发送邮件成功的程序，但转到另一台服务器就报错，有会的进，不会的可以看例子，测试下噢，

[wl1985]

测试邮件发送的网址
http://218.30.123.105:8080/jsp/test2
此处发送邮件能成功的例子如上，
注意用户名及密码是填写本服务器的administrator密码暂不公布，大家有兴趣可以在本机发布,源码如下：
服务器环境，支持smtpmail服务，安装了jmail组件,下了两个javamail-1.3.1和javabeans activation framework

然后解压，把mail.jar和activation.jar放到了classpath里。
放在TOMCAT的common\lib目录下:

同样的配置方法我换用另一台服务器上
结果tomcat报如下错误

有大虾给看看噢，肯定是服务器的环境问题！
谢谢了！

我是换了一台服务器去发布这个程序后就不能调用发送邮件的程序了，

[djpsunday]

javax.mail.AuthenticationFailedException服务器SMTP认证失败!
访问的程序不太对，改用下你的邮箱帐号及登陆邮箱的密码访问方式
具体请登陆上http://www.cn-java.com/index_focus.php?kind=22&title=JavaMail
有相关的文章及源码，看看就配OK了！

可能是你换了一台机器不能访问你的mail服务器？

[wl1985]

SmtpAuthenticator.java
---------
package research.logic;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.*;
import javax.mail.internet.*;

public class SmtpAuthenticator extends javax.mail.Authenticator
{
String username; //用户名
String password; //密码
//实例化这个类时设置用户名和密码
public SmtpAuthenticator(String username, String password)
{
this.username = username;
this.password = password;
}

//重载getPasswordAuthentication函数
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(username, password);
}
}

---------
前台JSP文件如下：
mailform.jsp
package research.logic;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.*;
import javax.mail.internet.*;

public class SmtpAuthenticator extends javax.mail.Authenticator
{
String username; //用户名
String password; //密码
//实例化这个类时设置用户名和密码
public SmtpAuthenticator(String username, String password)
{
this.username = username;
this.password = password;
}

//重载getPasswordAuthentication函数
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(username, password);
}
}
