Guys J2EE is the technology area which emcompasses Servlets, JSPs and EJBs.

Unless you have other priorities, it would be advisable, to learn Servlets, JSPs and EJBs, in that order. Of course at times, we have to practice Servlets and JSPs together, but it is better to go for EJBs after a through understanding of Servlets and JSPs. Reason being, architecture of EJBs is much more complicated then that of Servlets. So once you really understand Servlets, it would become much more simple to go thru EJBs.

Since you already know Java, my suggestion would be you attempt to complete SCWCD 1.4. This exam covers Servlets, JSPs, regular Javabeans, Tag libraries. There is an excellent book Head First Servlets avaialble for this exam preparation. Alternatively, i read SCWCD exam study kit by Hanumanth deshmuk, which is also an excellent book.

For EJBs, we have Head First EJBs, which i am currently reading for my SCBCD (EJBS will be testing in this certification), which is an excellent and best selling book in EJB area.

Good Luck

better go with servlet first, then jsp

after these you should know some of the popular design patterns and frameworks. so then i recommmend you to get into

struts framework, then
entity beans, then
session beans, then
message driven beans and JMS, then
hibernate, then then then.

wish you luck.

adeel .... i dont know about you but i'd put entity beans at the BOTTOM of that list.

At the few companies i have been at session beans are DEFINETLY used a LOT more than entity.
beginer> Session beans are great to encapsulate transactions.

And MDB's and JMS are starting to be used more imho, or at least at the last 2 jobs i have been at. It really depends on the user, if you think there is something in your program that needs asynhcronous processing, this is a great alternative.
