JavaMail问题,望解决,在线等,急!!!!!!!!

[zhangleibbq]

我的发邮件的代码:
package classes;

/**用JavaMail发送邮件的类*/
import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
import java.util.Date;
import java.lang.*;
import java.io.*;
import java.net.*;
import javax.activation.DataHandler;


public class MailSender
{
private MailSender()
{
}
/**发送邮件的方法*/
public void sendMail(String toadd,String subject,String text)
{
try{
InternetAddress fromaddress = new InternetAddress("[e-mail]");
String fromsmtp = "smtp.sina.com.cn";
InternetAddress toaddress = new InternetAddress(toadd);
SmtpAuthenticator st = new SmtpAuthenticator();
Properties pt = new Properties();
pt.put("mail.transport.protocol", "smtp");
pt.put("mail.smtp.auth","true");
pt.put("mail.smtp.host",fromsmtp);
Session session = Session.getInstance(pt,st);
MimeMessage msg = new MimeMessage(session);
msg.setFrom(fromaddress);
msg.setRecipient(Message.RecipientType.TO,toaddress);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setContent(text,"text/html;charset=gb2312");
msg.setText(text);
msg.saveChanges();
Transport.send(msg);
}catch(Exception e){System.out.println("Error: "+e.getMessage());return;}
System.out.println("Send mail successfully.");
}
/**到服务器进行验证的类*/
class SmtpAuthenticator extends javax.mail.Authenticator
{
//SMTP服务器身份验证
protected javax.mail.PasswordAuthentication getPasswordAuthentication()
{
return new javax.mail.PasswordAuthentication("zlbbq47054370","5626154");
}
}
public static void main(String args[])
{
MailSender ms = new MailSender();
ms.sendMail("[e-mail]","Test","http://www.sina.com");
}
}





编译通过,但是发邮件的时候会出现异常:javax.activation.UnsupportedDataTypeException: no object DCH for MIME type text/html,请指教哪步错了.

[leshui]

有可能是
换一个试试
163的就可以

[zhangleibbq]

我找到错误原因了,是DCH(DataContentHandler)的原因,Transport在发送邮件的时候,先要将其转换成MIME类型,它将调用javax.mail.activation.CommandMap,具体代码如下:
javax.mail.activation.CommandMap cmp = javax.mail.activation.CommandMap.getDefaultCommandMap();
DataConentHandler DCH = cmp.createDataContentHandler(contenttype);//contenttype="text/palin","text/html","multipart/*"...
if(DCH==null)
{
throw new UnSupprotedDataTypeException("no object DCH for MIME type"+contenttype);
}

CommandMap会在META-INF目录下找一个叫mailcap的文件,我的系统没有找到,所以DCH对角为空,呵呵呵.还是谢谢各位.

下面是我很早已前写的
编译通过
运行正常

leshui(大象无形)(有物混成,先天地生),有问题,代码还是一样的代码,我发不出去,
Exception 还是一样的Exception,多了一点:boundary="----=_Part_0_31XXXXXXXXXXXXXXX",
多谢指出是哪个地方的原因.

[leshui]

应该没问题的
是不是有的包没有
要两个包 javamail和jaf

[littlecong]

发html类型的邮件，请参考javaMail自带的一个例子，具体我记不清了

不可能没有包的,如果没有包的话,首先,编译就不能通过.这是什么情况,会不会是smtp服务器的问题?
