2. Re: QueueBrowser not returning anything in Enumerator
tim.shaw Mar 11, 2008 6:30 AM (in response to tim.shaw)Please could you expand on this and define "delivered" and "client". By delivered is this the point when it reaches the onMessage method or when the message is fully removed from the database?
I stated in my text that by placing a breakpoint during processing within my IDE, the messages are 'visible' and it would be my understanding that these would be available to the QueueBrowser enumerator.
Also, within the JMX console the message count is not 0 which implies to me that the messages have not been fully delivered, but they are not being shown in the message listings.
Thanks for any further comment on this topic. -

tim.shaw Mar 25, 2008 6:30 AM (in response to tim.shaw)I presume you mean http://wiki.jboss.org/wiki/Wiki.jsp?page=JBMCantSeeMessages? Your suggestion for search returned nothing, so thanks for that.
The issue is that, when using messaging to distribute processing across the cluster, we would like to know when all the messages have been processed - implementing a fork/join in process-management terms.
I can understand that the queue is prefetched to the cluster members, and so the elements are unavailable to the QueueManager, and I can see that implementing the functionality required would involve querying each of the cluster members for it's state (in buffer, being handled etc), and that this may not be possible (or, rather, easy).
However, I would suggest that this is not an unusual scenario (fork/join is a pretty basic mechanism) and think that others would have a strategy to deal with this ... and was wondering if there were any suggestions?
All we are trying to do is solve a real world problem - a little less tersity would have been appreciated.
I will post a separate thread to try to get useful comments on this ... and maybe set up a wiki page for it?

No. Because that is about JBoss Messaging while this is the JBossMQ forum.
I mean listInProcessMessages which is in the JBossMQ documentation.

I'd be less terse if this wasn't an FAQ that still gets asked redundantly twice a month.
Of course you can't find the long version of the answer because redundant
questions like yours make the search unusable.
If you want to complain, then complain to yourself and people with the same
lazy attitude. -

Sorry, when you said 'in the wiki' I presumed you meant 'in the wiki'. Obviously my mistake.I'd be less terse if this wasn't an FAQ that still gets asked redundantly twice a month.
I suggest that if an FAQ continues to get asked, then the FAQ section is at fault. We finally found it by searching for 'InProcess' in the wiki. The actual title of the FAQ is 'There is always one more InProcess message than there should be' ... which is rather like expecting me to find it in a cupboard behind a door marked 'beware of the leopard'!Of course you can't find the long version of the answer because redundant
questions like yours make the search unusable.
Just quoting a correct search term, a URL or even a terse message saying it was covered in the FAQ would have been sufficient - but judging from your previous posts your patience and tolerance levels are rather below what I would expect from a professional spokesperson.If you want to complain, then complain to yourself and people with the same

That's just rude and unnecessary. I was politely (if slightly tongue-in-cheek) pointing out that you could have expended the same amount of effort giving a helpful answer.
I repeat my thanks from the earlier post.
Have a good day.

The FAQ is a WIKI. If you think it is wrong, misleading or hard to use,
you can fix it yourself. I've got no idea why you think it is wrong, you do.
I'm not psychic.

I have zero tolerance for people that pollute the search index with redundant
repeat questions especially when they then complain that they can't find anything.

At jboss.org I'm not an official spokesperson, I'm just another member
of the community answering questions for free.
I'm just one that posts LARTs to try to stop this forum
filling up with lazy/repeat questions making it impossible for other
members of the community to find where a question was actually answered.
Like I always say. If you want to be lazy use the newbies forum.
