[jboss-user] [JCA] - Re: Specifying a different WorkManager for a custom resource

[bortx]

I have developed a work around on this issue and I want your opinion about it. It consist on the following.

1.- Deploy a service called custom-work-manager-service.xml defining a custom WorkManager with a custom thread pool with the following content

<server>
  | 
  |  <mbean code="org.jboss.util.threadpool.BasicThreadPool"
  |          name="custom.jca:service=CustomWorkManagerThreadPool">
  |      <!-- The name that appears in thread names -->
  |      <attribute name="Name">CustomWorkManager</attribute>
  |      <!-- The maximum amount of work in the queue -->
  |      <attribute name="MaximumQueueSize">10</attribute>
  |      <!-- The maximum number of active threads -->
  |      <attribute name="MinimumPoolSize">1</attribute>
  |      <!-- The maximum number of active threads -->
  |      <attribute name="MaximumPoolSize">10</attribute>
  |      <!-- How long to keep threads alive after their last work (default one minute) -->
  |      <attribute name="KeepAliveTime">60000</attribute>
  |      <!-- The behaviour when the queue is full -> the calling thread blocks until the queue has room -->
  |      <attribute name="BlockingMode">wait</attribute>     
  |   </mbean>
  | 
  |   <mbean code="org.jboss.resource.work.JBossWorkManager"
  |          name="custom.jca:service=CustomWorkManager">
  |      <depends optional-attribute-name="ThreadPoolName">custom.jca:service=CustomWorkManagerThreadPool</depends>
  |      <depends optional-attribute-name="XATerminatorName">jboss:service=TransactionManager</depends>
  |   </mbean>
  | 
  | </server>


2.- Accesing this work manager from my resource adapter and using it to submit works instead of the one that is provided by jboss in the BootstrapContext:

      WorkManager customWorkManager = null;
  |       try {
  |          MBeanServer server = MBeanServerLocator.locateJBoss();
  |          customWorkManager = (WorkManager) server.getAttribute(new ObjectName(
  |                "custom.jca:service=CustomWorkManager"), "Instance");
  |       } catch (MalformedObjectNameException e) {
  |          // TODO
  |       } catch (Exception e) {
  |          // TODO
  |       }

What do you think about it?
