Why J2EE so popular?

I learn JSP, Servlet and SQL. But it's not good enough because most of the job postings requires J2EE experience.

Why J2EE so nice?

Mike,
JSPs and servlets are part of J2EE. So you do have some knowledge of J2EE. EJBs give transactional support and several other powerful features.

Someone told me J2EE has XML too, I read some XML (it's like home made HTML tags) and I have no idea how Java could use it. Maybe it just doesn't click in my head because I don't see the purpose of have XML.

But most job posting wants XML knowledge, why? Do you have some basic example with java and xml? I finds best way to understand is to see the code.

Thanx,

Mike

this question will be best answered by a book that covers 'Java and XML'.

With respect to the value of XML, it is used everywhere in the J2EE context. Including web server setup, web framework development, web services etc etc. So, knowledge of XML is very much required and useful.

If you have good knowledge on servlets and JSPs complete SCWCD and I am sure you'll get selected for a good job , after all EJB is just another part of J2ee, and if you show you have the right aptitude in servlets and JSPs with good OO basics it is enough, I have interviewed around 50 people and found that none of them have good basics either java basics or the basic servlet paradigm...It is difficult to find people with good knowledge and right bent..
