Calling a RMI Server from a Servlet running under Tomcat

Good evening Everyone,

I've got a slightly off the subject question.  Is it possible to call a RMI
Server class from a servlet?  I'm sorry if this is a stupid question.  I've
started the switch from Visual Basic/ASP to Java (3 weeks ago) and would
like some input on this before I set out on the journey :).  Thanks in
advance.

Jeremy,
This is no problem

here's an example from our code


   /**
    * Establishes a connection to the remote Subscription Manager.
    *
    * @param subscriptionManagerURL The URL specifying the location of
the remote subscription Manager
    *
    **/
    protected boolean initSubscriptionManager(String
subscriptionManagerURL)
    throws ServletException
    {
	boolean rv = false;

        try {
		_remoteSM =
(elsme.subscription.SubscriptionManager)Naming.lookup(subscriptionManagerURL
);
		if (_remoteSM != null) {
			_remoteSM.init();
			rv = true;
		}
	} catch (RemoteException ex) {
		Log.stacktrace("initSubscriptionManager: remoteException", ex);
	} catch (Exception ex) {
        	Log.stacktrace("initSubscriptionManager", ex);
        }
        return rv;
    }

where subscriptionManagerURL is something like:

"rmi://localhost:1099/subscriptionman"

Hope this helps,

Duncan
