Hi Martin,
I am trying to do something similar and got the same exception.
java.lang.ClassCastException
     at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:293)
     at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:134)
     at com.sap.ip.bi.sdk.datasource.beans.TestJ2EE.getSystems(TestJ2EE.java:124)
     at com.sap.ip.bi.sdk.datasource.beans.TestJ2EE.<init>(TestJ2EE.java:67)
     at com.sap.ip.bi.sdk.datasource.beans.TestJ2EE.main(TestJ2EE.java:146)
The code snippet:
Properties props = new Properties();
          props.put(Context.INITIAL_CONTEXT_FACTORY,
                    "com.sap.engine.services.jndi.InitialContextFactoryImpl");
          props.put(Context.PROVIDER_URL, "localhost:50004");
          props.put(Context.SECURITY_PRINCIPAL, "Administrator");
          props.put(Context.SECURITY_CREDENTIALS, "");
          try {
               Context ctx = new InitialContext(props);
               Object obj = ctx.lookup("BI_SDK_CAF");
               IBI_CAF_Home boxHome = (IBI_CAF_Home) PortableRemoteObject.narrow(obj,
                         IBI_CAF_Home.class);
               BI_CAF_Bean bean = (BI_CAF_Bean) boxHome.create();
          } catch (Exception e1) {
               // TODO Auto-generated catch block
               e1.printStackTrace();
I tried doing the "get client jar" and putting it in the classpath but that did not work.
Am I missing something else?
