Stateless EJB sample

(CRs #369306 and #373593) The readme file in the sample/wst_samples/EJBSample/statelessEjbSample subdirectory of the EAServer installation describes creating a Web service named AddEjb. This should be SampleEjb_AddEjb. The resulting WSDL file is available at http://localhost:8080/ws/services/SampleEjb_AddEjb?wsdl, not http://localhost:8080/ws/services/AddEjb?wsdl.
