SOAP Fault while invoking ISG Service through BPEL

Question

Hi,
I am trying to invoke a EBS R12 pl sql API exposed as a web service through integrated SOA gateway. But i am hitting the same error for different API`s that i have tried with. the error is :
<remoteFault>
<part name="summary">
<summary>Error occured while service was processing.</summary>
</part>
<part name="detail">
<detail>oracle.j2ee.ws.client.jaxws.JRFSOAPFaultException: Client received SOAP Fault from server : Error occured while service was processing.</detail>
</part>
<part name="code">
<code>{http://schemas.xmlsoap.org/soap/envelope/}Server</code>
</part>
</remoteFault>
I have supplied the r12 credentials through the composite WS Policies and the header details for the API as well. I am also able to call the API through PL/SQL code. Any reason why this error is occuring.

My 2 cents here - are you using ?wsdl for accessing the wsdl? Reason I am asking this is because you get a fault message as you have posted, i.e., The action (ABC#) did not identify an operation, looks like you are hitting the service directly instead of querying for the wsdl. Also, while you are using this wsdl in your PS/BS, for example, maybe in a route action, are you sure you are selecting the operation from the list of operations this wsdl has?
