J2EE Beginner

Hi everybody! I dont know where to post this, I'll just try it here.
I am a Software Developer and to tell you the truth I really don't know how J2EE works, but
what we are developing right now is a system that uses J2EE technology, then using OC4J for deployment.

My problem is I really want to study J2EE, EJB, etc. But I don't know where to start.
All the resources in the internet are too technical for me.

Can you suggest a lesson path or study path for me to start with learning J2EE, do I really
need to know the technical details so that it will help me land a better job?
And now I'm thinking of getting certified as a Java Programmer. But all I need to know is
how should I start studying.

Thanks in advance for your help.

J2EE is a really large set of APIs covering a number of complex technologies.  Most of us only use a subset of these, so I recommend you find a way to limit what you study to what your immediate needs are.  Are you going to be using EJBs?  Many are moving away from these (at least CMP entity beans).  If you are going to be working with these, I suggest you start with RMI (see sun's tutorial) because using proxies for remote objects is the key to understanding EJBs.

If you are going to be using JSP's, there are a number of books/websites that can help with this.

If you are using OC4J, there are lot of good tutorials on the OTN website.  To the extent you are using Oracle-specific technolgiy (ADF, etc.), look under JDeveloper tutorials for these.

If you can point us to what specific J2EE technologies you will be using, and your level of comfort with J2SE, we can give you a better idea of where to go.  Good luck!

For J2EE , the best one is of course http://java.sun.com/j2ee/ and there are no of other resources which provide you useful information.
 You could strat with Servlets , JSP , and advanced JDBC and then teh business logic thats EJBs and JMS and also J2EE-XML :)
Install and configure Tomcat so that you could practice JSPs and install for example IBM WebSphere so go deep into the J2EE

For tutorials
www.theserverside.com is really good , you will find many good examles
and another good one is
www.javaboutique.com and www.javaworld.com

is EJB the heart of the J2EE process? or not?

girionisCommented:
Not necessarily. When you are talking abotu J2EE you do not necessarily refer to EJBs. Servlet/JSP pages are also part of the J2EE specification, so I'd say Servlets/JSP are the heart of J2EE but this is debatable.

Servlets, JSPs, Messaging, and way more.  Most people only think of EJB's but J2EE is a large collection of APIs.
