Cleaning up the callback EPR....

The current callback into an awaiting BPM process is via this chunk of XML injected into the reply-to:

<wsa:From xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing"><wsa:Address>logical:JBossESB-Internal#JBpmCallbackService</wsa:Address><wsa:ReferenceProperties><jbossesb:esbToBpmVars xmlns:jbossesb="http://schemas.jboss.com/ws/2007/01/jbossesb">&lt;esbToBpmVars>&lt;mapping esb="BODY_CONTENT" bpm="theBody"/>&lt;/esbToBpmVars></jbossesb:esbToBpmVars><jbossesb:jbpmTokenId xmlns:jbossesb="http://schemas.jboss.com/ws/2007/01/jbossesb">406</jbossesb:jbpmTokenId><jbossesb:jbpmNodeId xmlns:jbossesb="http://schemas.jboss.com/ws/2007/01/jbossesb">30</jbossesb:jbpmNodeId><jbossesb:jbpmProcessInstId xmlns:jbossesb="http://schemas.jboss.com/ws/2007/01/jbossesb">166</jbossesb:jbpmProcessInstId><jbossesb:jbpmProcessNodeVersionCounter30_406 xmlns:jbossesb="http://schemas.jboss.com/ws/2007/01/jbossesb">0</jbossesb:jbpmProcessNodeVersionCounter30_406><jbossesb:type xmlns:jbossesb="http://schemas.jboss.com/ws/2007/01/jbossesb">urn:jboss/esb/epr/type/logical</jbossesb:type></wsa:ReferenceProperties></wsa:From>

It is injected via a custom action like so:
message.getHeader().getCall().setTo(epr); 
where epr equals the content listed above.

This is essentially our "cookie" for managing the conversation between ESB & the process instance. This chunk of XML is a bit unwieldy, especially if must go out to a business partner or actual client application.  It also requires a custom action to be created.

An easier to use correlation solution should be created so that it works more like the older model of signal (out of the box action) & token id (a simpler "cookie").
