Other blindness * Not reading the spec to understand what is guaranteed behaviour and avoid writing non-portable code (practically nothing is guaranteed if you have active listeners on a queue you are trying to browse concurrently) * Using selectors on Queues (I am bored of repeating myself already) * etc. View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3912545#3912545 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3912545 --- This SF.net email is sponsored by: Splunk Inc.

Another one. MDB in CLIENT_ACK Explain how you use client acknowledgement with an MDB? There is no such configuaration!

And the real FAQ of this thread is browsing scheduled messages and claiming a BUG If you can show me where in the spec it even mentioned scheduled messages and their behavour I will gladly concede this is a bug. Going back to the LGPL comment. The code for scheduled messages for contributed by a non JBoss employee. He obviously didn't have a need for browsing scheduled messages since he didn't add code for it. So your choices are simple; * Add the code yourself and keep it to yourself * Add the code yourself and contribute it back for others to use * Raise a feature request and wait for somebody else to do it for you View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3912551#3912551 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3912551 --- This SF.net email is sponsored by: Splunk Inc.

And the final FAQ is CLIENT_ACK and browsers. If you receive under CLIENT_ACK, the message belongs to session NOT the QUEUE. So it is invisible to any browser.

Hi upankar
I hgave tried the following code in BasicQueue.java and it seems to work. Not
sure of the implications in a clustered environment. Still to add some thread
safe locks if necessary.
|
|public SpyMessage[] browse(String selector) throws JMSException
|{
| if (selector == null)
| {
| SpyMessage list[];
| synchronized (messages)
| {
| list = new SpyMessage[messages.size() + events.size()];
| Iterator iter = messages.iterator();
|
| int i = 0;
| for (; iter.hasNext(); i++)
|list =
| ((MessageReference)
iter.next()).getMessageForDelivery();
|
| Iterator eventsIter = events.keySet().iterator();
| for(; eventsIter.hasNext(); i++) {
| list =
| ((MessageReference)
|
eventsIter.next()).getMessageForDelivery();
| }
| }
| return list;
| }
| else
| {
| Selector s = new Selector(selector);
| LinkedList selection = new LinkedList();
|
| synchronized (messages)
| {
| Iterator i = messages.iterator();
| while (i.hasNext())
| {
|MessageReference m = (MessageReference) i.next();
|if (s.test(m.getHeaders()))
| selection.add(m.getMessageForDelivery());
| }
| }
|
| SpyMessage list[];
| list = new SpyMessage[selection.size()];
| list = (SpyMessage[]) selection.toArray(list);
| return list;
| }
|}

Thanks for your answer. I do appreciate. But i have some apprehensions modifying the source code - I think Jboss controlls all code changes , patch etc, and doing on our own probably might not be legal. Hence, we have implemented a work-around. When we need re-delivery, we add the message back to queue as a new new one with a property called STATUS and value as REDELIVER. Another property called REDELIVERY_TIME is set which is equal to = current time (in milliseconds) + redelivery delay. Then, we start a sychronous consumer thread which runs every sometime and looks for items with status RETRY and REDELIVERY_TIME = current time ( uses message selector). The main MDB is modified to use a message selector for items with status PENDING. This way, MDB doesnt get RETRY status items.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Queue Messages are not listed in QueueBrowser when in 'w
Hello upankar
I was the one who posted a similar question last month and after much searching
I was unable to find a solution to my problem. I was told that there might be
a patch, but I am unable to find it. Not sure if you have to have a
subscription to access it. I did find a reference to a post made a couple of
years ago, but have not seen any solutions. I have been thinking about
creating my own patch, but have been waiting to see if others have a better
solution.
I have been thinking about adding code to the browse method of the BasicQueue.
public SpyMessage[] browse(String selector) throws JMSException {
.
.
.
SpyMessage [] list
for (Iterator i = events.keySet().iterator(); i.hasNext(); ) {
MessageReference message = (MessageReference)iter.next();
list[XXX] = message.hardReference; // may need to do a clone here
}
return list;
}
Some feedback would be great.
All I havve to do now is to figure out how to compille up my changes.
Thanks
Shafiek

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Queue Messages are not listed in QueueBrowser when in 'w
Sorry.. but i still dont find the answer in the help link.. My specific question is Is there a way to view the scheduled messages ( i.e. scheduled for redelivery) ? Because i could see that anything that is not acked by the MDB in CLIENT_ACK mode increases the scheduledMessageCount by 1 while decrementing the QueueDepth by 1. And since standard queue browser is not picking up scheduled items when i attempt to browse the queue, is there any other way to view them ? Could you help point me to exact answer ?
