Setup a free java development environment

[Eric Lavarde <Eric.Lavarde@bawue.de>]

Hi,

I'm new to Java development and Debian, but it couldn't stay unnoticed 
to  me that there is some effort placed in using free Java alternatives.

I'd be happy to support this effort, but it's all very confusing to me 
(too many alternatives, basically) and I still need the Sun Java on my 
machine.

So, is there somewhere a document that explains how to setup a free java 
development environment in parallel to a Sun Java environment, limiting 
the risk of cross-pollution? Plus some explanations on which free 
VM/tools are good/best for what?

Thanks, Eric
