Solution 1

java.lang.NoClassDefFoundError: javax/mail/MessagingException

Add the mail.jar for example in your tomcat lib (/catalina_home/commons/libs/) or your web application file (see web-inf/lib).

Also you might need the activation jar.

For latest javax.mail.jar see https://java.net/projects/javamail/pages/Home

Solution 2

You miss javax.mail-<version>.jar in your classpath. Download it and add it to your classpath. It is possible that you miss also the dependencies of this jar.

I want to send a email from my gmail account to the another mail account using eclipse.I used apache tomcat 7.0.34 as my web server and use port 8080 for apache server(HTTP/1.1) and use JRE 7 as system library and also include mail.jar and activation.jar in Libraries under Java Resources.

In the below my jsp page is given,where the recipient address is entered and submit to the server.

SendMail.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
        <title>Insert title here</title>
    </head>
    <body>
        <form action="ControllerMail">
            Recipient Address : <input type="email" name="to" ><br/><br/>
            <input type="submit" value="Submit"/>
            <input type="hidden" name="pageType" value="sendmail"/>
        </form>
    </body>
</html>

Now, My servlet class is given below.

ControllerMail.java

package com.sendmail.controller;

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;

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

public class ControllerMail extends HttpServlet {
    private static final long serialVersionUID = 1L;

    public ControllerMail() {
        super();
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doProcess(request,response);
    }


    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doProcess(request,response);
    }

    protected void doProcess(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
    {
        String pageType = request.getParameter("pageType");
        if(pageType.equals("SendMail"))
        {
            String to = request.getParameter("to");

            //Get the session object
              Properties props = new Properties();
              props.put("mail.smtp.host", "localhost");
              props.put("mail.smtp.socketFactory.port", "465");
              props.put("mail.smtp.socketFactory.class",
                        "javax.net.ssl.SSLSocketFactory");
              props.put("mail.smtp.auth", "true");
              props.put("mail.smtp.port", "465");

              Session session = Session.getDefaultInstance(props,
               new javax.mail.Authenticator() {
               protected PasswordAuthentication getPasswordAuthentication() {
               return new PasswordAuthentication("********@gmail.com","********");//change accordingly
               }
              });

            //compose message
              try {
               MimeMessage message = new MimeMessage(session);
               message.setFrom(new InternetAddress("********@gmail.com"));//change accordingly
               message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
               message.setSubject("Greetings");
               message.setContent("Hi,what's up","text/html");

               //send message
               Transport.send(message);

               System.out.println("message sent successfully");

              } catch (MessagingException e) {throw new RuntimeException(e);}
        }
    }

}

But when I run my project on server that mean when I right click on my SendMail.jsp page and click on "run on server",the following errors are occured.
