WS-addressing EPR's
I've just deployed my first BPEL process and have just tried setting
EPRS dynamically following the examples in the user-guide. If I do a
<assign name="AssignAgentPartnerLinkWSA">
<copy>
<from>
<literal>
<sref:service-ref>
<soap:address
location="http://localhost:9300/p2pd/servlet/dispatch"/>
</sref:service-ref>
</literal>
</from>
<to partnerLink="AgentServicePartnerLink"/>
</copy>
</assign>
Everything is fine - but if I use the WS-addressing style
<assign name="AssignAgentPartnerLinkWSA">
<copy>
<from>
<literal>
<addr:EndpointReference
xmlns:addr="http://www.w3.org/2005/08/addressing">
<addr:Address>http://localhost:9300/p2pd/servlet/dispatch</addr:Address>
<addr:Action>runAgent</addr:Action>
</addr:EndpointReference>
</literal>
</from>
<to partnerLink="AgentServicePartnerLink"/>
</copy>
</assign>
I get the following error when the process executes
ERROR - GeronimoLog.error(104) | Couldn't find endpoint for partner EPR
<?xml version="1.0" encoding="UTF-8"?>
<service-ref xmlns="http://docs.oasis-open.org/wsbpel/2.0/serviceref">
<addr:Address
xmlns:addr="http://www.w3.org/2005/08/addressing">http://localhost:9300/
p2pd/servlet/dispatch</addr:Address>
<addr:Action
xmlns:addr="http://www.w3.org/2005/08/addressing">runAgent</addr:Action>
</service-ref>
Is there something wrong with my definition of the WS-addressing style
EPR? Also does WS-addressing EPRs support reference properties/reference
parameters? I was hoping to use those as a way to put information into
soap-headers rather than use the non-standard extension mechanism to the
<assign> operator. Would this be a possible way or is there a better way
for setting soap-headers?
Thanks
Mike

Matthieu,
Thanks for the reply. I just tried adding the <sref:service-ref> element
and am now getting the following

Hi Mike,
Your WS-Addressing endpoint should also be wrapped around a
<service-ref> element, just like you did for the SOAP address. This
wrapper is always mandated by BPEL when you do partnerLink endpoint
assignments.
Cheers,
Matthieu
