whats wrong with this client ?

[Sanju Thomas]

My JBoss client lookup return me org.jnp.interfaces.NamingContext type instead of my Bean remote type, I could not figure out anything wrong with the client. Please have a look.

Remote Interface

   

package mine.test.ejb;

import javax.ejb.Remote;

@Remote
public interface IBean {

	public void businessMethod();
}

Bean Class

   

package mine.test.ejb;

import javax.ejb.Stateless;
import javax.interceptor.AroundInvoke;
import javax.interceptor.InvocationContext;

import org.jboss.ejb3.annotation.RemoteBinding;

@Stateless
@RemoteBinding(jndiBinding="MyBean")

public class MyBean implements IBean{

	
	public void businessMethod() 
	{
		System.out.println("Business Method");
		
	}
	
	@AroundInvoke
	public Object interceptorMethod(InvocationContext ie) throws Exception
	{
		System.out.println("interceptorMethod is called");
		return ie.proceed();
	}

}

Client Class

  
package mine.test.ejb.client;

import java.util.Properties;
import javax.naming.*;

import mine.test.ejb.*;

public class EjbClient 
{
	
	public static void main(String args[]) throws NamingException
	{
		Properties properties = new Properties();			
		properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");		
		properties.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
		properties.put(Context.PROVIDER_URL, "jnp://localhost:1099");
		
		IBean ibean = (IBean)new InitialContext(properties).lookup("MyBean");

		ibean.businessMethod();
		
		
		
	}

}

Exception on the invocation of client. The loojup return me a type of org.jnp.interfaces.NamingContext, it shoud have been my remote type.

Exception in thread "main" java.lang.ClassCastException: org.jnp.interfaces.NamingContext
at mine.test.ejb.client.EjbClient.main(EjbClient.java:18)

Which version of JBoss AS?

Use JNDIView to determine the exact name to which the EJB was bound. In AS 5.x, the name will show in the console log.

Hi Peter, Thanks for the reply. I am using jboss-5.0.1.GA.

[Sanju Thomas]

Thanks Peter its worked. This is what shown in the console.

"/remote" with the bean name is something new I think. It was not there in JBoss 4, isn't it ?

[Jaikiran Pai]

 import org.jboss.ejb3.annotation.RemoteBinding;  
   
 @Stateless  
 @RemoteBinding(jndiBinding="MyBean")  

Based on this code, the remote interface of the bean should have been bound to "MyBean"

MyBean/remote - EJB3.x Default Remote Business Interface

Looks wrong. It should not have bound to MyBean/remote since you have overridden it in the code. Are you sure the jar that you are deploying, contains exactly this piece of code? And do you have any ejb-jar.xml or jboss.xml for this EJB app?

[Sanju Thomas]

you are correct, I removed the jndi binding code from the bean class.
