Nested OSGi Bundle Problem

[mreinhardt]

I've got a problem with my app migrating from JBoss 4.2.3 to 7.1. My Code does't load the bundle any more:

public void start(ClassLoader classLoader, String bundlePath) throws IOException, BundleException {
    // check that the directory where the bundles are deployed is valid
    AssertionUtil.assertNotNull("bundlePath", bundlePath);
    AssertionUtil.assertNotNull("classLoader", classLoader);
    classLoader.getResource("HLRPos-EJB.jar");
    URL bundleURL = classLoader.getResource(bundlePath);
    if (bundleURL == null) {
      throw new FileNotFoundException("'" + bundlePath + "' cannot be found in the classloader '" + classLoader + "'");
    }
    
    if (bundleURL.getProtocol().equals("file")) {
      File bundleDirAsFile;
      try {
        bundleDirAsFile = new File(bundleURL.toURI());
      } catch (URISyntaxException ex) {
        throw new IOException(ex);
      }
      start(bundleDirAsFile);
      
    } else if (bundleURL.getProtocol().equals("jar")) {
      /* A JAR path */
      Collection < String > jarBundles = new ArrayList < String >();
      String jarPath = bundleURL.getPath().substring(5, bundleURL.getPath().indexOf("!")); //strip out only the JAR file
      JarFile jar = new JarFile(URLDecoder.decode(jarPath, "UTF-8"));
      Enumeration<JarEntry> entries = jar.entries(); //gives ALL entries in jar
      while(entries.hasMoreElements()) {
        JarEntry entry = entries.nextElement();
        String name = entry.getName();
        if (name.startsWith(bundlePath) && name.endsWith(".jar")) {
          jarBundles.add( "jar:file:" + jarPath + "!/" + name);
        }
      }
      start(jarBundles);
    } else {
      throw new IOException("cannot handle URL: " + bundleURL);
    }

bundleURL is always null. Any ideas?

My App-Structure is the following

MyApp.ear
--> lib
          --> *.jar
          --> plugins
               --> myPlug.jar

-->MyApp-EJB.war
-->MyApp-Web.war
          --> lib
                    -->ajax4jsf-1.1.1.jar
                    -->commons-el-1.0.jar
                    -->jdbc2_0-stdext.jar
                    -->jettison-1.1.jar
                    -->jsr311-api-1.1.1.jar
                    -->myfaces-api-1.2.11.jar
                    -->oscache-2.3.2.jar
                    -->standard.jar
                    -->asm-3.1.jar
                    -->flexjson-2.1.jar
                    -->jersey-bundle-1.6.jar
                    -->jsf-facelets-1.1.15-seam.jar
                    -->jstl-1.1.0.jar
                    -->myfaces-impl-1.2.11.jar
                    -->saxon9he.jar
                    -->tomahawk-1.1.11.jar

myPlug.jar is an OSGI bundle...

Any ideas?
