Inbound MDP - multiple connection threads in a pool

Hi,

I read a blog about configuring a pool of connections (inbound): http://gnodet.blogspot.com/2006/12/over-past-weeks-i-spend-some-times-load.html

I am using Spring+Jencks(2.1)+ActiveMQ(4.1.1).
I would like to use JcaPooledConnectionFactory (with jencks JCA inbound support).

I configured the org.jencks.amqpool.JcaPooledConnectionFactory , but it doesn't seem to work, there is only one connection and multiple sessions.

Here is my configuration:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
 
  <bean id="broker" class="org.apache.activemq.xbean.BrokerFactoryBean">
    <property name="config" value="classpath:broker.xml" />
  </bean>
 
  <bean id="transactionManager" class="org.jencks.factory.TransactionManagerFactoryBean"/>
 
  <bean id="resourceAdapter" class="org.apache.activemq.ra.ActiveMQResourceAdapter" depends-on="broker">
      <property name="serverUrl" value="vm://localhost"/>          
  </bean>
   
  <bean id="AMQconnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory"/>
   
  <bean id="connectionFactory" class="org.jencks.amqpool.JcaPooledConnectionFactory">
    <constructor-arg value="vm://localhost" />
    <property name="connectionFactory" ref="AMQconnectionFactory" />
    <property name="maxConnections" value="8" />
    <property name="maximumActive" value="8" />
    <property name="transactionManager" ref="transactionManager"/>
    <property name="name" value="LocalBroker"/>
  </bean>
       
  <bean id="jencks" class="org.jencks.JCAContainer">  
    <property name="transactionManager" ref="transactionManager"/>
    <property name="threadPoolSize" value="25"/>
    <property name="resourceAdapter" ref="resourceAdapter"/>    
  </bean>

  <bean id="activspec" class="org.apache.activemq.ra.ActiveMQActivationSpec">
        <property name="destination" value="Hello.Queue"/>
        <property name="destinationType" value="javax.jms.Queue"/>
        <property name="enableBatch" value="true" />
        <property name="maxMessagesPerBatch" value="1" />
        <property name="maxSessions" value="25" />
  </bean>

  <bean id="inboundConnector" class="org.jencks.JCAConnector">
    <property name="jcaContainer" ref="jencks" />    
    <property name="activationSpec" ref="activspec"/>
    <property name="ref" value="echoBean"/>
  </bean>

  <bean id="echoBean" class="mdpojo.approach.activemq.HelloBean" singleton="true"/>
</beans>


I read a post: http://www.nabble.com/How-to-configure-multiple-connection-threads-tt15447114.html#a15447114
Does it actually work? I am not able to check it - logs are all the time the same...

So the only way to do it is to copy/paste the inboundConnector???  It doesn't seem to be a good practice... What if I would like to have 20 inbound-connection pool?
