Hi,all!

I am getting start with JXME. There are some differences between JXME and JXTA.In JXME, we must get peer ID from relay at first.So the question is how can I get the peer ID from relay.
Some articles mention that the JXME client must send HTTP request to relay and ask for a peer ID. The HTTP request is like this:

GET /unknown-unknown?0,-1,http://172.16.0.37:2481/
EndpointService:jxta-NetGroup/
uuid-DEADBEEFDEAFBABAFEEDBABE0000000F05/pid HTTP/1.1
Connection: close
Content-Length: 0
User-Agent: UNTRUSTED/1.0
Host: 172.16.0.37:2481 

I also want to know whether the relay provide this service and how I can get the document ahout there services.
Thks!
