I'm trying to invoke a RPC/encoded webservice through a esbws file. But it does not let me use xpath on the incoming xml. The only options available in the dropdown for transformation are None, Constant and Discard parameter. Is there any other way to map the incoming xml to the WSDL parameters.
The ESBWS has one parameter -- the result of the invocation. When you add this to the esbp, then you can transform it in the mapping.
