I wasted 3 days trying to find a solution thinking that the problem was in my dependencies
with xerces or any other xml resolver.
Then I decided to checkout the code near the root cause:
{code}
Caused by: java.lang.NullPointerException

at __redirected.__RedirectedUtils.findProviderClassNames(__RedirectedUtils.java:147)

{code}
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.
