Question

I’m trying to configure servlet to send a message to Gmail, but I’m getting waiting for reply message down my browser window.

Here’s the servlet code:

import javax.mail.*;
import javax.mail.internet.*;
import javax.servlet.http.*;
import javax.servlet.*;
import java.io.*;


public class JavaMailServlet extends HttpServlet 
{

public void doGet(HttpServletRequest request,HttpServletResponse response)
{

    try{

        String userName=request.getParameter("p1");
        String password=request.getParameter("p2");;

        Properties props=new Properties();
        props.put("mail.smtp.host","smtp.gmail.com");
        props.put("mail.smtp.port",465);


        Session ses=Session.getInstance(props,null);
        Message msg=new MimeMessage(ses);
        msg.setFrom(new InternetAddress(request.getRequestURI()));
        msg.addRecipient(Message.RecipientType.TO,new InternetAddress("[e-mail]"));
        msg.setSubject("Hello");
        msg.setText("What's up?");
        Transport.send(msg);
        response.getWriter().println("Message sent");
    }

    catch(Exception e)
    {
        System.out.println(e);
    }

}
}

What do I’ve to do to make the connection?

Answer 1

Well, you haven’t set up any authentication as far as I can tell. You’ve grabbed the username and the password from the request (I do hope this is over HTTPS) but you haven’t used it anywhere.

I strongly recommend that you try to get this working in a console app which will be much easier to debug than a servlet, then put it into a servlet environment.
