Hi everyone, if you could help me with this I would be forever grateful! I've
exhausted searching on the internet, and I've been through the trailblazer 3
times (but it focuses on accessing a local bean, rather than remote)
I'm getting a NameNotFoundException that has nothing to do w/ it not being
bound. Looking in the JNDI, the name exists, and, according to the
trailblazer, I'm accessing it correctly.
I downloaded JBoss AS 4.0.4.CR2 and installed the EJB 3.0 w/ Clustering.
The strangest part is that the error occurs no matter what name you put into
the ctx.lookup() method. So, if it doesn't matter if I pass
"HelloWorldBean/remote" or "JBossRocks" as a parameter to lookup(), I still get
| javax.naming.NameNotFoundException: HelloWorldBean/remote.
|
I would really appreciate any help I can get ... thanks!! The details are
below:
Here's the error:

Here's my remote interface:
public interface HelloWorld {
| public String getHelloWorldString(String reverseThis);
| }
Here's my stateless bean:
import javax.ejb.Remote;
| import javax.ejb.Stateless;
|
| import org.jboss.annotation.ejb.RemoteBinding;
|
| @Stateless
| @Remote ({HelloWorld.class})
| @RemoteBinding (jndiBinding="HelloWorld")
| public class HelloWorldBean implements HelloWorld
| {
| public String getHelloWorldString(String reverseThis) {
| return reverseThis + "Back";
| }
| }
This is JBoss showing the bean being deployed:
