Hello,
If your planning for buying books Id recommend the
Java Enterprise in a Nutshell book from Oreilly, and the Deitel & Deitel Advanced Java 2 how to Program books.
Both books are good, the latter is a bit of a dry read, but has lots of code examples and goes through the code almost line by line!
You can get both books from Amazon. Unfortunately theyre not available as ebooks or free downloads.
Finally you could also try downloading the
J2EE Tutorial. I suggest you hit the
Sun Java Website hard and have a good look round what they have to offer. You can also download the J2EE reference implentation here as well.
Cheers and good luck!
Mark
