Please try directly using the Sun's tools. The exception you get comes from the Sun's impl (the jbossws-native jaxws tooling is basically wrapper of the Sun's one). If you still get the exception, please fill it directly to Sun. Othere wise post here again and create the jira on the JBWS project JIRA. Thanks.
