NameNotFoundException - ${j2ee.client} not bound

Question

Good day, all. I'm new to J2EE, so apologies up front if this is a brain-dead
question. I have done some searching around on the site, and have found similar
issues, but none which contain a working solution for me, as far as I can tell.
I'm attempting to write a J2EE client application using JBoss. I have a main function
which is attempting to look up entries from the server's Global JNDI context, and isn't
finding them.
My main():
package nameredacted;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import nameredacted.log.AccountingLog;
import nameredacted.log.AccountingLogFactory;
public class JobMain {
     private static final AccountingLog log = AccountingLogFactory.getAccountingLog(JobMain.class);
     public static void main(String[] args)
          try
               Context ctx = new InitialContext();
               // v--- Explosion occurs below: ---v
               String lookupName = (String)ctx.lookup("java:comp/env/name_space_root");
               Context globalCtx = (Context)ctx.lookup(lookupName); // I don't ever get here.
               if (log.isInfoEnabled())
                    log.info(null,"Loaded Global Context");
               System.out.println("Yay");
               System.out.println(globalCtx);
          catch (NamingException e2)
               log.warn("There was an error looking up the name_space_root:  " + e2);
               e2.printStackTrace();
}My jndi.properties file:

BUILD SUCCESSFULThanks in advance for your help: I think my monitor is beginning to bruise from repeated
head impacts...
Er, something.

I'm not familiar with the specifics of how the JBoss implementation requires that Application Client
components be executed so I'd recommend checking their documentation. There is often a
special command needed to run an Application Client within an Application Client container. It's
typically more than just configuring the client to bootstrap a particular naming provider.
For example, in the Java EE SDK, we have a special command called "appclient" that is used to
start an Applicaiton Client component. The Application Client container bootstraps the
correct naming provider, sets up the private component naming environment (java:comp/env),
handles any authentication, etc. You can find more information on the difference between
an Application Client and a "stand-alone java client" in our EJB FAQ :
