Try to get JDNI tree (NoClassDefFoundError: weblogic/jndi/Environment)

Question

hiya,
I try to get access to the jdni tree of a weblogic server (8.1). But I always get the exception:
java.lang.NoClassDefFoundError: weblogic/jndi/Environment
javax.faces.el.EvaluationException: java.lang.NoClassDefFoundError: weblogic/jndi/Environment
at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:102)
I added the weblogic.jar and the wlclient.jar. Is something still missing?
Here's a part of the Code, where the exception occurres:
private static InitialContext getContext(){
bq. InitialContext ctx = null; \\ Environment environment = new Environment(); /*ERROR*/ \\     environment.setInitialContextFactory(Environment.DEFAULT_INITIAL_CONTEXT_FACTORY); \\     environment.setProviderUrl(url); \\     environment.setSecurityPrincipal(username); \\     environment.setSecurityCredentials(password); \\     try { ctx = (InitialContext) environment.getInitialContext(); \\     } catch (NamingException e) { System.out.println(e.getMessage()); } \\     return ctx;
Hope that somebody can help me...
thanks,
traysa

hm... I'm not authorised to change something in the script.
is there no other way... ?
Here's the code from the edocs of weblogic 8.1. The Code is trying to retrieve the MBeanHome from an external Client:
public void action() {
          MBeanHome home = null;
          //domain variables
          String url = "t3://xxx";
          String username = "xxx";
          String password = "xxx";
          //Setting an initial context.
          try {
               Environment env = new Environment();
               env.setProviderUrl(url);
               env.setSecurityPrincipal(username);
               env.setSecurityCredentials(password);
               Context ctx = env.getInitialContext();
               //Retrieving the Administration MBeanHome interface
               home = (MBeanHome) ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
               result = "Got the Admin MBeanHome: " + home + " from the Admin server";
          } catch (Exception e) {
               System.out.println("Exception caught: " + e);
here's a short summary of problems I have:
1. Environment
Trying to get the initial context from the environment:
Environment env = new Environment();
env.setProviderUrl(url);
env.setSecurityPrincipal(username);
env.setSecurityCredentials(password);
Context ctx = env.getInitialContext();
exception:
java.lang.NoClassDefFoundError: weblogic/jndi/Environment
2. MBeanHome
instead of Environment, I'm using a Hashstable.
home = (MBeanHome) ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
The attempt to get the MBeanHome throws following exception:
java.lang.NoClassDefFoundError: weblogic/management/MBeanHome
I just don't understand why it doesn't work. Have I missed some settings?
I'm using JDK 1.5, Developing in Eclipse, added the libs weblogic.jar, wlclient.jar and rt.jar,...
thx
