Hello all,

I am trying to embed Little-G (geronimo 1.1) in an eclipse RCP application. I want to run it in the same JVM as plugins in eclipse. To easily deploy this feature, I created an eclipse plugin that contains all the geronimo repositories (lib, var...).
Having a look at the way tomcat is embedded in the org.eclipse.tomcat plugin, I manage to launch geronimo but it stops at 14% because of a NoClassDefFoundException while
instanciating the first GBean. To avoid to use the BundleResourceHandler of eclipse when it tries to open jars, I made a test using a dedicated ClassLoader (JarFileClassLoader from geronimo).

Do you know a way to embed geronimo in eclipse using the same JVM.

Thanks you for your help.

Following the test code used to launch geronimo in the eclipse plugin (It calls the Daemon main method).

        URL[] urls = new URL[21];
        urls[0] = resolveURL("/bin/server.jar");
        urls[1] = resolveURL("/lib/geronimo-qname_1.1_spec-1.0.1.jar");
        urls[2] = resolveURL("/lib/geronimo- common-1.1.jar");
        urls[3] = resolveURL("/lib/geronimo-kernel-1.1.jar");
        urls[4] = resolveURL("/lib/geronimo-system-1.1.jar");
        urls[5] = resolveURL("/lib/geronimo- util-1.1.jar");
        urls[6] = resolveURL("/lib/cglib-nodep-2.1_3.jar");
        urls[7] = resolveURL("/lib/concurrent-1.3.4.jar");
        urls[8] = resolveURL("/lib/commons-cli-1.0.jar ");
        urls[9] = resolveURL("/lib/commons-logging-1.0.4.jar");
        urls[10] = resolveURL("/lib/log4j-1.2.8.jar");
        urls[11] = resolveURL("/lib/mx4j-3.0.1.jar");
        urls[12] = resolveURL("/lib/mx4j-remote-3.0.1.jar");
        urls[13] = resolveURL("/lib/endorsed/xercesImpl-2.6.2.jar");
        urls[14] = resolveURL("/lib/endorsed/xmlParserAPIs-2.2.1.jar ");
        urls[15] = resolveURL("/lib/xpp3-");
        urls[16] = resolveURL("/lib/xstream-1.1.3.jar");
        urls[17] = resolveURL("/bin/client.jar");
        urls[18] = resolveURL("/bin/deployer.jar");
        urls[19] = resolveURL("/bin/shutdown.jar");
        urls[20] = resolveURL("/bin/upgrade.jar");
        //urls[0] = resolveURL("/");
        JarFileClassLoader customLoader = new JarFileClassLoader(new Artifact( XrcpActivator.PLUGIN_ID, "", "", ""), urls, this.getClass().getClassLoader(), true, new String[0], new String[0]);
        try {
            Class mainClass = customLoader.loadClass ("org.apache.geronimo.system.main.Daemon");
            Method m = mainClass.getMethod("main", new Class[]{String[].class});
            m.invoke(null, new Object[]{new String[0]});
        } catch (Exception e) {
            // TODO Auto-generated catch block
