Thanks a lot peter for the reply. I am new in JbossWS and I am evaluating it for the use in our organization. 1.I did not call the web service using wsrunclient.I called it from simple java program. I found some of the the jars specified by you like jbossws-native-jaxws.jar is not available in my $JBOSS_HOME/client directory. I using JBOSS-4.2.2 application server. Should I need to install jobss JAX-WS patch for the JBOSS- 4.2.2 application server in order to run the web service.If yes, which version of jobss JAX-WS I need to install. 2.Normally a web service would be called from any environment and platform.I want to call it by using WSDL generated.Why I am getting null Service object when I tried to call the web service from its WSDL file using below code ? -- String url="http://dlhlx09.dlh.st.com:20120/mywebservice/Greeting?wsdl"; URL wsdlLocation=new URL(url); QName serviceName = new QName("http://ccc/", "GreetingService"); Service service = Service.create(wsdlLocation, serviceName); Is it only issue of JAX-WS patch which need to be installed.? best regards, Ajay kumar, ST Microleectronics Ltd., Noida,India.
