Yet Another Remote Interface Lookup on glassfish problem :)

[William Bellia]

Hello all,

I have been going around lots of forums to figure out how to call a Remote interface in glassfish 3.1.

I have the following:

Stateless Bean:

package p1;

import javax.ejb.Stateless;

/**
 * Session Bean implementation class XbajtBean
 */
@Stateless(name="XbajtBean", mappedName ="XbajtBean")
public class XbajtBean implements XbajtBeanRemote, XbajtBeanLocal {

	public String getHelloWorld(){
		return "Hello World!";
	}
	
    public XbajtBean() {
        
    }
}
    

Remote Intf:

    
package p1;
import javax.ejb.Remote;

@Remote
public interface XbajtBeanRemote {
	public String getHelloWorld();
}

Then, in a different package in eclipse I have the following client, which happens to be a Stateless Bean as well. Basically, I need this 'client' to reside in the same application server, but in a different package:

  
 package p2;

import javax.ejb.Stateless;
import javax.naming.InitialContext;


@Stateless
public class XbajtCaller  {
	
	public String getResult(){
		
		try {
			XbajtBeanRemote x = (XbajtBeanRemote)new InitialContext().lookup("java:global/p1/XbajtBean!p1.XbajtBeanRemote");
			return x.getHelloWorld();
		} catch (Exception e) {
			e.printStackTrace();
			return e.getMessage();
		}

		
	}
}
 

Whenever I call the client via a web service, which resides in the same package as the client (i.e p2 ) I am getting the following error:

<return>Lookup failed for 'java:global/p1/XbajtBean!p1.XbajtBeanRemote' in SerialContext </return>


Also,
note that when I make a jndi-list lookup on glassfish, I get the following:

java:global: com.sun.enterprise.naming.impl.TransientContext
p1: com.sun.enterprise.naming.impl.TransientContext

so, the JNDI name DOES exist, yet, glassfish is not finding it whenever a call is issued by the cient, which happens to be on the same app server, just a different package.
( I have tried using local interfaces, and still no avail )

Your help would be really apreciated, since I have been pondering on this for days.

Regards,

William, checkout this page, it contains the syntax to find the JNDI name of beans...

Thanks Ankit for the reply.

However, p1 & p2 are totally different applications, therefore I have to use the java:global notation.
Moreover, my aim is to eventually call the Remote Interface from another remote application server,
but if I am unable to call remote interfaces within the same app server, then I reckon Im gonna hava a problem with that:)

Anyway, I did some further research and by doing the asadmin list-jndi-entries command I get the following:


java:global: com.sun.enterprise.naming.impl.TransientContext
com.sun.enterprise.container.common.spi.util.InjectionManager: com.sun.enterprise.container.common.impl.util.InjectionManagerImpl
jdbc: com.sun.enterprise.naming.impl.TransientContext
UserTransaction: com.sun.enterprise.transaction.TransactionNamingProxy$UserTransactionProxy
ejb: com.sun.enterprise.naming.impl.TransientContext
p1: com.sun.enterprise.naming.impl.TransientContext

So p1 is listed in the JNDI dir of my Glassfish.
In fact, when I perform

 ctx.lookup("p1"); 

or

 ctx.lookup("java:global/p1"); 

the program doesn't complain.

Also, further to that, by doing asadmin list-jndi-entries --context p1 I get the following:


XbajtBean__3_x_Internal_RemoteBusinessHome__: javax.naming.Reference
XbajtBean: javax.naming.Reference
XbajtBean#p1.XbajtBeanRemote: javax.naming.Reference


So, it seems my Bean and its Remote Interface are also listed in the JNDI dir under p1.

Yet, whenever I make a lookup call

 ctx.lookup("java:global/p1/XbajtBean"); 

or

 ctx.lookup("java:global/p1/XbajtBeanRemote"); 

etc,
I would get a Lookup Failed in Serial Context Exception.

Any further help would be greatly appreciated!

Thanks a lot
Will

From your jndi output:

XbajtBean#p1.XbajtBeanRemote

And your code:

XbajtBeanRemote x = (XbajtBeanRemote)new InitialContext().lookup("java:global/p1/XbajtBean!p1.XbajtBeanRemote");

Shouldn't it be:

XbajtBeanRemote x = (XbajtBeanRemote)new InitialContext().lookup("java:global/p1/XbajtBean#p1.XbajtBeanRemote");  

Notice the # instead of !

Which by the way, is contrary to what EJB3.1 global jndi name syntax mandates.

[William Bellia]

Thanks Jaikiran for the reply.

Yes, I did try that too,
and still getting the Lookup Failed exception:

java.lang.String : "Lookup failed for 'java:global/p1/XbajtBean#p1.XbajtBeanRemote' in SerialContext "

Thanks,
Will

Can you post the entire exception stacktrace?

[William Bellia]

Sure. Here it goes:
(Please note that the calling remote client consists of:
p2.XbajtWS which is a simple webservice which calls p2.XbajtCaller. XbajtCaller is basically the client stateless bean invoking the initial lookup)

When you deploy an artifact (for instance an ejb-jar module), Glassfish prints in the server.log file the portable JNDI namess and non portable JNDI names. Refer to this names if you want to be sure on the right name of your component.

Good luck,

Pierluigi
