如何配置消息驱动Bean的池大小

Question

I would like to configure the pool size of a MDB but just one. I deploy my application on JBOSS 6 or Glassfish 3 so the solution must be standard.

I found for JBOSS maxSession for @ActivationConfigProperty but it is not standard For glassfish i don't find anything to create sun-ejb-jar.xml ...

Can you help me ? thanks.

Answer 1

For glassfish, you can specify bean's max-pool-size to 1 in glassfish-ejb-jar.xml. See deployment guide .

Answer 2

You'll need a sun-ejb-jar.xm which goes in the META-INF folder.

Here's one that you can use / edit.

<sun-ejb-jar>
    <enterprise-beans>
        <unique-id>0</unique-id>
        <ejb>
            <ejb-name>YOUR EJB NANME</ejb-name>
            <jndi-name>YOUR JNDI NAME</jndi-name>
            <bean-pool>
                <steady-pool-size>1</steady-pool-size>
                <resize-quantity>1</resize-quantity>
                <max-pool-size>3</max-pool-size>
                <pool-idle-timeout-in-seconds>600</pool-idle-timeout-in-seconds>
            </bean-pool>
        </ejb>
    </enterprise-beans>
</sun-ejb-jar>

Answer 3

This is not settable through standard Java EE 6 activation config properties, which are:

• acknowledgeMode ,
• messageSelector ,
• subscriptionDurability ,
• destinationType .

All others are provider-specific.
