howto supplement pristine fan side surrogate remote object

i got small problem i can't figure out. i have server side marshalbyrefobject i'm perplexing hang pristine surrogate around fan side. here's setup:

public category clientprogram {
    open stationary vacant main( string[] args ) {
        itest exam = (itest)activator.getobject( typeof( itest ), "http://127.0.0.1:8765/test.rem" );
        exam = (itest)new myproxy( exam ).gettransparentproxy();
        test.foo();
    }
}

public category myproxy : realproxy {

    private marshalbyrefobject _object;

    open myproxy( itest pinstance )
        : base( pinstance.gettype() ) {
        _object = (marshalbyrefobject)pinstance;
    }

    open overrule imessage invoke( imessage msg ) {
        relapse remotingservices.executemessage( _object, (imethodcallmessage)msg );
    }
}

the problem remotingservices.executemethod, an difference thrown summary "executemessage called wholly internal context object.". anyone indicate out work correctly? i need inject formula before after slight calls remote objects. cheers!
