ctory can be used with Java SE ExecutorService implementations directly.<p>

 Example:
 <pre>
 &#47;**
 * Create a ThreadPoolExecutor using a ManagedThreadFactory.
 * Resource Mappings:
 *  type:      jakarta.enterprise.concurrent.ManagedThreadFactory
 *  jndi-name: concurrent/tf/DefaultThreadFactory
 *&#47;

 &#64;Resource(name="concurrent/tf/DefaultThreadFactory")
 ManagedThreadFactory tf;

 public ExecutorService getManagedThreadPool() {

   // All threads will run as part of this application component.
