jakarta ee – How should a one start learning Java Enterprise Edition?
If you are starting try Head First Series.
Depends on what you are willing to learn. Desktop or web applications.
If I were you, I would start learning Eclipse RCP, build a small app with some views and editors, then start to read on Java EE6 with Glassfish3. This is by far the best EE book Ive found out there, and its available in PDF.
Tame the GF3 server, make a database, write some business logic, layer your app, apply design patterns.
On the other hand, if you want a web app, just pick a Java Web Framework, write a small app, then read the EE6 book. As you can see, either way, you still have to read it.
