一个发送MAIL的BEAN

package homepage;

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

*/

public class SmtpAuthenticator extends javax.mail.Authenticator{
//SMTP身份验证
protected javax.mail.PasswordAuthentication getPasswordAuthentication()
{
return new javax.mail.PasswordAuthentication("coolwen.com","password");
}
}

package homepage;

import java.io.IOException;
import java.io.OutputStream;

/**

public class SendMail{

private String smtp="smtp.163.com",from="coolwen.com@163.com";
//发送一个邮件
public boolean SendMail(String subject,String body,String to,String filename){
try {

SmtpAuthenticator sa=new SmtpAuthenticator();
Properties props=System.getProperties();
props.put("mail.smtp.auth","true");
props.put("mail.smtp.host",smtp);

Session sess=Session.getInstance(props,sa);
sess.setDebug(true);

Message msg = new MimeMessage(sess);
msg.setDataHandler(new DataHandler(body,"text/html; charset=gb2312"));
if(filename.equals("") || filename == null||filename.equals("null"))
{
msg.setFrom(new InternetAddress(from));
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to,false));
msg.setSubject(subject);
}else{
msg.setFrom(new InternetAddress(from));
msg.addRecipient(javax.mail.Message.RecipientType.TO, new InternetAddress(to));
msg.setSubject(subject);
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setText(body);
MimeBodyPart mbp2 = new MimeBodyPart();
//File file=new File(filename);

}
msg.setSentDate(new Date());
//msg.setText(body);
Transport.send(msg);
return true;
} catch (Exception e) {
return false;
}
}
}

在JSP中使用

<%@page contentType="text/html; charset=gb2312" language="java"%>
<jsp:useBean id="send" scope="page" class="homepage.SendMail" />
<%
if(send.SendMail("中国","中国","coolwen.com@163.com","D:\\myGUI.java"))
out.println("ok");
else
out.println("no");
%>
