org.jboss.mx.loading.UnifiedClassLoader

A ClassLoader which loads classes from a single URL in conjunction with the {@link LoaderRepository}. Notice that this classloader does not work independently without the repository. A repository reference must be provided via the constructor or the classloader must be explicitly registered to the repository before any attempt to load a class. @author Marc Fleury @author Christoph G. Jung @author Scott Stark @author Juha Lindfors @author Adrian Brock. @version $Revision: 1.12 $

fixed default resolution behaviour

20020315 Juha Lindfors:

Support for adding your own class definitions instead of just an URL.
Removed static reference to repository. This is now set as the classloader is registered to the repository via setRepository() call.

         // since we don't have the URLs til getMBeansFromURL() is called we
         // need to add these UCLs late, after the MBean registration
         LoaderRepository ulr = LoaderRepository.getDefaultLoaderRepository();
         try
         {
            UnifiedClassLoader cl = ulr.newClassLoader(url, true);
            if (ucl == null)
               ucl = cl;


            // Keep track of the urls
            super.addURL(url);

         fail("test.implementation.loading.support.Trivial is already visible");
      }
      catch (ClassNotFoundException expected) {}


      // Add the URL to the repository twice
      UnifiedClassLoader ucl1 = lr.newClassLoader(url, true);
      UnifiedClassLoader ucl2 = lr.newClassLoader(url, true);


      // Should be able to load the class
      lr.loadClass("test.implementation.loading.support.Trivial");


      // Remove one
      ucl1.unregister();


      // Should still be able to load the class
      lr.loadClass("test.implementation.loading.support.Trivial");


      // Remove the other
      ucl2.unregister();
   }
