Hi,
Just in case someone runs into the same problem, I live here my solution:
In may case the problem was the wsdl definition. I developed the web service in java and generated the wsdl with Maven. Automatically it generates the wsdl like this (I just copy the last section):
<wsdl:service name="tso-ws">
<wsdl:port name="tso-wsHttpSoap11Endpoint" binding="ns:tso-wsSoap11Binding">
<soap:address location="http://localhost:8080/axis2/services/tso-ws"/>
</wsdl:port>
<wsdl:port name="tso-wsHttpSoap12Endpoint" binding="ns:tso-wsSoap12Binding">
<soap12:address location="http://localhost:8080/axis2/services/tso-ws"/>
</wsdl:port>
<wsdl:port name="tso-wsHttpEndpoint" binding="ns:tso-wsHttpBinding">
<http:address location="http://localhost:8080/axis2/services/tso-ws"/>
</wsdl:port>
</wsdl:service>
The problem was the <wsdl:service name="tso-ws"> section. There were 3 port definitions with 3 different bindings but all of them have the same service location. So In the BPEL process I created the partner link using the service location.
I guess BPEL was using the http binding, so I deleted two of the por definitions and just left this in the <wsdl:service name="tso-ws"> section of the wsdl
<wsdl:service name="tso-ws">
<wsdl:port name="tso-wsHttpSoap12Endpoint" binding="ns:tso-wsSoap12Binding">
<soap12:address location="http://localhost:8080/axis2/services/tso-ws"/>
</wsdl:port>
By doing this, it works. I read in some forums that BPEL doesn't work with the http_post protocol so that's why I deleted that definition. And someone told me that it uses soap12 so that's why I deleted that definition also.
That's the way I solved it. Hope this helps.
