Portable JNDI Syntax lookup for EJB on Glassfish

由 自作多情 提交于 2019-11-29 13:02:28

Why is the invocation of the bean without "java:" or anything like that?

success:

thufir@dur:~$ 
thufir@dur:~$ glassfish-4.1/glassfish/bin/asadmin list-applications
Nothing to list.
No applications are deployed to this target server.
Command list-applications executed successfully.

thufir@dur:~$ glassfish-4.1/glassfish/bin/asadmin deploy NetBeansProjects/HelloEAR/dist/HelloEAR.ear

thufir@dur:~$ 
thufir@dur:~$ glassfish-4.1/glassfish/bin/asadmin list-applications

hello world
thufir@dur:~$ 
thufir@dur:~$

client code:

package net.bounceme.dur.jndi;

import greetings.GreetingsBeanRemote;
import java.util.logging.Logger;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class RemoteJNDI {

    private static final Logger log = Logger.getLogger(RemoteJNDI.class.getName());

    public static void main(String... args) {
        try {
            InitialContext ctx = new InitialContext();
//            Object obj = ctx.lookup("java:global/HelloEAR/HelloEAR-ejb/greetings.GreetingsBeanRemote");
            Object obj = ctx.lookup("greetings.GreetingsBeanRemote");
            GreetingsBeanRemote gbr = (GreetingsBeanRemote) obj;
            System.out.println(gbr.hi());
        } catch (NamingException ex) {
            ex.printStackTrace();
        }
    }

}

ejb:

package greetings;

import javax.ejb.Stateless;

@Stateless
public class GreetingsBean implements GreetingsBeanRemote {

    @Override
    public String hi() {
        return "hello world";
    }

    @Override

        return "bye";
    }

}

interface:

package greetings;

@Remote
public interface GreetingsBeanRemote {

    public String hi();

    public String bye();
}

If you are using Maven as well then check if "-1.0-SNAPSHOT" (or other version/as per your app) is attached at the end of the application-ejb file name as "application-ejb-1.0-SNAPSHOT", The full name would be "java:global/application-ear/application-ejb-1.0-SNAPSHOT/fileName"
