I am trying to use JavaMAIL but unable to send mail: I need help!

Below I am put the entire code:

It shows the Error...

[William Brogden]

That looks like the mail server was not listening on the address you used.

If this was my problem I would get my mail sending code running outside the servlet environment in some sort of stand-alone test configuration first.

There are so many things which can go wrong - I would start with the core mail sending code.

Thanks William... but I tried the same by creating Session.getInstance(Prop,Auth) and it was a successful attempt... below I am mentioning the code:


MailAuthenticator.java

import javax.mail.*;


public class MailAuthenticator extends Authenticator 
{
	public PasswordAuthentication getPasswordAuthentication()
	{
		return new PasswordAuthentication("[e-mail]","info456");
	}
}

LoginRegisterAuthenticateImpl.java

    
import javax.mail.*;
... 


public class LoginRegisterAuthenticateImpl 
{

	public String getAuthenticated(RegisterDTO regDto){
		
		Some code...
		
		//----------- Verification Mail -------------------------------		
		try
		{
			Properties props = new Properties();			
			props.put("mail.smtp.host", "mail.xxxxxxxxx.com");
			props.put("mail.smtp.auth", "true");			
			
			Authenticator mailAuth = new MailAuthenticator();
			Session session = Session.getInstance(props,mailAuth);		
			session.setDebug(false);
			
			Message message = new MimeMessage(Session.getInstance(props, mailAuth));
			message.setFrom(new InternetAddress("[e-mail]"));
			InternetAddress[] addTo = new InternetAddress[1];
			addTo[0] = new InternetAddress("[e-mail]"); 
			message.setRecipients(Message.RecipientType.TO, addTo);
			
			
			message.setSubject("It is not trial");
			message.setText("Now it is Modified: ");
			
			Transport.send(message);
		}
		catch(Exception ex)
		{
			ex.printStackTrace();
		}
		
		
		return new String();
	}
}

Perhaps the problem is with the configuration settings in context.xml. I don't know how to fix.

[ramnna jain]

I want to know how to configure Resource tag in context.xml ....


or what else should be done to send mail .... configuring it in the context.

I tried few changes in my resources attributes now I am getting new Error:

    
<Resource name="mail/Session"

		 mail.smtp.auth="false"

		 mail.password="info456"
		 mail.from="[e-mail]"  
		 mail.debug="false"  />

I think the user is not getting authenticated.
Is there any buddy can help me to resolve the problem...?
