I have been struggling with the following error the last couple of days can you please help!

I generated my server and client code using the wsdl2java tool from a wsdl 2.0 file. When invoking the webservice I am getting the following error:

org.apache.axis2.AxisFault: The endpoint reference (EPR) for the
Operation not found is
/axis2/services/MyService/authentication/?username=Denise345&password=xxxxx
and the WSA Action = null

My service is displayed on the axis2 webpage with all available methods. Here is the output from TcpMon
