Help needed for an EJB (standalone) Application Client.

[holyfish]

Hi,

I'm setting my first steps with EJB (using the JBoss Application Server) in Eclipse.
Building a web-based application doesn't give any problems (there are plenty of good tutorials available) but making an (standalone) Application Client for my Beans gives a problem. Strangely enough not many tutorials handle that subject...

The problem is I don't know how to do a Bean lookup from my Java Application.
RandomBean just generates a random number.
Here is some code I found, though this gives an error (see below):

package randomclient;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import random.RandomRemote;
import random.RandomRemoteHome;

public class RandomClient
{
public static void main(String[] args) throws Exception
{
 Context initial = new InitialContext();
 Context env=(Context)initial.lookup("java:comp/env");
 Object obj=env.lookup("ejb/RandomBean");
 RandomRemoteHome home=(RandomRemoteHome)
 PortableRemoteObject.narrow(obj,RandomRemoteHome.class);
 RandomRemote b=home.create();
 System.out.println(b.random());
 }
}

This is the error I'm getting:

Exception in thread "main" javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
 at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)
 at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247)
 at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:284)
 at javax.naming.InitialContext.lookup(InitialContext.java:351)
 at Main.main(Main.java:15)

It has to do with the Lookup() function (probably wrong values there) but I have absolutely no idea what to fill in there.

Does someone have an idea please?

Thanks a lot in advance!

please do this to build the 'InitialContext" like

public static InitialContext getInitialContext()
{
Properties props=new Properties();
InitialContext jndiCtx=null;
try
{
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL,"jnp://localhost:1099");
props.put(Context.STATE_FACTORIES,"org.jboss.naming:org.jnp.interfaces");
jndiCtx=new InitialContext(props);
}
catch(Exception ex)
{}
return jndiCtx;
}

public static void main(String args[])
{
System.out.println("\nBegin TimerSessClient...\n");

try
{
InitialContext ctx=getInitialContext();
Object obj=ctx.lookup("kattabomman");
TimerSessHome home=(TimerSessHome)PortableRemoteObject.narrow(obj,TimerSessHome.class);
System.out.println("Creating TimerSess Bean\n");
TimerSess sess=home.create();........
................................
here TimerSess is remote interface of a sessionBean
TimerSessHome is home interface
you require client jars in class-path like jboss-client,jboss-j2ee,jnp-client etc
