Here s the code for SayHelloWebService import javax.ejb.Remote; | import javax.jws.WebMethod; | import javax.jws.WebService; | import javax.jws.soap.SOAPBinding; | | @Remote | @WebService( | name = "SayHello", | targetNamespace = "http://org.jboss.ws/samples/retail/profile") | //@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE) | | public interface SayHelloWebService { | @WebMethod | public String sayHello(String name); | } PS : by the way , when i put the JAXB2.0-.jar file into the lib of the JBOSS the problem is solved.I did that without any understanding , as the exception said something like "endorsed directory....place that jar file in the xxx directory ... " now it works fine , but im not clear about why i had to place that .jar in the lib ?? that kinda thing hasnt mentioned any of the materials i reffered. could u explain the reason for that ? thanks Saji View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140282#...
