Based on the MBean name in the error message, you did not provide a context. I am assuming that you are creating an EJB web service (POJO web services always(?) have a context). Did you provide an @WebContext annotation?
If this does not help, please post the web service code and any related configuration files.
I can' find any @WebContext annotation available to annotate my web service.
What is the fully qualified name of the annotation @WebContext annotation?
