Listing JMS Destinations ON a JNDI TREE

you might want to try the code snippet of listing contexts from any java code which is available while server is running.

Context ctx = new InitialContext();

NamingEnumeration list = ctx.list("");

while (list.hasMore()) {

NameClassPair nc = (NameClassPair) list.next();

System.out.println(nc);

}

Two points to take care

1. You might have to initialize intial context with your server specific jndi properties(if its not done already)

2. Once you get the context list , you can repeat this operation on any sub context that is printed to you ..which will effectively lead to navigation on the jndi tree

Dear Warrior,

I had managed to recursivly browse through the JNDI and get the hashtable which I require. Here is the sample.

/**

* Generates a Hashtable with JNDI name as key and Object type as value.

*

* @param jndiList - the hashtable to append to

* @param ctx- the context for which the bindings are to be listed

* @param path- the path to be listed under a context

*

* @since 0.1

*/

private static void listContext(Hashtable jndiList, Context ctx, String path) {

if (ctx == null) {

return;

}

try {

NamingEnumeration list = ctx.listBindings(path);

while (list.hasMore()) {

Binding item = (Binding) list.next();

String className = item.getClassName();

String name = item.getName();

if (name != null) {

if (name.equals("")) {

continue;

}

} else {

continue;

}

Object o = item.getObject();

if ((className != null) && (name != null) && (o != null)) {

if (o instanceof javax.naming.Context) {

listContext(jndiList, ctx, path + "/" + name);

} else {

jndiList.put(path + "/" + name, className);

}

}

}

} catch (NamingException ne) {

System.err.println(

"Caught NamingException <" + ne.getMessage() + "><"

+ ne.getExplanation() + "><" + ne.toString(true) + ">");

} catch (Exception e) {

System.err.println("Caught Exception <" + e.getMessage() + ">");

}

}

Hope this solves the problem.

Yes my friend,

listContext(jndiList, ctx, "jms");

And the output table is,

jms/queues/app/APP_QCF=com.ibm.mq.jms.MQQueueConnectionFactorycom.ibm.mq.jms.MQQueueConnectionFactory

jms/queues/app/APP.IN.Q.IE=com.ibm.mq.jms.MQQueuecom.ibm.mq.jms.MQQueue

jms/queues/app/APP.IN.Q.CD=com.ibm.mq.jms.MQQueuecom.ibm.mq.jms.MQQueue

jms/queues/app/APP.IN.Q.IO=com.ibm.mq.jms.MQQueuecom.ibm.mq.jms.MQQueue
