Just a reminder to people to re-read this email "api's, factories

<br>
So we can start to standardise how our factories and services work,
so we get the best of our container interoprability - like spring,
osgi etc.<br>

Hi all,<br>
<br>
following the suggestions of Mark on how to create a new
Service I just pushed a new one named ExecutorProvider. The
idea here is that we should never manually create and start
Threads in the Drools code because this is inefficient and
event worse is not portable in many enterprise environments.
In this way it will be possible to provide different
implementations of this Service that could work with J2EE,
Spring or other similar managed environments.<br>
<br>
The ExecutorProvider is defined as it follows:<br>
<br>
public interface ExecutorProvider extends Service {<br>
Executor getExecutor();<br>
<T> CompletionService<T>
getCompletionService();<br>
}<br>
<br>
I am already using it to make the jitting compilation of my
MvelConstraint an asynchronous process and also to replace
the Threads used in the KnowledgeAgentImpl and
ResourceChangeScannerImpl. For instance in the
KnowledgeAgentImpl I replaced this code:<br>
<br>
this.thread = new Thread( this.changeSetNotificationDetector
);<br>
this.thread.start();<br>
<br>
with this one:<br>
<br>
this.notificationDetectorExecutor =<br>
ExecutorProviderFactory.getExecutorProvider().<Boolean>getCompletionService()<br>
.submit(this.changeSetNotificationDetector, true);<br>
<br>
where the notificationDetectorExecutor is a Future so I can
stop its execution with:<br>
<br>
this.notificationDetectorExecutor.cancel(true);<br>
<br>
instead of doing:<br>
<br>
this.thread.interrupt();<br>
<br>
Also note that, at the moment, the ExecutorService
internally used in the ExecutorProviderImpl (the only
ExecutorProvider implementation currently available) always
uses daemon Threads, so the JVM won't be prevented to
terminate if there are some of them still running.<span
