Glassfish v3 / JNDI entry cannot be found problems!
- by REMP
I've been having problems trying to call an EJB's method from a Java Application Client.
Here is the code.
EJB Remote Interface
package com.test;
import javax.ejb.Remote;
@Remote
public interface HelloBeanRemote {
public String sayHello();
}
EJB
package com.test;
import javax.ejb.Stateless;
@Stateless (name="HelloBeanExample" , mappedName="ejb/HelloBean")
public class HelloBean implements HelloBeanRemote {
@Override
public String sayHello(){
return "hola";
}
}
Main class (another project)
import com.test.HelloBeanRemote;
import javax.naming.Context;
import javax.naming.InitialContext;
public class Main {
public void runTest()throws Exception{
Context ctx = new InitialContext();
HelloBeanRemote bean = (HelloBeanRemote)ctx.lookup("java:global/Test/HelloBeanExample!com.test.HelloBeanRemote");
System.out.println(bean.sayHello());
}
public static void main(String[] args)throws Exception {
Main main = new Main();
main.runTest();
}
}
Well, what is my problem? JNDI entry for this EJB cannot be found!

I've trying with different JNDI entries but nothing works (I got this entries from NetBeans console):
INFO: Portable JNDI names for EJB HelloBeanExample : [java:global/Test/HelloBeanExample, java:global/Test/HelloBeanExample!com.test.HelloBeanRemote]
INFO: Glassfish-specific (Non-portable) JNDI names for EJB HelloBeanExample : [ejb/HelloBean, ejb/HelloBean#com.test.HelloBeanRemote]
So I tried with the following entries but I got the same exception :
java:global/Test/HelloBeanExample
java:global/Test/HelloBeanExample!com.test.HelloBeanRemote
ejb/HelloBean
ejb/HelloBean#com.test.HelloBeanRemote
I'm using Netbeans 6.8 and Glassfish v3!
