Hi Colin,

your xmlBlaster server logs don't tell me a lot, when pinging the callback server they say:


 java.io.IOException: Server returned HTTP response code: 500 for URL: http://cbrown:1381/RPC2

 (Internal Error 500 The server encountered an unexpected condition which prevented it from 
fulfilling the request.)


The Python http (xmlrpc) callback server sends this.
Can you try to do a telnet on this port to see how your Python callback server
reacts?


Try to start xmlBlaster like:

  java org.xmlBlaster.Main -plugin/xmlrpc/debug true -trace[xmlrpc] true

and a java client like:

  java javaclients.HelloWorldSubscribe -protocol XMLRPC  -plugin/xmlrpc/debug true -trace[xmlrpc] true


You have now a functional detailed logging of the xmlrpc protocol
Looking at the ping calls and comparing them to your python variant
should clarify the problem,

regards

Marcel
