Thanks Nicole!!! I am kind of new to Inter System sand Atelier so i am also looking for the naming conventions for those packages and classes. Say if i have REST services then should i put them it it's own packages, Request and Response messages, Business service, process and operation etc. This will help me to follow some standards!!!

Actually i have installed glassfish and it works now, thanks!!!

Sorry for the late reply but i am not sure if i have Glassfish installed and how do i update glassfish
