Cannot register web service, fails with NullPointerException in DelegateClassLoader

    XMLWordPrintable

    Details

    • Steps to Reproduce:
      Hide

      Cannot be reproduced without the original source code, which is too big and I cannot upload any part of it or of the WSDL file. I guess I could send privately the wsdl file if needed.
      But I have tracked down what looks like a bug in the library jbossws-common-3.1.5.Final.jar, and I (think I) have fixed the problem in the jbossws-common-3.2.1 (master) one. With the fix the exception is not thrown any more. Please see fix in the description.

      Description

      While deploying a EAR application, which contains a WAR which is trying to register a web service, I get the follwing exception:

      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:

      Caused by: java.lang.NullPointerException
      	at org.jboss.ws.common.utils.DelegateClassLoader.getResourceAsStream(DelegateClassLoader.java:132)
      	at __redirected.__RedirectedUtils.findProviderClassNames(__RedirectedUtils.java:147)

      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:

         /** {@inheritDoc} */
         @Override
         public InputStream getResourceAsStream(final String name)
         {
            InputStream is = parent.getResourceAsStream(name);
            return (is == null) ? delegate.getResourceAsStream(name) : is;
         }
      

      to this:

         /** {@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;
         }
      

      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.
