Limiting the MDB pool size to 1

[shadowfury]

Is it possible to limit the size of the MDB pool to 1 so that there is only one bean consuming messages off the queue? If so, how would this be configured?

+1. I am also interesting in this type of configuration. I want to be able to limit the number of consumer threads for a given queue for resource management purposes.

This is not JBoss Messaging config, it is MDB container config. The MDB container is agnostic as to the jms provider, whether it is JBoss Messaing, JBossMQ or some other provider.

See
http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigJBossMDB

Look at the maximumSize parameter.

Great! Thanks for the quick response.

Just for those following this thread, if you want to tune the MDB container pooling options in EJB3, read up on @org.jboss.annotation.ejb.PoolClass in the documentation.

Can you provide a more specific reference please?

http://docs.jboss.org/ejb3/embedded/api/org/jboss/annotation/ejb/PoolClass.html is not really helpful.

Much appreciated.

Thank you
