[jboss-dev] Remoting 3.0

Sure. In the 4.2 version of ESB we're using a version that is based  
on the original WS-Addressing implementation we developed in Arjuna  
for the Web Services transactions product back in 2004 and used for  
interoperability testing with Microsoft, IBM etc. It's based on the  
2004 version of WS-A (http://www.ibm.com/developerworks/library/ 
specification/ws-add/)

We have a new version for the next major release of ESB based on the  
2006 release of WS-A (tested here http://www.w3.org/2002/ws/addr/ 
testsuite/), but the concepts are pretty much the same (basically you  
lose ReferenceProperties).

This class is the one people are expected to develop endpoint  
references (EPRs) against:

http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/core/ 
rosetta/src/org/jboss/soa/esb/addressing/EPR.java

But this one is the one that does the real work:

http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/core/ 
rosetta/src/org/jboss/soa/esb/addressing/PortReference.java

BTW, URI would be fine too. EPRs are a superset.
