This section describes some interesting aspects of how the ServiceMix JBI container interacts with the File Binding application. The Java class files are located in the servicemix-1.0.jar file in the ServiceMix installation directory. To look at the Java source code, unjar and decompile the .class files or download the source code. Viewing the Java source code is necessary for understanding the information in this section below.

...

1. The ServiceMix container reads the servicemix.xml file and sees it needs to instantiate a FilePoller.
2. The container calls the init() method of FilePoller as well as the init() methods of its parents
3. The container determines that FilePoller is an MBean and, therefore, calls the " start" () method of FilePoller, which it inherits from its parent PollingComponentSupport.
4. The start() method will:
   a. Create a timerTask, which overrides the " run() " method inline, the run() method will eventually get the WorkManager and schedule work.
   b. Start The start() method uses the "timer" (created in the init() method) to schedule the timerTask it just created at a fixed rate, timer.scheduleAtFixedRate(timerTask, firstTime, period). Recall "period" is a property FilePoller. It was assigned the value of 1000ms by dependency injection from the servicemix.xml file.
   c. Timer timer will call the run() method of the timerTask periodically.
   d. timerTask's run method() is defined inline.
   e. it will get the workManager object (see below for details)
   f. the work manager will call scheduleWork(PollingComponentSupport.this). note: it passes in PollingComponent support, which by virtual of its inheritance hierarchy, is also of type "Work", which is also a "runnable"
   g. WorkManager.scheduleWork(Work) will likely create or get a Thread, passing in a runnable, i.e. PollingComponentSupport, and call its "run" method
   h. PollingComponent's run method calls poll(), which is implemented in filePoller
   i. From this point on the call sequence can be followed in filePoller
   6. The start method of PollingComponentSupport, will eventually call super.start(), which propagates up to call the start method of BaseLifeCycle, which sets the component state to RUNNING
