key points before going through the Spring and J2EE like, understood, developer, somebody

amy

can anybody here points the key elements (have to be understood )before understanding the J2EE and studying it ? can somebody name them please ? please tell me all of them, as  i am new to J2EE, thank you

Here is a start:  developer/techni...2EE/intro_ee5/

I suppose that is a bit like studying it, but it is impossible to wrap up Enterprise Java in a forum.
