Naming.list("rmi://localhost:1099"); does not work

[thoste]

From a java client class I tried to find out all currently
offered rmi servers (server objects) by coding:

String[] objlist = Naming.list("rmi://localhost:1099");

But this yields the exception shown at the bottom of this posting.
Why?

How do I list otherwise all objects?

Do I have to setup JBoss for this "pure" (=not EJB) RMI usage?
Do I have to include some special jars in the client app CLASSPATH?
With an external rmiregistry all works fine.

rmi: is not a valid jndi protocol for the jboss naming service. The string should be "jnp://localhost:1099"

Changing to "jnp" does NOT solve the problem.
I got now the following exception:

MyClient exception: invalid URL scheme: jnp://localhost:1099/
java.net.MalformedURLException: invalid URL scheme: jnp://localhost:1099/

Yes, I put %JBOSS_HOME%/client/jnp-client.jar in the CLASSPATH.

The full code is:

public static void main(String[] args ) {

// Create and install a security manager
/*
if (System.getSecurityManager() == null) {
System.setSecurityManager(new RMISecurityManager()); }
*/
try {
String[] objlist = null;
objlist = Naming.list("jnp://localhost:1099/");
if (0 < objlist.length) {
System.out.println(" Available RMI objects (after rebind) using external Registry:");
int i = 0;
while(i < objlist.length) {
System.out.println(" - Object[" + i + "]="+ objlist);
i++; } }
} catch(......) { ... }

What are you trying to achieve? Why aren't you using JNDI? Are you still following a tutorial for a different application server?

Oh, your using the rmi registry Naming.list, not the jndi Context.list as I thought. JBoss does not implement an rmi registry. Use jndi.
