Dynamic Topic/Queue Creation which survive server restarts

[edcurry]

Theres a few posts on this forum which deal with the dynamic creation of dynamic topic/queue using the JMX interface. Any queue/topic created in this manner will only live for the duration of the server life and will not survive a server restart.

In order to create a 'permanent' queue/topic we need to alter the jbossmq-service.xml and jbossmq-destinations-service.xml files.

Everything right so far ?

I need to be able to create and remove 'permanent' queue/topics. The most obvious way i can think of doing this is by adding some code to the server which edits the above files.

Now here comes the questions....

Has anyone already done this ?
Would anyone else find this usefull ?

i have a few ideas for implementation...
add a method to the JMX interface createPermanentQueue(...).
Alter the present JMX methods to edit the files...
Create a new bean to alter the files, this would avoid me having to jump into the JMX interface...

Im new to the open world so any advice would be great!

All the best,
Ed

Have a look at:
http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t=forums/ in this area, i also read a few newer posts which said that this was being worked on. This would save you having to write what your planning to.

I too am in need for this kind of functionality, Perhaps someone on this forum might know of the progress of this mbean persistence effort?

How to use the JMX interface to create the dynamic queue/topic? can u give me the java code? thanks

I have been creating queues dynamically by (ab)using the deployer of jboss. I just create *-service.xml files in the deploy directory that define the queue... Works for me.

Hmmm, is this a good strategy?

I would copy over a xxxx-service.xml to deploy dynamic queues/topic as well and have the deployer handle it.

You can also directly instantiate a queue by calling MBeanServer.createMBean a "org.jboss.mq.server.jmx.Queue" object and appropriate ObjectName. Then set the "DestinationManager" on it, and call "start" on it. This can be done remotely as well.

It is clearly stated in the JMS spec, that queue/topic and connection factory
construction is not defined and therefore there is no portable mechanism.

Please do some research in future before wasting people's time with frivolous
questions.

Hi,

I am newbie on JBossMQ, sorry if my questions seem trivial.

First I am looking for MDB code samples who creates dynamically a new topic and place a text message inside. After that, do you know how many topics can a medium size JBoss AS supports? Finally what method a consummer should invoke in order to definitly empty a topic?

Thanks for all answers.
