Hi,

Adding to the above mail :

1)I have put the JAVAMAIL 1.4.4 folder in C:/ProgramFiles/JAVA folder and updated the path for the .jar files in classpath.
2)As i m developing in ECLIPSE i have also right clicked on project folder -->Properties-->Java Build Path -->Libraries Tab --> and added my mail.jar there through add external jars.

So now when i pasted the below code i did not see any red underlinings.
The code is :

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ page import="java.util.*" %>
<%@ page import="javax.mail.Message" %>
<%@ page import="javax.mail.MessagingException" %>
<%@ page import="javax.mail.PasswordAuthentication" %>
<%@ page import="javax.mail.Session" %>
<%@ page import="javax.mail.Transport" %>
<%@ page import="javax.mail.internet.InternetAddress" %>
<%@ page import="javax.mail.internet.MimeMessage" %>

		mailSession.setDebug(sessionDebug);
		
		Message msg = new MimeMessage(mailSession);
		msg.setFrom(new InternetAddress(from));
		InternetAddress[] address = {new InternetAddress(to)};

		msg.setSubject(subject);

		transport.connect(host, user, pass);
		try

			out.println("Email sent");
			
		}
		catch (Exception err) 
		{
			
		}
		transport.close();

When executing this i get the below error :

Sounds like the mail.jar is not being included in the WAR deployed to Tomcat.

And once you get that problem sorted out, you should read the JavaMail FAQ to find the right way to connect to Gmail. Your code is based on out-of-date examples which are still littering the internet.

And has no one mentioned that putting complex code in a JSP is a really, really, really bad thing thing to do?

Or, for that matter, that this wasn't the best forum to ask that question. We do have a forum where the JSP experts hang out!

The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.

You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.

Actually, I think this was the proper forum because I think that the question is: "How do I configure Eclipse properly to get the mail JAR into my WAR?"
