> and I think I have fixed a bug in {{jbossws-common-3.1.5}}.
> I have downloaded the latest version of {{jbossws-common-master}} from github (with which the problem was still showing).
> Then I fixed the class {{org/jboss/ws/common/utils/DelegateClassLoader.java}} changing this:
> {code}
> /** {@inheritDoc} */
> @Override
> public InputStream getResourceAsStream(final String name)
> {
> InputStream is = parent.getResourceAsStream(name);
> return (is == null) ? delegate.getResourceAsStream(name) : is;
> }
> {code}
> to this:
> {code}
> /** {@inheritDoc} */
> @Override
> public InputStream getResourceAsStream(final String name)
> {
> InputStream is = null;
> if (parent != null)
> {
> is = parent.getResourceAsStream(name);
> }
> return (is == null) ? delegate.getResourceAsStream(name) : is;
> }
> {code}
> and then built again the jbossws-common jar and replaced the (suspected) faulty one under the WildFly modules. With the new jar the webservice can be registered.
