Hi All,

I have written web services and configured with spring framework but I am getting exception when invoking services. Exceptions stack trace are given below -

com.sun.xml.ws.server.sei.EndpointMethodHandler invoke
SEVERE: object is not an instance of declaring class
java.lang.IllegalArgumentException: object is not an instance of declaring class

i am testing our services using SOAP UI and getting above mentioed exception. I think some how the object creation from the xml is not acceptable to webservices

I am confused what is happening
