Hi!
I am trying to implement a very simple BPEL process using Eclipse BPEL with
the latest updates and ODE integration provided last week. It's just to test
if I can call a webservice which runs in the same engine like the calling
one. The process can be deployed an compiled, but when I call it, I get an
error:
>From the log:
910406 [ODEServer-4] ERROR org.apache.ode.bpel.runtime.ASSIGN - Assignment
Fault: {
http://docs.oasis-open.org/wsbpel/2.0/process/executable}selectionFailure,lineNo=64,faultExplanation=Noresults
for expression: {OXPath10Expression xs:pDocType}
As an answer:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring xmlns:axis2ns2="

">axis2ns2:selectionFailure</faultstring>
<detail/>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
I tried to solve the problem with the hints from this list which are all
about initialization, but I don't come any further. Here is my BPEL process:
