    ProxyContext is not visible from class loader

    Manuel Valladares Newbie

      Hi,
      I am developing my first Web Service using Jboss-WS and it works fine.
      The web service is called UseOccupationsService, the method to call String getUseOccupationDescriptions(String, String) and it is using the following location: http://127.0.0.1:8080/MRE/webservices/UseOccupations.

      But when I access this page with a browser (http://127.0.0.1:8080/MRE/webservices/UseOccupations) I get the following error:

      Sorry, something seems to have gone wrong... here are the details:
      java.lang.IllegalArgumentException: interface org.jboss.mx.util.ProxyContext is not visible from class loader


      And the exception in the log is:

      [AxisServlet] Exception:
      java.lang.IllegalArgumentException: interface org.jboss.mx.util.ProxyContext is not visible from class loader

      As I said before, the web service works fine, but I am a little worried about this error. I know that the page should show a list of the web services located in the server.

      Here I send you the configuration files:

      I tried to find the same error in the forum and in google and no luck.
      Any help would be greatly appreciated.
      Thank you very much,
