I doubt anyone will answer all that. I may be wrong, but most people here won't answer what look like interview/homework questions (i.e. do your work for you). What I can suggest is you start to look for you answers by doing the Java/J2EE etc. tutorials on Sun.

That sure is a lot of questions to ask someone to research and find the answers for, when its perfectly possible for you to do the work on your own. Also, realize that here at the JavaRanch, we're more than happy to help you with your homework, but we won't do it for you.

I'm going to move this to the "EJB and other J2EE technologies", seeing as though most of the questions fall into that category.

Thats a lot of questions to answer.
You can buy a good book on EJB/J2EE and you will find
answers to most of your questions.
I recommend you go for Professional EJB by Wrox Publishers.
