username, password, and other information that can be shared across your entire application. The constructors for the class are private. You can get a single default session that can be shared with the getDefaultInstance() method: Properties props = new Properties(); // fill props with any information Session session = Session.getDefaultInstance(props, null); Or, you can create a unique session with getInstance(): Properties props = new Properties(); // fill props with any information Session session = Session.getDefaultInstance(props, null); In both cases, the null argument is an Authenticator object that is not being used at this time. In most cases, it is sufficient to use the shared session, even if working with mail sessions for multiple user mailboxes. You can add the username and password combination in at a later step in the communication process, keeping everything separate. Message Once you have your Session object, it is time to move on to creating the message to send. This is done with a type of Message . Because Message is an abstract class, you must work with a subclass, in most cases javax.mail.internet.MimeMessage .A MimeMessage is an e-mail message that understands MIME types and headers, as defined in the different RFCs. Message headers are restricted to US-ASCII characters only, though non-ASCII characters can be encoded in certain header fields. To create a Message, pass along the Session object to the MimeMessage constructor: MimeMessage message = new MimeMessage(session); Fundamentals of the JavaMail API Page 8 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Note: There are other constructors, like for creating messages from RFC822-formatted input streams. Once you have your message, you can set its parts, as Message implements the Part interface (with MimeMessage implementing MimePart ). The basic mechanism to set the content is the setContent() method, with arguments for the content and the mime type: message.setContent("Hello", "text/plain"); If, however, you know you are working with a MimeMessage and your message is plain text, you can use its setText() method, which only requires the actual content, defaulting to the MIME type of text/plain: message.setText("Hello"); For plain text messages, the latter form is the preferred mechanism to set the content. For sending other kinds of messages, like HTML messages, use the former. For setting the subject, use the setSubject() method: message.setSubject("First"); Address Once you've created the Session and the Message, as well as filled the message with content, it is time to address your letter with an Address . Like Message, Address is an abstract class. You use the javax.mail.internet.InternetAddress class. To create an address with just the e-mail address, pass the e-mail address to the constructor: Address address = new InternetAddress("president@whitehouse.gov"); If you want a name to appear next to the e-mail address, you can pass that along to the constructor, too: Address address = new InternetAddress("president@whitehouse.gov", "George Bush"); You will need to create address objects for the message's from field as well as the to field. Unless your mail server prevents you, there is nothing stopping you from sending a message that appears to be from anyone. Once you've created the addresses, you connect them to a message in one of two ways. For identifying the sender, you use the setFrom() and setReplyTo() methods. message.setFrom(address) If your message needs to show multiple from addresses, use the addFrom() method: Fundamentals of the JavaMail API Page 9 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Address address[] = ...; message.addFrom(address); For identifying the message recipients, you use the addRecipient() method. This method requires a Message.RecipientType besides the address. message.addRecipient(type, address) The three predefined types of address are: * Message.RecipientType.TO * Message.RecipientType.CC * Message.RecipientType.BCC So, if the message was to go to the vice president, sending a carbon copy to the first lady, the following would be appropriate: Address toAddress = new InternetAddress("vice.president@whitehouse.gov"); Address ccAddress = new InternetAddress("first.lady@whitehouse.gov"); message.addRecipient(Message.RecipientType.TO, toAddress); message.addRecipient(Message.RecipientType.CC, ccAddress); The JavaMail API provides no mechanism to check for the validity of an e-mail address. While you can program in support to scan for valid characters (as defined by RFC 822) or verify the MX (mail exchange) record yourself, these are all beyond the scope of the JavaMail API. Authenticator Like the java.net classes, the JavaMail API can take advantage of an Authenticator to access protected resources via a username and password. For the JavaMail API, that resource is the mail server. The JavaMail Authenticator is found in the javax.mail package and is different from the java.net class of the same name. The two don't share the same Authenticator as the JavaMail API works with Java 1.1, which didn't have the java.net variety. To use the Authenticator, you subclass the abstract class and return a PasswordAuthentication instance from the getPasswordAuthentication() method. You must register the Authenticator with the session when created. Then, your Authenticator will be notified when authentication is necessary. You could pop up a window or read the username and password from a configuration file (though if not encrypted is not secure), returning them to the caller as a PasswordAuthentication object. Properties props = new Properties(); // fill props with any information Authenticator auth = new MyAuthenticator(); Session session = Session.getDefaultInstance(props, auth); Transport The final part of sending a message is to use the Transport class. This class speaks the Fundamentals of the JavaMail API Page 10 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks protocol-specific language for sending the message (usually SMTP). It's an abstract class and works something like Session. You can use the default version of the class by just calling the static send() method: Transport.send(message); Or, you can get a specific instance from the session for your protocol, pass along the username and password (blank if unnecessary), send the message, and close the connection: message.saveChanges(); // implicit with send() Transport transport = session.getTransport("smtp"); transport.connect(host, username, password); transport.sendMessage(message, message.getAllRecipients()); transport.close(); This latter way is best when you need to send multiple messages, as it will keep the connection with the mail server active between messages. The basic send() mechanism makes a separate connection to the server for each method call. Note: To watch the mail commands go by to the mail server, set the debug flag with session.setDebug(true). Store and folder Getting messages starts similarly to sending messages with a Session. However, after getting the session, you connect to a Store , quite possibly with a username and password or Authenticator. Like Transport, you tell the Store what protocol to use: // Store store = session.getStore("imap"); Store store = session.getStore("pop3"); store.connect(host, username, password); After connecting to the Store, you can then get a Folder , which must be opened before you can read messages from it: Folder folder = store.getFolder("INBOX"); folder.open(Folder.READ_ONLY); Message message[] = folder.getMessages(); For POP3, the only folder available is the INBOX. If you are using IMAP, you can have other folders available. Note: Sun's providers are meant to be smart. While Message message[] = folder.getMessages(); might look like a slow operation reading every message from the server, only when you actually need to get a part of the message is the message content retrieved. Once you have a Message to read, you can get its content with getContent() or write its content to a stream with writeTo(). The getContent() method only gets the message content, while writeTo() output includes headers. Fundamentals of the JavaMail API Page 11 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks System.out.println(((MimeMessage)message).getContent()); Once you're done reading mail, close the connection to the folder and store. folder.close(aBoolean); store.close(); The boolean passed to the close() method of folder states whether or not to update the folder by removing deleted messages. Moving on Essentially, understanding how to use these seven classes is all you need for nearly everything with the JavaMail API. Most of the other capabilities of the JavaMail API build off these seven classes to do something a little different or in a particular way, like if the content is an attachment. Certain tasks, like searching, are isolated and are discussed later. Fundamentals of the JavaMail API Page 12 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Section 6. Using the JavaMail API Introduction You've seen how to work with the core parts of the JavaMail API. In the following sections you'll find a how-to approach for connecting the pieces to do specific tasks. Sending messages Sending an e-mail message involves getting a session, creating and filling a message, and sending it. You can specify your SMTP server by setting the mail.smtp.host property for the Properties object passed when getting the Session: String host = ...; String from = ...; String to = ...; // Get system properties Properties props = System.getProperties(); // Setup mail server props.put("mail.smtp.host", host); // Get session Session session = Session.getDefaultInstance(props, null); // Define message MimeMessage message = new MimeMessage(session); message.setFrom(new InternetAddress(from)); message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); message.setSubject("Hello JavaMail"); message.setText("Welcome to JavaMail"); // Send message Transport.send(message); You should place the code in a try-catch block, as setting up the message and sending it can throw exceptions. Exercise: Exercise 2. How to send your first message on page 23 Fetching messages For reading mail, you get a session, get and connect to an appropriate store for your mailbox, open the appropriate folder, and get your messages. Also, don't forget to close the connection when done. String host = ...; String username = ...; String password = ...; // Create empty properties Properties props = new Properties(); // Get session Session session = Session.getDefaultInstance(props, null); Fundamentals of the JavaMail API Page 13 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks // Get the store Store store = session.getStore("pop3"); store.connect(host, username, password); // Get folder Folder folder = store.getFolder("INBOX"); folder.open(Folder.READ_ONLY); // Get directory Message message[] = folder.getMessages(); for (int i=0, n=message.length; iJavaMail API Page 14 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Just because a flag exists doesn't mean the flag is supported by all mail servers or providers. For instance, except for deleting messages, the POP protocol supports none of them. Checking for new mail is not a POP task but a task built into mail clients. To find out what flags are supported, ask the folder with getPermanentFlags(). To delete messages, you set the message's DELETED flag: message.setFlag(Flags.Flag.DELETED, true); Open up the folder in READ_WRITE mode first though: folder.open(Folder.READ_WRITE); Then, when you are done processing all messages, close the folder, passing in a true value to expunge the deleted messages. folder.close(true); There is an expunge() method of Folder that can be used to delete the messages. However, it doesn't work for Sun's POP3 provider. Other providers may or may not implement the capabilities. It will more than likely be implemented for IMAP providers. Because POP only supports single access to the mailbox, you have to close the folder to delete the messages with Sun's provider. To unset a flag, just pass false to the setFlag() method. To see if a flag is set, check it with isSet(). Authenticating yourself You learned that you can use an Authenticator to prompt for username and password when needed, instead of passing them in as strings. Here you'll actually see how to more fully use authentication. Instead of connecting to the Store with the host, username, and password, you configure the Properties to have the host, and tell the Session about your custom Authenticator instance, as shown here: // Setup properties Properties props = System.getProperties(); props.put("mail.pop3.host", host); // Setup authentication, get session Authenticator auth = new PopupAuthenticator(); Session session = Session.getDefaultInstance(props, auth); // Get the store Store store = session.getStore("pop3"); store.connect(); You then subclass Authenticator and return a PasswordAuthentication object from the getPasswordAuthentication() method. The following is one such implementation, with a single field for both. (This isn't a Project Swing tutorial; just enter the two parts in the one field, separated by a comma.) Fundamentals of the JavaMail API Page 15 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks import javax.mail.*; import javax.swing.*; import java.util.*; public class PopupAuthenticator extends Authenticator { public PasswordAuthentication getPasswordAuthentication() { String username, password; String result = JOptionPane.showInputDialog( "Enter 'username,password'"); StringTokenizer st = new StringTokenizer(result, ","); username = st.nextToken(); password = st.nextToken(); return new PasswordAuthentication(username, password); } } Because the PopupAuthenticator relies on Swing, it will start up the event-handling thread for AWT. This basically requires you to add a call to System.exit() in your code to stop the program. Replying to messages The Message class includes a reply() method to configure a new Message with the proper recipient and subject, adding "Re: " if not already there. This does not add any content to the message, only copying the from or reply-to header to the new recipient. The method takes a boolean parameter indicating whether to reply to only the sender (false) or reply to all (true). MimeMessage reply = (MimeMessage)message.reply(false); reply.setFrom(new InternetAddress("president@whitehouse.gov")); reply.setText("Thanks"); Transport.send(reply); To configure the reply-to address when sending a message, use the setReplyTo() method. Exercise: Exercise 4. How to reply to mail on page 27 Forwarding messages Forwarding messages is a little more involved. There is no single method to call, and you build up the message to forward by working with the parts that make up a message. A mail message can be made up of multiple parts. Each part is a BodyPart , or more specifically, a MimeBodyPart when working with MIME messages. The different body parts get combined into a container called Multipart or, again, more specifically a MimeMultipart . To forward a message, you create one part for the text of your message and a second part with the message to forward, and combine the two into a multipart. Then you add the multipart to a properly addressed message and send it. That's essentially it. To copy the content from one message to another, just copy over its Fundamentals of the JavaMail API Page 16 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks DataHandler , a class from the JavaBeans Activation Framework. // Create the message to forward Message forward = new MimeMessage(session); // Fill in header forward.setSubject("Fwd: " + message.getSubject()); forward.setFrom(new InternetAddress(from)); forward.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // Create your new message part BodyPart messageBodyPart = new MimeBodyPart(); messageBodyPart.setText( "Here you go with the original message:\n\n"); // Create a multi-part to combine the parts Multipart multipart = new MimeMultipart(); multipart.addBodyPart(messageBodyPart); // Create and fill part for the forwarded content messageBodyPart = new MimeBodyPart(); messageBodyPart.setDataHandler(message.getDataHandler()); // Add part to multi part multipart.addBodyPart(messageBodyPart); // Associate multi-part with message forward.setContent(multipart); // Send message Transport.send(forward); Working with attachments Attachments are resources associated with a mail message, usually kept outside of the message like a text file, spreadsheet, or image. As with common mail programs like Eudora and pine, you can attach resources to your mail message with the JavaMail API and get those attachments when you receive the message. Sending attachments: Sending attachments is quite like forwarding messages. You build up the parts to make the complete message. After the first part, your message text, you add other parts where the DataHandler for each is your attachment, instead of the shared handler in the case of a forwarded message. If you are reading the attachment from a file, your attachment data source is a FileDataSource . Reading from a URL, it is a URLDataSource . Once you have your DataSource, just pass it on to the DataHandler constructor, before finally attaching it to the BodyPart with setDataHandler(). Assuming you want to retain the original filename for the attachment, the last thing to do is to set the filename associated with the attachment with the setFileName() method of BodyPart. All this is shown here: // Define message Message message = new MimeMessage(session); message.setFrom(new InternetAddress(from)); message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); message.setSubject("Hello JavaMail Attachment"); // Create the message part BodyPart messageBodyPart = new MimeBodyPart(); // Fill the message messageBodyPart.setText("Pardon Ideas"); Fundamentals of the JavaMail API Page 17 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Multipart multipart = new MimeMultipart(); multipart.addBodyPart(messageBodyPart); // Part two is attachment messageBodyPart = new MimeBodyPart(); DataSource source = new FileDataSource(filename); messageBodyPart.setDataHandler(new DataHandler(source)); messageBodyPart.setFileName(filename); multipart.addBodyPart(messageBodyPart); // Put parts in message message.setContent(multipart); // Send the message Transport.send(message); When including attachments with your messages, if your program is a servlet, your users must upload the attachment besides telling you where to send the message. Uploading each file can be handled with a form encoding type of multipart/form-data. Note: Message size is limited by your SMTP server, not the JavaMail API. If you run into problems, consider increasing the Java heap size by setting the ms and mx parameters. Exercise: Exercise 5. How to send attachments on page 28 Getting attachments: Getting attachments out of your messages is a little more involved then sending them because MIME has no simple notion of attachments. The content of your message is a Multipart object when it has attachments. You then need to process each Part, to get the main content and the attachment(s). Parts marked with a disposition of Part.ATTACHMENT from part.getDisposition() are clearly attachments. However, attachments can also come across with no disposition (and a non-text MIME type) or a disposition of Part.INLINE. When the disposition is either Part.ATTACHMENT or Part.INLINE, you can save off the content for that message part. Just get the original filename with getFileName() and the input stream with getInputStream(). Multipart mp = (Multipart)message.getContent(); for (int i=0, n=multipart.getCount(); iJavaMail API Page 18 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks for (int i=0; file.exists(); i++) { file = new File(filename+i); } The code above covers the simplest case where message parts are flagged appropriately. To cover all cases, handle when the disposition is null and get the MIME type of the part to handle accordingly. if (disposition == null) { // Check if plain MimeBodyPart mbp = (MimeBodyPart)part; if (mbp.isMimeType("text/plain")) { // Handle plain } else { // Special non-attachment cases here of image/gif, text/html, ... } ... } Processing HTML messages Sending HTML-based messages can be a little more work than sending plain text message, though it doesn't have to be that much more work. It all depends on your specific requirements. Sending HTML messages: If all you need to do is send the equivalent of an HTML file as the message and let the mail reader worry about fetching any embedded images or related pieces, use the setContent() method of Message, passing along the content as a String and setting the content type to text/html. String htmlText = "

Hello

"; message.setContent(htmlText, "text/html")); On the receiving end, if you fetch the message with the JavaMail API, there is nothing built into the API to display the message as HTML. The JavaMail API only sees it as a stream of bytes. To display the message as HTML, you must either use the Swing JEditorPane or some third-party HTML viewer component. if (message.getContentType().equals("text/html")) { String content = (String)message.getContent(); JFrame frame = new JFrame(); JEditorPane text = new JEditorPane("text/html", content); text.setEditable(false); JScrollPane pane = new JScrollPane(text); frame.getContentPane().add(pane); frame.setSize(300, 300); frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); frame.show(); } Including images with your messages: On the other hand, if you want your HTML content message to be complete, with embedded images included as part of the message, you must treat the image as an attachment and reference the image with a special cid URL, where the cid is a reference to the Content-ID header of the image attachment. The process of embedding an image is quite similar to attaching a file to a message, the only Fundamentals of the JavaMail API Page 19 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks difference is you have to tell the MimeMultipart that the parts are related by setting its subtype in the constructor (or with setSubType()) and set the Content-ID header for the image to a random string which is used as the src for the image in the img tag. The following demonstrates this completely. String file = ...; // Create the message Message message = new MimeMessage(session); // Fill its headers message.setSubject("Embedded Image"); message.setFrom(new InternetAddress(from)); message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // Create your new message part BodyPart messageBodyPart = new MimeBodyPart(); String htmlText = "

Hello

"; messageBodyPart.setContent(htmlText, "text/html"); // Create a related multi-part to combine the parts MimeMultipart multipart = new MimeMultipart("related"); multipart.addBodyPart(messageBodyPart); // Create part for the image messageBodyPart = new MimeBodyPart(); // Fetch the image and associate to part DataSource fds = new FileDataSource(file); messageBodyPart.setDataHandler(new DataHandler(fds)); messageBodyPart.setHeader("Content-ID","memememe"); // Add part to multi-part multipart.addBodyPart(messageBodyPart); // Associate multi-part with message message.setContent(multipart); Exercise: Exercise 6.

Searching with SearchTerm Introduction The JavaMail API includes a filtering mechanism found in the javax.mail.search package to build up a SearchTerm . Once built, you then ask a Folder what messages match, retrieving an array of Message objects: SearchTerm st = ...; Message[] msgs = folder.search(st); There are 22 different classes available to help you build a search term. * AND terms (class AndTerm) * OR terms (class OrTerm) * NOT terms (class NotTerm) * SENT DATE terms (class SentDateTerm) * CONTENT terms (class BodyTerm) * HEADER terms (FromTerm / FromStringTerm, RecipientTerm / RecipientStringTerm, SubjectTerm, etc..) Essentially, you build up a logical expression for matching messages, then search. For instance the following term searches for messages with a (partial) subject string of ADV or a from field of friend@public.com. You might consider periodically running this query and automatically deleting any messages returned. SearchTerm st = new OrTerm( new SubjectTerm("ADV:"), new FromStringTerm("friend@public.com")); Message[] msgs = folder.search(st); Fundamentals of the JavaMail API Page 21 Presented by developerWorks, your source for great tutorials ibm.com/developerWorks Section 8. Exercises About the exercises These exercises are designed to provide help according to your needs. For example, you might simply complete the exercise given the information and the task list in the exercise body; you might want a few hints; or you may want a step-by-step guide to successfully complete a particular exercise. You can use as much or as little help as you need per exercise.

Wrapup In summary The JavaMail API is a Java package used for reading, composing, and sending e-mail messages and their attachments. It lets you build standards-based e-mail clients that employ various Internet mail protocols, including SMTP, POP, IMAP, and MIME, as well as related protocols such as NNTP, S/MIME, and others. The API divides naturally into two parts. The first focuses on sending, receiving, and managing messages independent of the protocol used, whereas the second focuses on specific use of the protocols. The purpose of this tutorial was to show how to use the first part of the API, without attempting to deal with protocol providers. The core JavaMail API consists of seven classes --Session, Message, Address, Authenticator, Transport, Store, and Folder --all of which are found in javax.mail, the top-level package for the JavaMail API. We used these classes to work through a number of common e-mail-related tasks, including sending messages, retrieving messages, deleting messages, authenticating, replying to messages, forwarding messages, managing attachments, processing HTML-based messages, and searching or filtering mail lists. Finally, we provided a number of step-by-step exercises to help illustrate the concepts presented. Hopefully, this will help you add e-mail functionality to your platform-independent Java applications. Resources You can do much more with the JavaMail API than what's found here. The lessons and exercises found here can be supplemented by the following resources: * Download the JavaMail 1.2 API from the JavaMail API home page . * The JavaBeans Activation Framework is required for versions 1.2 and 1.1.3 of the JavaMail API. * The JavaMail-interest mailing list is a Sun-hosted discussion forum for developers. * Sun's JavaMail FAQ addresses the use of JavaMail in applets and servlets, as well as prototol-specific questions. * Tutorial author John Zukowski maintains jGuru's JavaMail FAQ . * Want to see how others are using JavaMail? Check out Sun's list of third-party products. * If you want more detail about JavaMail, read Rick Grehan's "How JavaMail keeps it simple" (Lotus Developer Network, June 2000). * Benoit Marchal shows how to use Java and XML to produce plain text and HTML newsletters in this two-part series, "Managing e-zines with JavaMail and XSLT" Part 1 (developerWorks, March 2001) and Part 2 (developerWorks, April 2001). * "Linking Applications with E-mail" (Lotus Developer Network, May 2000) discusses how groupware can facilitate communication, collaboration, and coordination among applications.
