Problem using XML-RPC and RMI above JXTA

Hi all,

We are using JXTA and we are veri interested on using XML-RPC or RMI 
with JXTA but in the JXTA official website we haven't found any 
implementation of RMI and the XML-RPC implementation doesn't seem to 
work very right.
We are looking for RMI or XML-RPC implementations through internet, but 
we aren't finding very much.
Somebody could help us?

Thanks!
