problem with dynamic epr
Hi All,
I tried to set endpoint reference from input variable.
In Invoke.bpel I declare variable:
<bpel:variable name="WebServiceUrl" messageType="tns:EndpointMessage" />
EndpointMessage is a message in Invoke.wsdl
<message name="EndpointMessage" >
<part name="payload" element="wsa:EndpointReference" />
</message>
and I set endpoint:
<bpel:assign>
<bpel:copy>
<bpel:from>$input.payload/tns:webServiceUrl</bpel:from>
<bpel:to variable="WebServiceUrl" part="payload"/>
</bpel:copy>
<bpel:copy>
<bpel:from variable="WebServiceUrl" part="payload"/>
<bpel:to partnerLink="TaskServiceClient"/>
</bpel:copy>
</bpel:assign>
It works in apache ode 1.2, but it not in 1.3.4.
When I start process I get error bellow.
Can somebody help me with this problem?
Thanks,
Rafal

Hi Rafal,
a NPE is not exactly what we want to see here :) What it however says is
that the wsa:Address element could not be extracted from the message, so
I assume that the XML nesting was somehow wrong.
Could you please set the log level for "org.apache.ode.bpel.epr" to
DEBUG, run the example again and look for "Setting a WSAEndpoint value"?
With that log information it should be easier to understand what is
going wrong. Also, did you check out the DynPartner example shipped with
ODE? I recently tried it with ODE 1.3.5rc and it worked as expected.
HTH,
Tammo
