Question

我想通过表单发布方法发送邮件，但是我得到了

HTTP状态500？服务器内部错误

执行：javax.servlet.ServletException：Servlet执行引发异常        org.apache.tomcat.websocket.server.WsFilter.doFilter（WsFilter.java:53）

注意：我已经安装了库：javax.mail.jar和activation.jar

在我的Mail.jsp页面上

<form action="ServlateMail" method="post">
    To:<input type="text" name="to"  /><br/>
    Subject:<input type="text" name="subject"  /><br/>
    Message:<input type="text" name="message"  /><br/>
    Your Email id:<input type="text" name="user" ><br/>
    Password<;input type="password" name="pass"   /><br/>
    <input type="submit" value="send" />
</form>

在我的ServlateMail中：

package controller;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import utils.Sendmail;


public class ServletMail extends HttpServlet {
  @Override
  protected void doPost(HttpServletRequest request, HttpServletResponse 
  response)
        throws ServletException, IOException {
    response.setContentType("text/html;charset-UTF-8");
    PrintWriter out = response.getWriter();

    String to = request.getParameter("to");
    String subject = request.getParameter("subject");
    String message =  request.getParameter("message");
    String user = request.getParameter("user");
    String pass = request.getParameter("pass");
    Sendmail.sendmailer(to,subject, message, user, pass);
    System.out.println("Mail send successfully");
}   
}

在我的Java课中：

package utils;
import java.io.*;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class Sendmail 
  { 
  public static void sendmailer(String to, String sub, 
                     String msg, final String user,final String pass)
  { 
 Properties props = new Properties();
 props.put("mail.smtp.host", "smtp.gmail.com");
 props.put("mail.smtp.port", "587");        
 props.put("mail.smtp.auth", "true");
 props.put("mail.smtp.starttls.enable", "true");

Session session = Session.getInstance(props,new javax.mail.Authenticator()
{
  protected PasswordAuthentication getPasswordAuthentication() 
  {
     return new PasswordAuthentication(user,pass);
  }
}); 
 try
  {

   MimeMessage message = new MimeMessage(session);
   message.setFrom(new InternetAddress(user));
   message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
   message.setSubject(sub);
   System.out.print("testing");
   message.setText(msg);
   Transport.send(message);


   }
   catch(Exception e)
   {
     e.printStackTrace();
   }
   }  
 }
