[jboss-user] [JCA/JBoss] - Re: WorkManager thread pooling

How/Where did you configure the ThreadPool ?

The JBossWorkManager is configured in $JBOSS_HOME/server/default/deploy/jbossjca-service.xml 
  | <mbean code="org.jboss.util.threadpool.BasicThreadPool"
  |          name="jboss.jca:service=WorkManagerThreadPool">
  |      <!-- The name that appears in thread names -->
  |      <attribute name="Name">WorkManager</attribute>
  |      <!-- The maximum amount of work in the queue -->
  |      <attribute name="MaximumQueueSize">1024</attribute>
  |      <!-- The maximum number of active threads -->
  |      <attribute name="MaximumPoolSize">100</attribute>
  |      <!-- How long to keep threads alive after their last work (default one minute) -->
  |      <attribute name="KeepAliveTime">60000</attribute>
  |   </mbean>
  | 
  |   <mbean code="org.jboss.resource.work.JBossWorkManager"
  |          name="jboss.jca:service=WorkManager">
  |      <depends optional-attribute-name="ThreadPoolName">jboss.jca:service=WorkManagerThreadPool</depends>
  |      <depends optional-attribute-name="XATerminatorName">jboss:service=TransactionManager</depends>
  |   </mbean>
You should be able to plugin custom threadpool implementation here . 
But before doing so make sure that your observation regarding the BasicThreadPool is correct .
