Java P2P framework NOT JXTA/JXSE

Question

I need a Java framework to implement a simple P2P protocol which should have at least the following features:

• peer organization (join, discovery)
• XML message exchange
• query

I do not want to use JXTA/JXSE, any alternatives (a part from the DIY)?

Answer 1

The OP made an edit (now deleted by someone else) to say that FreePastry worked for them.

Answer 2

I've been looking for a P2P java framework for about 12 months now.

I was reluctant to use JXTA for two reasons. Firstly it is quite complex even for setting up simple P2P sockets. Then literature is really poor. Finally there is no more development on it now.

That said, I did not find any other suitable alternative. Hence I learned JXTA.
I managed to get pretty much what I wanted even though I'm facing some tech issues and I will have to dive into JXTA source code to better understand why reliable streams are closed randomly.

I'm interested to understand if you find another framework.
