To call methods inside the same application is possible to use RMI ?

Question

hello,
What I should like to know is if RMI can easily be used to implement comunication (calling methods) inside classes that are part of the one same application... This should be a restrict case to use RMI...
The reason to do it come from the need to use the instance of a class knonwing it only as Object... This can be good to do if some code is used for general pupose in many different contexts.
In this case you can pass to the "server class" a parameter 'o' of type Object (all the classes extend Object) of the "customer class" to get back informations if some elaboration happen inside the "server class"...
This purpose is generally implemented with event listeners, but perhaps it could be done easily using RMI too (I dont know it...).
Using RMI in this simple situation, don't should require anything of complicate (stub, .... mashalling parametres....) to have the reference to method of the "customer class" to call. The "server class" already recives a reference of the "customer class" how parameter of type Object, and the mame of the method too.
I propose a simple thoeric example to explain really what I said before:
Class Server {
    String methodName;
    Object obj;
    pubic Server( Oject o , String metName){  // constructor
        obj = o;
        methodName = metName;
        // some thing is done and, at last, the method callbakMethod() is executed
        callbakMethod();
    }// constructor
    public void callbakMethod(){ // this method have the purpose to call customerMethod()
          Class c = owner.getClass();                            
          Method m = null;
              try {
                      m = c.getMethod("callBackMethod",null);     
                     * // (1)
                      // I think that here we could have the possibility to call
                      // the method  customerMethod() belonging to class Customer..
                      // I don't know if it possible and  ...  (and if it is possible) I am not able to do it*
    }// callbakMethod()
}  // class Server
Class Custmer{
    public Customer() { // constructor
          Server s = new Server (this, "customerMethod");
    } // constructor
    customerMethod() {    // I would this method is called from class Server
        // do some thing.....
    }  //customerMethod
}  // class CustomerMy ask is: it is possible to call customerMethod() from the Server class ?...
If the aswer is yes, I wold know the sintax to use to do it, please.
thank you

RMI doesn't help you in the slightest here. You can just realize it all using local method invocation. All RMI does is to make that remote. If the objects aren't remote there is no point.
