How to modify the JNDI names?

[K Kiran Kumar]

Hi,

I am using Eclipse+WAS 7 to develop my application. I have an EAR, which has a web application module and an EJB module.
I am able to access my EJB methods using the below client code. This code is from my web application.

My Client to access EJB methods:

public void callEjbMeth()
{
        String initialContextFactory = "com.ibm.websphere.naming.WsnInitialContextFactory";   
        String providerUrl = "corbaloc:iiop:localhost:2809";   
        Hashtable<String, String> environment = new Hashtable<String, String>();   
        environment.put(Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);   
        environment.put(Context.PROVIDER_URL, providerUrl);   
        try 
        {   
            Context ctx = new InitialContext (environment);   

            StateLessBeanLocal local = (StateLessBeanLocal) ctx.lookup("ejblocal:a.b.ie.StateLessBeanLocal");               
            System.out.println(local.getLocal());   

            StateLessBeanRemote remote = (StateLessBeanRemote) ctx.lookup("a.b.ie.StateLessBeanRemote");   
            System.out.println(remote.getRemote());
        } 
        catch (NamingException e)
        {   
            e.printStackTrace();   
        }  
}

Local interface:

@Local
public interface StateLessBeanLocal 
{
       public String getLocal();
}

Remote interface:

@Remote
public interface StateLessBeanRemote 
{
       public String getRemote();
}

EJB Bean:

@Stateless
public class StateLessBean implements StateLessBeanRemote, StateLessBeanLocal 
{
	@Override
	public String getRemote() 
                {
	           return "This is Remote Interface Method RRRRR";
	}

	@Override
	public String getLocal() 
                {
	           return "This is Local Interface Method LLLLL";
	}
}

I learned that I am accessing the default JNDI name of the EJB.
Could someone please let me know how/where I can customize the JNDI names to access the EJB bean methods so that I can access the bean methods using
ctx.lookup("xx/yyl"); instead of ctx.lookup("ejblocal:a.b.ie.StateLessBeanLocal");

Regards,
Kiran.

You can put the default name ejblocal:a.b.ie.StateLessBeanLocal to a property file and refer the service as a shorter name like xx.yyl.

In case your ejb changes, just update the property file without changing the code.

[James Boswell]

Try this for your stateless bean:

@Stateless(name = "foo", mappedName="foo")

You should then be able to lookup your bean using "foo".

Note, a downside to this is that it makes your code less portable.

Hi Kevin - Thank you for the response. However, I am looking for the name change as James Suggested.

James - Thanks a lot for your response. I tried out your suggestion. However, I get NameNotFoundException.
I used
StateLessBeanLocal local = (StateLessBeanLocal) ctx.lookup("foo"); in my client code and
@Stateless(name = "foo", mappedName="foo") in my Bean class

Please let me know if I am missing anything here.

Regards,
Kiran.

Hi,

I found the solution. Search for the file ibm-ejb-jar-bnd.xml (should be in ejbModule/META-INF/). Keep an entry in the file.
Example:
<session name="xxxServiceClass" simple-binding-name="ejb/abcd">
<resource-ref name="datasources" binding-name="datasource JNDI name"/> <! This is not mandatory-->
</session>

Kiran.
