    javax.resource.ResourceExcption while using JmsXA

    Prabhudatt Rana Newbie

      We are running our application with JBoss 4.2.3 GA with JBM 1.4.0SP3.
      I have just changed my anti pattern ,connection creation code to JmsXA lookup. I could see a great performance improvment.

      With default setting i am getting below error. I guess it has something do with default max pool size, which is 20. in hajndi-jms-ds.xml
      i.e. <max-pool-size>20</max-pool-size>

       Could not create a session: javax.resource.ResourceException: No ManagedConnections available withi
      n configured blocking timeout ( 30000 [ms] )
      javax.jms.JMSException: Could not create a session: javax.resource.ResourceException: No ManagedConn
      ections available within configured blocking timeout ( 30000 [ms] )

      I have increased it max-pool-size and i could reduce frequency of above error. Our application does a heavy usage of messaging.
      I have two basic question
      1) Above error is because of low pool size ?
      if Yes , what is the max. limit for max.pool.size
      2) If above error is not because of pool size , what could be other reason ?

      Any pointer to this ?
