Hello,
I have a problem with calling my BPEL-Process. I get a /bpel:selection
failure/ when trying to do the call.
Since the same Process runs without problems under ActiveBPEL when using
the extension of the engine I know that I have to initialize the
variables first. But I don't know how to do this. Following the relevant
parts of my .wsdl and .bpel files.
---WSDL---

<bpel:to>$doTransformationRequest.parameters/ns1:thirdTrans</bpel:to>
</bpel:copy>
</bpel:assign>
I have tried the following constellations, but any of them works.
----------First-------
<bpel:copy>
<bpel:from>
<ns1:doTransformationRequest>
<firstTrans xmlns="">0.0 </firstTrans>
</ns1:doTransformationRequest>
</bpel:from>
<bpel:to>$doTransformationRequest.parameters/ns1:doTransformationRequest
</bpel:to>
</bpel:copy>
--------Second---------
<bpel:copy>
<bpel:from>
<bpel:literal>
<ns1:doTransformationRequest>
<ns1:firstTrans/>
</ns1:doTransformationRequest>
</bpel:literal>
</bpel:from>
<bpel:to>$doTransformationRequest.parameters</bpel:to>
</bpel:copy>
----------Third -------------
<bpel:copy>
<bpel:from>
<ns1:doTransformationRequest>
<firstTrans xmlns="http://sequence.Transformation";>0.0 </firstTrans>
</ns1:doTransformationRequest>
</bpel:from>
<bpel:to>$doTransformationRequest.parameters/ns1:doTransformationRequest
</bpel:to>
</bpel:copy>
--------Fourth---------
<bpel:copy>
<bpel:from>
<ns1:doTransformationRequest>
<firstTrans>0.0</firstTrans>
</ns1:doTransformationRequest>
</bpel:from>
<bpel:to>$doTransformationRequest.parameters/ns1:doTransformationRequest
</bpel:to>
</bpel:copy>
Can someone please help me. I don't know how the right syntax of
initialzing a variable is.
