Thanks Peter for the taking time to reply. 1.What is strange in my JBOSS 4.2..2 installation is that I have not finding following jars in my $JBOSS_HOME/client/ path :- jbossws-native-jaxws.jar jbossws-native-core.jar client/jbossws-native-jaxws-ext.jar client/jbossws-native-jaxrpc.jar jbossws-native-saaj.jar In fact these jars are not available in any path of my JBOSS installation. Is the normal JBOSS 4.2.2 installation does not include all these jars . do I need to insatll JBOSS JAX-WS integartion layer in order to make JBOSS JAXWS compliant. 2.I made the client stub with wsconsume and I checked the all the names used in the both stub and "stepts to call to make web service using WSDL location". The all the names used both in the stub and in the "stepts to call to make web service using WSDL location" are same. In Fact, I am not able to call deployed web service either with stub created by wsconsume or by using WSDL location primitive. Could please let me know what could be the reason of my problem and what is its soution. with best rehards, Ajay Kumar, ST Microelectronics Ltd., Noida, India.
