My goal for the next year is to have a solid understanding of J2EE. J2EE encompasses so many things, so I was wondering...
Should you work overview --> details? Tackle J2EE tutorial first and then explore individual topics as necessary?
Or detials --> overview? Make sure you have some knowledge of EJB, JDBC etc.
They say you eat an elephant a bite at a time, but I just don't know which byte of the J2EE elephant is better to start with.
Thanks

If you don�t start I think would be better for you start studying , JDBC, Servlets, JSP, JMS, JNDI and then go to EJBs.
A good start is reading the specifications first and then go to some tutorials (always go back to the specs. for better understanding. oh! and to the JavaRanch foruns of course).
That�s my opinion.
Have fun.

If i were you,
I would first see if i'm familiar with the basic java concepts..if im sure of myself...
I would sleep with the sun site and look through
Patterns(all kinds..for just an overall exposure to what exists)
JDBC,JNI,JNDI,JMS(though they look like many..with the right basic understanding u might even cover them in about a fortnight)
After this start with EJB again @ sunsite and go onto EJB patterns.
Download the java petstore and run the sample with focus on the app architecture and web flow. Research the struts framework and command patterns for web-app flow from apache.org to familiarize with the 3-tier architecture systems,design flaws..etc.
Visit sites like serverside.com and drill more into the collective experience of the ppl implementing j2ee solutions.
Start on matching the object impedance with relational impedance(as a knowledge of both is very crucial for designing a scalable solution) from sites like http://www.ambysoft.com/persistenceLayer.html#PersistenceWritings
Hope my 2 cents helps u in making a roadmap.
All the best
