applets

Hello, I created a simple Applet using JApplet and everything seems to work fine but as soon i create an object of my userdefined class named ChatUser in my applet, i get this error :-

SEVERE: java.lang.ClassNotFoundException: applet.ChatUser
        at com.sun.enterprise.loader.ASURLClassLoader.findClassData(ASURLClassLoader.java:713)

        at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351)
        at misc.ChatClient.run(ChatClient.java:43)

Any idea what can be wrong? It only happens when i create an object of any user defined class. Do i need to set some security settings or something? Please help :(
