Greetings Gurus!

I am having difficulty referencing the DefaultDS from a
client running outside the JBoss JVM. Any advice or examples would be
greatly
appreciated. I am running JBoss version 4.0.5GA. I eventually want to
load
and use the datasource in the client application. For simplicity of
example,
I set up a default JBoss install. It seems that I do not have access
to anything in the java: context from outside the JBoss JVM. Are there
security constraints that need to be modified?

Here is my source code:

---

import java.util.*;
import javax.naming.*;

public class JNDI {

public static void main(String[] args) {
try {
Context ic = new InitialContext();

// Print the environment settings
System.out.println("Printing environment keys:");
Hashtable hash = ic.getEnvironment();
Enumeration keys = hash.keys();
while (keys.hasMoreElements()) {
Object key = keys.nextElement();
Object value = hash.get(key);
System.out.println(key + "=" + value);
}

// We can see several bindings, just not the ones we need
System.out.println();
System.out.println("Printing bindings in jmx:");
NamingEnumeration<Binding> b = ic.listBindings("jmx");
while ( b.hasMoreElements() ) {
Object key = b.nextElement();
System.out.println(key);
}

System.out.println();
System.out.println("Get the default datasource:");

// Both of the following lines choke:
// b = ic.listBindings("");
// Context compEnv = (Context) ic.lookup("java:/DefaultDS");
}
catch (Exception e) {
e.printStackTrace();
}
}
}

---

The first few lines of output look like:

Printing environment keys:
jnp.parsedName=
java.naming.factory.initial=org.jnp.interfaces.Nam ingContextFactory
java.naming.provider.url=localhost:1099
java.naming.factory.url.pkgs=org.jboss.namingrg. jnp.interfaces

Printing bindings in jmx:
invoker:
org.jnp.interfaces.NamingContextrg.jnp.interface s.NamingContext@a4e743
rmi:
org.jnp.interfaces.NamingContextrg.jnp.interface s.NamingContext@4aeb52

The "listBindings" call throws the following stack dump:

I am certain that the DefaultDS is up and running since the out of the
box
examples work, however they are all running inside JBoss. I have tried
many
many things to no avail.

I really want to use JBoss, and eventually lend my support to the
efforts
surrounding what appears to be an awesome project, but I am beginning
to
have doubts in my choice as I have been trying to get this to work for
some time. What am I doing wrong?

I am completely confused. Please advise.

Your help is greatly appreciated,
Randall

DataSources are local within the server - you can not share them
with client app.

If you create an entity bean you can access it remotely
from your client app.
