Portable way to list EJBeans on the app server

[Aravind Selvaraje]

Hi,

Is there a nice portable way to programatically list the EJBeans on the
server ?

I have the following piece of code that works under WebLogic but not under
WebSphere because of the narrowing mechanism stuff.

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


public class Dump{

  public static void main(String[] args) {
    try {
      Properties p = new Properties();
      p.put(Context.INITIAL_CONTEXT_FACTORY,
        "com.ibm.jndi.CosNaming.CNInitialContextFactory");
      p.put("java.naming.provider.url", "iiop://localhost:9019");

      Context ctx = new InitialContext(p);
      dumpEJBs(ctx);
    }
    catch (Exception e) {
      System.out.println("Error:\n" + e);
    }
  }

  private static void dumpEJBs(Context ctx) {
    try {
      NamingEnumeration enum = ctx.listBindings("");
      while (enum.hasMore()) {
        Binding binding = (Binding)enum.next();
        Object object = binding.getObject();

        System.out.println(">>> Debug Classname: " +
object.getClass().getName());

        if (object instanceof EJBHome)
          System.out.println("Classname: " + object.getClass().getName());
        }
        else if (object instanceof Context) {
          try {
            dumpEJBs((Context)object);
          }
          catch (Exception e) {
            System.out.println("Error: " + e);
          }
        }
      }
    }
    catch (NamingSecurityException nse) {
    }
    catch (SecurityException se) {
    }
    catch (Exception e) {
      System.out.println("Error: " + e);
    }
  }
}
