Hi guys, Now I focus on extending wtp web service framework to support JBoss WS. To do this task, we must firstly create a dynamic web project and then generate web service or web service client codes. So far I can create web service and web service client. For user's convenience I generate a client sample to call web service. Because I use the WTP dynamic project and jboss server, when the project is created, all the jars that are from jboss server lib folder and client folder are added to project classpath. When I run the web service client sample to call web service, a issue occurs. And after I google this issue, I found a same issue. I know the issue will be fixed by removing jaxws-rt.jar and jaxws-tools.jar from classpath. But this looks like jaxws in JBoss is "incomplete" or something, and I want to know why this issue occurs? the link: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4063438#... the client sample codes: System.out.println("***********************"); System.out.println("Create Web Service Client..."); HelloWorldService service1 = new HelloWorldService(); System.out.println("Create Web Service..."); HelloWorld port1 = service1.getHelloWorldPort(); System.out.println("Create Web Service Operation..."); System.out.println("Server said: " + port1.sayHello()); System.out.println("***********************"); the issue: Exception in thread "main" javax.xml.ws.WebServiceException: Unable to load Provider: Failed to load javax.xml.ws.spi.Provider: com.sun.xml.ws.spi.ProviderImpl at javax.xml.ws.spi.Provider.provider(Provider.java:98) at javax.xml.ws.Service.(Service.java:83) at org.example.www.helloworld.HelloWorldService.(HelloWorldService.java:40) at org.example.www.helloworld.clientsample.ClientSample.main(ClientSample.java:10) Caused by: java.lang.IllegalStateException: Failed to load javax.xml.ws.spi.Provider: com.sun.xml.ws.spi.ProviderImpl at javax.xml.ws.spi.ProviderLoader.loadProvider(ProviderLoader.java:96) at javax.xml.ws.spi.Provider.provider(Provider.java:90) ... 3 more Caused by: java.lang.ExceptionInInitializerError at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at java.lang.Class.newInstance0(Class.java:350) at java.lang.Class.newInstance(Class.java:303) at javax.xml.ws.spi.ProviderLoader.loadProvider(ProviderLoader.java:91) ... 4 more Caused by: javax.xml.ws.WebServiceException: Error creating JAXBContext for W3CEndpointReference. at com.sun.xml.ws.spi.ProviderImpl.getEPRJaxbContext(ProviderImpl.java:188) at com.sun.xml.ws.spi.ProviderImpl.(ProviderImpl.java:65) ... 11 more Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions Two classes have the same XML type name "address".
