Hai , Can some body explain few real world applications that J2EE technologies are used? I got this as an interview Question and as a beginner I told online banking and shopping site. Is j2ee too complicated for this purpose ?
J2EE is broad by itself. Though the examples you have provided does makes sense, ideally J2EE is used when your application needs - to scale - be secured - involves heavy transactions - needs object to be persisted in relational database
Thats just a small part and there are much more to explore for you as a newb.. All The Best.
