I am getting XmlMarshalException

Hi All,

I have imported a web service model into Web Dynpro application and done the binding.

When i deploy the application , I am getting following error.

Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.XmlMarshalException: XML Serialization Error. Property [RETURN] of class [com.abc.model.proxies.types.BAPI_NAME] must exist and can not be null. This is required by schema description.

Appreciate any help in this.

Regards,

Venkat
