Which folder is that java mail .jar in?
How are you setting the classpath for your application?
When I Googled for Java Mail, I found a download page where Message appears to be in mail.jar. Please confirm you have got that mail.jar file in the classpath as well.

Thanks for the Reply. I had added this jar in the eclipse --> preferences-->java-->BuildPath-->classpath variables.
