Hi,

I just completed my SCJP 5.0.

I'd like to learn J2EE next. Please guideme.

What are the various topics I'll have to learn?? Also, does the Sun Java System Application Server provide complete support for J2EE 5.0 specs??

I do not want to use commercial servers like websphere and weblogic. At the same time I want support for J2EE 5.0 specs.

Please help.

The version that comes with the download has support for that version of the spec.
So the appserver that comes with JEE 5.0 (no longer called J2EE) has support for that, the one that comes with J2EE 1.4 has support for that.

Which parts you're going to need depends greatly on what you want to do. It's too large a platform by large to learn all at once, focus on a part of it (like Servlet/JSP or EJB) and master that before moving on to the next.

AFAIK the reference implementation is at the moment the only one that provides full support for the latest specs.
That does mean that your knowledge will be useless for quite a while in the real world as the older specs will remain prevalent with customers/employers for some years to come.

I'm currently in my final year of graduation. I still have an year to go before I enter the industry. I hope that JEE 5.0 would be popular by then.

Also, someone said that the Sun application server does not have support for more advanced features like session tracking. Is this true? BTW I do not know what is session tracking. Is it very important?
