What is mail.host? Does that represent the senders hostname or recepients host?. I tried giving host as "mail.yahoo.com" and "mail.transport.protocol" as "smtp" and from id as "myid@yahoo.com" and to as "toid@xxx.com". When i run the jsp i get "Attribute mail.yahoo.com has no value" "Internal server error"..
Please give a solution and explanation about the "mail.host". I appreciate an early answer as i need it urgently.

			

			String host = "mail.yahoo.com";
			

			String to = request.getParameter("to");
			

			String from = request.getParameter("from");
			

			String subject = request.getParameter("subject");
			

			String messageText = request.getParameter("body");
			

			boolean sessionDebug = false;
			

			

			

			Properties props = System.getProperties();
			

			props.put("mail.host", host);
			

			props.put("mail.transport.protocol", "smtp");
			

			

			Session mailSession = Session.getDefaultInstance(props);
			

			

			mailSession.setDebug(sessionDebug);
			

			

			Message msg = new MimeMessage(mailSession);
			

			

			msg.setForm(new InternetAddress(from));
			

			InternetAddress[] address = {new InternetAddress(to)};
			

			

			msg.setRecipients(Message.RecipientType.TO, address);
			

			msg.setSubject(subject);
			

			msg.setSentDate(new Date());
			

			msg.setText(messageText);
			

			

			Transport.send(msg);
			

			

			out.println("Mail was sent to " + to);
			

			out.println("Mail from " + from);
			

			out.println("Using Host" + host +".");
