    <p>You could use an <a href="http://java.sun.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html" rel="nofollow noreferrer">ExecutorService</a> (containing multiple threads) to process your individual items of work by calling submit(). The submit method returns a Future, which will encapsulate either the result of the processing or <strong>any exception thrown</strong>. In other words, the threads within your <code>ExecutorService</code> will not terminate if an exception occurs.</p> <p><strong>Example</strong></p> <p>First create an executor service containing more than one thread:</p> <pre><code>ExecutorService execService = Executors.newFixedThreadPool(5); </code></pre> <p>Define the item of work we wish to submit as a <code>Callable</code>:</p> <pre><code>public class MyWorkItem implements Callable&lt;Integer&gt; { public Integer call() throws Exception { int result = new Random().nextInt(5); // Randomly fail. if (result == 0) { throw new IllegalArgumentException("Fail!"); } return result; } } </code></pre> <p>Submit some work for the executor service to do, and store the <code>Future&lt;Integer&gt;</code> for each <code>Callable&lt;Integer&gt;</code>.</p> <pre><code>List&lt;Future&lt;Integer&gt;&gt; futures = new LinkedList&lt;Future&lt;Integer&gt;&gt;(); for (int i=0; i&lt;10; ++i) { futures.add(execService.submit(new MyWorkItem())); } </code></pre> <p>Now iterate over the futures attempting to retrieve the result of each work item (we could use a <code>CompletionService</code> for this).</p> <pre><code>for (Future&lt;Integer&gt; future : futures) { try { Integer result = future.get(); } catch(Exception ex) { // Handle exception. } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
