One way operation

I have encountered a problem calliing the
"operation.executeInputOnlyOperation(in_msg)" method.
The webservice is succesfully callled but a NullPointerException is then
thrown. I believe it occurs whilst trying to decode the reponse (see
"org.apache.wsif.providers.soap.apacheaxis.WSIFOperation_ApacheAxis.setR
esponseContext".) As this is a one way operation I didn't expect a
reponse from the server.  I have included the stack trace for
information.
