Just for my own understanding of Jboss JMS/MDB implementation, what is the
difference between changing the invoker configuration as described below and
changing the container pool configuration in the Standard Message Driven
Bean (standardjboss.xml):
<container-pool-conf>
<MaximumSize>100</MaximumSize>
</container-pool-conf>
If I put the Maximum size of the container-pool-conf to 1, I will also
serialize all message handling, am I not?
If yes, what make more sense between this change and the invoker change
(also I agree that trying to serialize the message handling is not a good
idea)?

The number of concurrent sessions for an MDB is configured on the invoker.
This is from standardjboss.xml in 3.2. You can make your own configurations
using jboss.xml
This isn't guaranteed to work. The MDB could rollback the message delivery
causing the messages to be delivered out of order.
Why do people take an asynchronous system like messaging and try to
reimplement a synchronous system. What is wrong with invocations?
