RMI Problemer, ClassNotFoundException

Hejsa eksperter,

Jeg sidder og er ved at forsøge på at få noget RMI til at fungere.... jeg HAR gjort følgende...

Skrevet et interface-indeholdende alle de metoder der skal kunne "fjern"-kaldes, og ladet dette implementere interfacet Remote...

Derefter har jeg lavet en implementation af interfacet, sat klassen til at nedarve fra UnicastRemoteObject og ladet den smide en masse exceptions, etc...

Så compiler jeg "skidtet" med javac.exe, og derefter danner jeg _stub-filer med rmic.exe,. Så skal jeg til at binde-skidtet på RMIregistry (og teste om det har fungeret)...

Dette gør jeg ved at starte RMIREGISTRY, og derefter eksekvere følgende kode-stump...:

String[] bindings = new java.lang.String[0];
        try {
            Naming.rebind("ost", new CommunicationHandlerImpl(3));
            bindings = Naming.list("");
        } catch (RemoteException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        } catch (MalformedURLException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }
        for (int i =0;i<bindings.length; i++) {
            System.out.println(bindings[i]);
        }

Men nu får jeg denne "ClassNotFoundException", også selvom mit IDE har sat enviroment-variabler (classpath, etc.) korrekt op... Jeg er MEGET forvirret...
