JAX-RPC Handler failed to process the message

I am facing below issue while calling a WS and my environment is 7.1.2.
JAX-RPC Handler failed to process the message

I read in one of the posts suggesting do the below change in provider side but I do not have any control over my client code.
SoapDocumentMethod(OneWay = true) to False

Has anyone resolved this issue?

Thanks,
Faisal
