 <pre>public interface <span class="typeNameLabel">ManagedExecutorService</span>
 extends java.util.concurrent.ExecutorService</pre>
 <div class="block">A manageable version of a <code>ExecutorService</code>.
  <p>
  A ManagedExecutorService extends the Java&trade; SE ExecutorService to provide
  methods for submitting tasks for execution in a Jakarta&trade; EE environment.
  Implementations of the ManagedExecutorService are
  provided by a Jakarta EE Product Provider.  Application Component Providers
  use the Java Naming and Directory Interface&trade; (JNDI) to look-up instances of one
  or more ManagedExecutorService objects using resource environment references.
  ManagedExecutorService instances can also be injected into application
  components through the use of the <code>Resource</code> annotation.
  <p>
  The Jakarta Concurrency specification describes several
  behaviors that a ManagedExecutorService can implement.  The Application
  Component Provider and Deployer identify these requirements and map the
  resource environment reference appropriately.
  <p>
  The most common uses for a ManagedExecutorService is to run short-duration asynchronous
  tasks such as for processing of asynchronous methods in Jakarta
  Enterprise Beans or for processing async tasks for Servlets that
  supports asynchronous processing.
  <p>
  Tasks are run in managed threads provided by the Jakarta EE Product Provider
  and are run within the application component context that submitted the task.
  All tasks run without an explicit transaction (they do not enlist in the application
  component's transaction).  If a transaction is required, use a
  <a href="../../../jakarta/transaction/UserTransaction.html" title="interface in jakarta.transaction"><code>UserTransaction</code></a> instance.  A UserTransaction instance is
  available in JNDI using the name: &quot;java:comp/UserTransaction&quot; or by
  requesting an injection of a <a href="../../../jakarta/transaction/UserTransaction.html" title="interface in jakarta.transaction"><code>UserTransaction</code></a> object
  using the <code>Resource</code> annotation.
  <p>
  Example:
  <pre>
  public run() {
    // Begin of task
    InitialContext ctx = new InitialContext();
    UserTransaction ut = (UserTransaction) ctx.lookup("java:comp/UserTransaction");
    ut.begin();

    // Perform transactional business logic

    ut.commit();
  }
  </pre>

  Tasks can optionally provide an <a href="../../../jakarta/enterprise/concurrent/ManagedTaskListener.html" title="interface in jakarta.enterprise.concurrent"><code>ManagedTaskListener</code></a> to receive
  notifications of lifecycle events, through the use of <a href="../../../jakarta/enterprise/concurrent/ManagedTask.html" title="interface in jakarta.enterprise.concurrent"><code>ManagedTask</code></a>
  interface.
  <p>
  Example:
  <pre>
  public class MyRunnable implements Runnable, ManagedTask {
    ...
    public void run() {
      ...
    }

    public ManagedTaskListener getManagedTaskListener() {
      return myManagedTaskListener;
    }
    ...
  }

  MyRunnable task = ...;
  ManagedExecutorService executor = ...;

  executor.submit(task); // lifecycle events will be notified to myManagedTaskListener
  </pre>

  Asynchronous tasks are typically submitted to the ManagedExecutorService using one
  of the <code>submit</code> methods, each of which return a <code>Future</code>
  instance.  The <code>Future</code> represents the result of the task and can also be used to
  check if the task is complete or wait for its completion.
  <p>

  If the task is canceled, the result for the task is a
  <code>CancellationException</code> exception.  If the task is unable
  to run due to a reason other than cancellation, the result is a
  <a href="../../../jakarta/enterprise/concurrent/AbortedException.html" title="class in jakarta.enterprise.concurrent"><code>AbortedException</code></a> exception.
  <p>

 <pre>

   * Resource Mappings:
   *  type:      jakarta.enterprise.concurrent.ManagedExecutorService
   *  jndi-name: concurrent/ThreadPool

  public List&lt;Account&gt; getAccounts(long accountId) {
    try {
        javax.naming.InitialContext ctx = new InitialContext();
        <b>ManagedExecutorService mes = (ManagedExecutorService)

        // Create a set of tasks to perform the account retrieval.
        ArrayList&lt;Callable&lt;Account&gt;&gt; retrieverTasks = new ArrayList&lt;Callable&lt;Account&gt;&gt;();
        retrieverTasks.add(new EISAccountRetriever());
        retrieverTasks.add(new RDBAccountRetriever());

        // Submit the tasks to the thread pool and wait for them
        // to complete (successfully or otherwise).
