When I try to connect to a web service using I get an Axis Fault error:

JAXRPCException: the number of parameters passed in (1) doesn't match the number of IN/INOUT parameters (11) in the addParamters() call. I am using Spring and am very new to this. I assume that in the marshalling call all of my parameters are being lumped together as one but the webservice expects 11? Where is this happening? Why is it happening? How can I fix it?
Thanks!
