In my application,we already implemented it so we cant go for javamail.That does not make sense. Your 'implementation' does not work so you have not yet fully 'implemented' it. Using Javamail takes about 4 lines of code to do what you have done so far and it will work.
Please suggest me regarding this,so that I can go ahead and resolve it.Use the Javamail API.
