Tom Uijldert commented on JBWS-4095:
------------------------------------
Had exactly this problem and solved it by backpatching this solution into 3.1.3.Final version of my deployment.
However, another WAR deployment of mine is not affected by this...
Major difference between the two is that the problematic WAR defines 2 servlets, the other one only 1.
Could that be causing it..?

> 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}
> /** {@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.
