Digging in JNDI

JNDI is a bit of a mystery for me...whenever I get an exception like:

javax.naming.NameNotFoundException: While trying to look up comp/env/jms/CF1 in /app/webapp/rocAdmin/1482669104.; remaining name "comp/env/jms/CF1" at weblogic.jndi.internal.BasicNamingNode.newNameNotFoundException(BasicNamingNode.java:1180) at weblogic.jndi.internal.ApplicationNamingNode.lookup(ApplicationNamingNode.java:143) at weblogic.jndi.internal.WLEventContextImpl.lookup(WLEventContextImpl.java:253) at weblogic.jndi.internal.WLContextImpl.lookup(WLContextImpl.java:426) at weblogic.jndi.factories.java.ReadOnlyContextWrapper.lookup(ReadOnlyContextWrapper.java:45) at weblogic.jndi.internal.AbstractURLContext.lookup(AbstractURLContext.java:130) at javax.naming.InitialContext.lookup(InitialContext.java:411) ...

I scratch my head ... So I wrote some code to dump the content of the InitialContext (it runs in a EJB timer to avoid having to create a client:

package com.pierre;

import javax.ejb.Schedule;
import javax.ejb.Stateless;
import javax.ejb.Timer;
import javax.naming.Binding;
import javax.naming.InitialContext;
import javax.naming.NamingEnumeration;
import javax.naming.NamingException;

@Stateless
public class PVTimer {

    /**
     * Default constructor.
     */
    public PVTimer() {
 // TODO Auto-generated constructor stub
    }

    @SuppressWarnings("unused")
    @Schedule(second = "*/10", minute = "*", hour = "*", dayOfWeek = "*", dayOfMonth = "*", month = "*", year = "*", info = "MyTimer")
    private void scheduledTimeout(final Timer t) {
 System.out.println("@Schedule called at: " + new java.util.Date());
 try {
     System.out.println();
     InitialContext ic = new InitialContext();
     NamingEnumeration names = ic.listBindings("");
     printNames(names, "all");
     NamingEnumeration jms = ic.listBindings("jms");
     printNames(jms, "jms");
     System.out.println();
 } catch (Throwable t1) {
     t1.printStackTrace();
 }

    }

    private void printNames(NamingEnumeration names, String title)
     throws NamingException {
 int count = 1;
 while (names.hasMore()) {
     Binding next = names.next();
     System.out.println(title + " " + count + " ToString=" + next.toString() + " Name=" + next.getName() + " Classname=" + next.getClassName() + " getObject=" + next.getObject());
     count++;
 }
    }
}

and this is the result:

(I have a stateless EJB "PVStateless" in the same module , implementing a PVStatelessRemote interface.... plus a JMS queue "PVQueue" with JNDI name "jms/PVQueue" and a JMS CF "PVConnectionFactory" with JNDI name "jms/PVConnectionFactory"....

Interesting javadoc http://docs.oracle.com/javase/7/docs/api/javax/naming/Binding.html and http://docs.oracle.com/javase/7/docs/api/javax/naming/InitialContext.html
