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.
