Comments for Handful of sand http://php.sabscape.com/blog What we know is but a handful of sand when compared to the world of unknown Fri, 23 Mar 2012 21:38:53 +0000 hourly 1 http://wordpress.org/?v=3.1.2 Comment on Scaling with the Spring JMS MessageListenerContainer by claudio santana http://php.sabscape.com/blog/?p=315&cpage=1#comment-369 claudio santana Fri, 23 Mar 2012 21:38:53 +0000 http://php.sabscape.com/blog/?p=315#comment-369 Thanks for posting this example. It was very useful to see a full implementation of this sort of funcionality in one place rather than most documentation which doesn't put together usages examples. I just have to say your configuration file is incorrect. The attribute concurrency belongs to the listener-container element not to listener. You can verify this by http://www.springframework.org/schema/jms/spring-jms-{2.5|3.0|3.1}.xsd It would be nice if you update your post so people can take full advantage of your blog/tutorial.

I just want to inform you about my observation. The default rejection policy of this thread pool executor is Abort as per java documentation. http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/ThreadPoolExecutor.html But in your article it is mentioned that the default policy is Caller Runs. I just want to inform to enhance the correctness of the article. I hope you will not take it otherwise. Hi Sabarish,

Your article “Spring Integration – Channel mysteries” is very well explained and informative.

I just want to inform you about my observation.

The default rejection policy of this thread pool executor is Abort as per java documentation.

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/ThreadPoolExecutor.html

But in your article it is mentioned that the default policy is Caller Runs.

I just want to inform to enhance the correctness of the article. I hope you will not take it otherwise.

So how dynamic is this 'restriction' imposed by the 3rd party? I mean, does it change every minute or is it like defined once and changed quite rarely? If it doesn't change often, you could just change the concurrency attribute of the Spring MLC when you 'hear' about the change in the restriction from the 3rd party. The other option is to introduce a bounded queue between your JMS consumer and the code that interfaces with your 3rd party. Have a threadpool of workers pick up tasks from the queue, the worker being the code that interfaces with your 3rd party. This threadpool's pool size can be adjusted dynamically to reflect the 'restriction' value of the 3rd party. Hope this helps @Vijay
