Hi

I have been out of Java for 3 years now my company suddenly want to take over couple of J2EE applications for doing some enhancements. Earlier I hevnt done much with J2EE only core Java. I dont have much time to learn all the J2EE techlogies. I am just wondering what should I do so that I get a good hold of the J2EE app I am going to support. The problem is I dont have a design document or anything just the workspace. Please advise what is the best way to analyze the code flow.

Thanks in addvance

J2EE is less like one technology, and more like a whole bunch of technologies... So, my answer would be it depends on the application.

If the application is a web app, then you need to get up to speed on servlets (or even JSP). If the application uses EJBs, then you need to get up to speed on that. If the application is a web service, then you need to get up to speed on that. etc. etc.

I don't think this is a "beginner's" question. We usually discuss EE on another forum: moving thread.
 
It is sorta covered in the JavaRanch Style Guide.
