I have been a member of the Java Community Process (JCP) for nearly ten years. My contribution so far has been to vote in elections and respond to surveys.
But recently this changed as I was selected to be a part of the Expert Group for JSR 371: Model-View-Controller (MVC 1.0) Specification. This JSR is targeted to be a part of Java EE 8.
I am looking very much forward to participating in this JSR and will post updates here now and then.
