New to EJB3 -- Please help

[chensquare]

Hi all,

I'm new to EJB. I'm writing a toy EJB, and having problem running the client (bean can be deployed successfully in Eclipse) When running the client, it generates javax.naming.NameNotFoundException: HelloBean not bound.

Please help. THANKS A LOT!!!

my config:
IDE: Eclipse
JBOSS: 4.0.5

//INTERFACE:
package examples.session.stateless;
import javax.ejb.*;
public interface Hello {
public String hello() ; //throws java.rmi.RemoteException;
}


//BEAN CLASS
package examples.session.stateless;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.ejb.*;
@Stateless
@Remote(Hello.class)
public class HelloBean implements Hello {
public String hello () {
System.out.println("in hello()...");
return "Hello, World!";
}
}


EJB-JAR.XML
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar id="ejb-jar_ID" version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">
JBoss Hello World Application
<display-name>HelloBean</display-name>
<enterprise-beans>
<ejb-name>HelloBean</ejb-name>
</enterprise-beans>
</ejb-jar>



CLIENT
package examples.session.stateless;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;

public class HelloEJBClient {
public static void main( String [] args )
{
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1099");
env.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");

try
{
InitialContext ctx = new InitialContext(env);
Hello hello = (Hello) ctx.lookup( "HelloBean" );
System.out.println(hello.hello());
}
catch ( Exception e )
{
e.printStackTrace();
System.out.println( "Chen - Exception: " + e.getMessage() );
}
}
}

Look at the JMS console if and where the bean might have been deployed.

Yes, JMX-Console indicates that bean is deployed properly on the server. Anyone--please help. THANKS A MILLION !!

I'm just like you - new to EJB - and got exactly the same problem like you when I tried to disect EJB3Trail and create my own project...

However, then I downloaded the sample helloworld that this guy did: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037705#4037705

Then it worked!?!
I have not managed to find out the what was different with what I did yet... but it would be interesting to know!

AFAIK the default JNDI location should be:
EAR-FILE-BASE-NAME/EJB-CLASS-NAME/local

But it just fails to find my Stateless session bean with the error: EJB3Test not bound
(and the name of my ear file is EJB3Test.ear)

Thanks Kent. I will try the example that you suggested today.

It looks like my bean is deployed correctly, and the error is in my client code. I'm sure an experienced EJB programmer can spot my error immediately, I just don't know what else to try (none of the examples that I googled matches my code. I'm trying to follow the example in MasteringEJB3.0 book).
