Hi,
we need a single mdb instance which is never destroyed but listens as long as the server is running. Instance thereby means one class instance.
We tried this by deploying the MDB with:
<bean-pool>
<steady-pool-size>1</steady-pool-size>
<resize-quantity>0</resize-quantity>
<max-pool-size>1</max-pool-size>
<pool-idle-timeout-in-seconds>0</pool-idle-timeout-in-seconds>
</bean-pool>
But this doesn't has the required result.
The server creates one mdb instance but as soon as a message arrives in the queue a new mdb is created and destroyed after the message is processed:
TotalBeansDestroyed 1 count -- Number of beans destroyed from the associated pool
NumBeansInPool 1 High Water Mark: 1 count
Low Water Mark: 0 count
TotalBeansCreated 2 count -- Number of beans created in the associated pool
I thought pool-idle-timeout-in-seconds = 0 would force the server to never remove a idle bean and max-pool-size = would ensure there is only one bean in the pool.
So why does the container creates a new instance when a message arrives and how can we prevent it. We use version GlassFish v3 (build 74.2).
Thanks for any idea
Petra
