Hi all,
I am having trouble deploying a BPEL process because there are some errors
reported by BPEL compiler.
The exception is as follows.
java.lang.IllegalStateException: XPath string and xpath node are both null

....
There are several similar assign activities which I think may be the cause
of the problem.
<assign>
<copy>
<from
expression="concat(bpws:getVariableData('probeInput','probeData'),bpws:getVariableData('probeInput','probeName'))"/>
<to variable="probeInput" part="probeData"/>
</copy>
</assign>
Variable definitions are as follows
<variables>
<variable name="request" messageType="wns:requestMessage"/>
<variable name="probeInput" messageType="wns:probeMessage"/>
<variable name="reply" messageType="wns:replyMessage"/>
<variable name="internalState"
messageType="wns:internalProcessData"/>
</variables>
Variable probeInput message definition
<wsdl:message name="probeMessage">
<wsdl:part name="probeName" type="xsd:string" />
<wsdl:part name="probeData" type="xsd:string" />
</wsdl:message>
I have checked for the correctness of the message element names etc. But yet
to find the reason for this behavior. Can some one please tell me what I am
doing wrong here? I have attached the BPEL process and the corresponding
wsdl file for your reference.
Best Regards,
Chamith
