Today , i have faced this error when i try to deploy SOA composite to the server from jdeveloper . where the deployment process is failed and i have received this exception in the jdeveloper window log , to overcome this issue i did some searches to find out solution and i found useful link here .
In the above link it suggest that reason of this error is the mismatch between WSDL url in composite and BPEL where one is pointing to server while other to MDS .
however, in my case the problem was removing SOAP component from composite without removing the in\out variables of Invoke after removing the INOKE itself .
when i deleted the variable everything worked and the composite is deployed .
