[SOLVED] How to remove shared object in JME RMI

Hi

Do we need to remove shared object when the client service got removed ? If so, how ?

For example see

Simsilica/Examples/blob/91e9588955b398776142ef319482ae1660c0e035/sim-eth-es/src/main/java/example/net/client/GameSessionClientService.java#L138


    if( rmiService == null ) {
        throw new RuntimeException("GameSessionClientService requires RMI service");
    }
 
    // Register the session right away even though the 'state' of the connection
    // is that we are not actually in the game yet.  Because the server is managing
    // that state, it does no harm for us to register the callback early and this
    // way we avoid any case where the server might try to call it before we are 
    // fully ready. (ie: it's friendlier to async messaging)
    log.debug("Sharing session callback.");  
    rmiService.share(sessionCallback, GameSessionListener.class);
}
 
/**
 *  Called during connection setup once the server-side services have been initialized
 *  for this connection and any shared objects, etc. should be available.
 */   
@Override
public void start() {
    log.debug("start()");
    super.start();

it shares callback listener on initialize but never removes it on terminate.

Edit:

Suppose we have some services which we add them when player is in game session and remove them when he leaves the game session, but stays connected (logged in), and he might want to rejoin to game session again.

Why are you removing the client service?

Stuff should be cleaned up during normal connection termination but in general a lot of the services consider that once they are registered they will exist until the connection tears down.

Thanks that explains it.

Probably for no good reason , I thought I am supposed to add them when need them and remove them when not need.
