RE: Applet Accessing RMI or TCP located on another server

The URL you are using to connect to the server doesn't match that indicated
by the exception.
 
By default, the tcp connector listens on port 3035.
The rmi connector listens on port 1099.
 
To connect using tcp:
    properties.put(Context.PROVIDER_URL, "tcp://localhost:3035/");
 
To connect using rmi:
    properties.put(Context.PROVIDER_URL, "rmi://localhost:1099/");
 
The configuration in openjms.xml for tcp:
  <TcpConfiguration port="3035"/>

The configuration in openjms.xml for rmi:
  <RmiConfiguration registryPort="1099"/>

Subject: [openjms-user] 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.
