On deploy: java.lang.NullPointerException in WsdlCompleterUtil.isAncestor

Question

Hello,
I downloaded JDeveloper 10.1.3.2.0 and Oracle BPEL PM 10.1.3.1.0 yesterday and built simple BPEL process with one single invoke activity. The BPEL process validates in JDeveloper but on deploy I get following stack trace -
Process "ZMFFlow" (revision "v2007_05_30__54686") successfully compiled.

My BPEL process is -

Sorry for the long post but I would also like to send in wsdls so that someone can try to reproduce the problem. Can anyone tell me what this error means? What could be wrong in my process or wsdls?
Thank you,

Answer 1

I think I have found when I get this error and probably I have found a bug. I will appreciate if someone can confirm this.
In my BPEL project setup, my BPEL process's wsdl file imports another wsdl from different namespace. Here is sample snippet -
<wsdl:definitions targetNamespace="http://namespace/1">
<wsdl:import namespace="http://namespace/2" location="resources/another.wsdl"/>
<plnk:partnerLinkType....../>
</wsdl:definitions>
Please let me know. I checked the bundled samples with Oracle BPEL PM and did not find any similar case where process wsdl imports another wsdl.
Thank you.
