I'm looking for a definitive answer on configuring the pool size for an MDB.  I've seen several conflicting answers between forum posts and documentation, see http://community.jboss.org/thread/147300?tstart=30
 
Is it the @Pool annotation?  http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/reference/1.0.7/html/SessionBean_and_MDB_configuration.html
 
{code}@Pool(value=PoolDefaults.POOL_IMPLEMENTATION_STRICTMAX,maxSize=50,timeout=1800000){code}
 
Is it the @PoolClass annotation?   http://www.jboss.org/ejb3/docs/reference/build/reference/en/html/session-bean-config.html
 
{code}@PoolClass (value=org.jboss.ejb3.StrictMaxPool.class, maxSize=50, timeout=1800000){code}
 
Is it the MaxPoolSize ActivationConfigProperty?
 
{code}
@MessageDriven(
    activationConfig={
        ...
        @ActivationConfigProperty(propertyName="MaxPoolSize",propertyValue="50")
    }
)
{code}
 
I've also seen a suggestion to change this section in ejb3-interceptors-aop.xml
 
{code:xml}
     <annotation expr="!class(@org.jboss.ejb3.annotation.Pool)">
         @org.jboss.ejb3.annotation.Pool (value="StrictMaxPool", maxSize=15, timeout=10000)
      </annotation>
{code}
 
But that applies to every MDB.
 
I've also looked at the message-driven-bean invoker-proxy-binding in standardjboss.xml and changing the MaximumSize, but that also applies to every MDB.
 
I've tried the @Pool annotation.  I see that MaxPoolSize is 50 in the jmx-console, but if I do a thread dump when there are many thousands of messages backed up in the queue, I only see 15 WorkManager threads processing messages.
 
So what do I need to do to get more than 15 messages processed at once?
 
I'm using JBoss 5.0.1.GA and JBoss Messaging 1.4
