I deploy a stateless session bean in a remote machine.
I can access the session bean at the same machine from a stand-alone client.
But I couldn't access the session bean from another machie's stand-alone client. Where do I set the session bean's ip address and service port number and how?
Thanks for your help.

Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, <<vendorspecific classname>>);
p.put(Context.PROVIDER_URL, <<url for the jndi lookup>>);
// vendor specific properties
InitialContext ctx = new InitialContext(p);
The actual properties and their values you need depend on the applicationserver you're talking to.
Each vendor (and possibly version) has its own peculiarities.
Thanks for your reply. :)
I use the Sun Application Server and tried like below.
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://192.168.68.8:3700");
InitialContext ctx = new InitialContext(env);
MyHello myHello = (MyHello) ctx.lookup("MyHelloEJB");
But I got an error like this...

Was the context factory name wrong?
you probably have an incorrect InitialContextFactory as well. That class is completely unknown to me (and I can't find it in the SJSAS client libraries).
see: http://blogs.sun.com/dadelhardt/entry/standalone_iiop_clients_with_glassfish
https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html#StandaloneRemoteEJB (which I don't all agree with. IMO you should use a Properties object when creating the IC but populate it from a file rather than hardcoding the properties in your code.
I set the InitialContext properties like below
env.put("org.omg.CORBA.ORBInitialHost", "host-ip-address");
env.put("org.omg.CORBA.ORBInitialPort", "3700");
It works well at the same machine with the sssion bean.
But in the different machine I got an error ...

It looks like the client tried to connect the local machine.
It means it does not work the setting of the InitialContext properties
in the client's code.
Have any idea?
