Applet Accessing RMI or TCP located on another server

I know there have many discussions about trying to get around the
firewall so the client can connect to the server.  However, I'm still
confused.

 

I created an applet that accesses the openJMS server with these
followings properties:

Hashtable properties = new Hashtable();

properties.put(Context.INITIAL_CONTEXT_FACTORY,

                "org.exolab.jms.jndi.InitialContextFactory");

properties.put(Context.PROVIDER_URL, "tcp://localhost:3035/");

....

// create the JNDI initial context.

context = new InitialContext(properties);

 

Now, the applet works if I open it from computer,
C:\java\jms\new_openJMS\web\anew\4newhtml.html.

However, when I run this page from my webserver at,
http://localhost:8084/new_openJMS/anew/4newhtml.html, I get the
following error:

 

javax.naming.CommunicationException: Failed to get registry service for
URL: tcp://localhost:1035/ [Root exception is
java.rmi.ConnectIOException: Failed to create connection; nested
exception is: 

org.exolab.jms.net.connector.ConnectException: Failed to connect to
localhost:1035]

I changed my URL to rmi://localhost:3035.  Again, the local copy of the
applet is able to connect to openJMS but the applet that is ran from my
web server doesn't work.

 

Here's my full stack trace:

I know the solution may involve signing the applet, but I don't know how
to do that.  Thanks, any help is appreciated.
