Dear All I publish WebSerivce (vid EJB EntryPoint) sucessfully But When I use a remote client to call it , I always get below exception javax.xml.rpc.ServiceException: Cannot find ServiceFactory implementation 1) Below is a snippet of my remote client code. Could any of you give me some hints ? 2) Is there any easy way to test web service (via EJB Entry Point) like SUN AppServer(glassfish), web service can be tested on Server's Admin console. no need to write remote client to test it Thanks. URL url = new URL("http://bearingp-9o5cye:8080/psm-aapt-AAPT_CD005_V04/ProductServiceMgmtWebServiceBean?wsdl"); QName serviceName = new QName("ProductServiceMgmtWebServiceBean"); ServiceFactory factory = ServiceFactory.newInstance(); Service service = factory.createService(url, serviceName); webService = (ProductServiceMgmtWebService) service.getPort(ProductServiceMgmtWebService.class); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3987155#...
