Familiar with Java, want to get into J2EE.


I'm familiar with Java Programming (also C++ and other languages), but I want to get into J2EE to make my skills more marketable.

I've had a play with the Macs Java environment. It looks cool. I've picked up some books on JavaBeans and Enterprise programming.

So what do I need to play around with J2EE on my Mac? How do I write and run n-tier services? Is there an free enterprise server somewhere that I can download?

Apologies that I don't know too much about J2EE tools and development environments.
