    <p>Lest's consider that I have the following:</p> <pre><code>public class MyRunnable implements Runnable { public void run() { //do something expensive } } public class ThreadExecutor { private TaskExecutor taskExecutor; public ThreadExecutor(TaskExecutor taskExecutor) { this.taskExecutor = taskExecutor; } public void fireThread(){ taskExecutor.execute(new MyRunnable()); } } </code></pre> <p>my xml is the following:</p> <pre><code>&lt;bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor"&gt; &lt;property name="corePoolSize" value="5" /&gt; &lt;property name="maxPoolSize" value="10" /&gt; &lt;property name="queueCapacity" value="25" /&gt; &lt;/bean&gt; &lt;bean id="threadExecutor" class="com.vanilla.threads.controllers.ThreadExecutor"&gt; &lt;constructor-arg ref="taskExecutor" /&gt; &lt;/bean&gt; </code></pre> <p>in my Spring MVC controller I start the task:</p> <pre><code>@RequestMapping(value="/startTask.html", method=RequestMethod.GET) public ModelAndView indexView(){ ModelAndView mv = new ModelAndView("index"); threadExecutor.fireThread(); return mv; } </code></pre> <p>Now let's consider that I would like to create another request(<code>@RequestMapping(value="/checkStatus.html"</code>) which will tell if the the task started in my previous Request has been finished.</p> <p>So my questions are simple:</p> <p>1) Can I assign name to the task in TaskExecutor and if yes, how can I do it?</p> <p>2) How can I check that the task with that specific name has been done?</p>

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.
