It's fine.
The first thing I noticed was that you did not set
the Logger. The ActiveMonitor extends
AbstractLoggable.
The DataSourceComponentTest shows how to obtain a
Logger instance for a Component. I would have to
see my code up close again, but the Logger is used
in Configuration.
BTW, the javadocs describe how the configuration
should look--although I believe I have reasonable
defaults for a production system. In order to
override
the frequency to be less than a minute, you will have
to do something like this:
Configuration frequency = new
DefaultConfiguration("frequency", "test");
frequency.setValue("1"); // every millisecond
Configuration root = new
DefaultConfiguration("monitor", "test");
root.addChild(frequency);
testMonitor.configure( root );
(At least until we have an abstract test that loads
a configuration)
Be sure to wait long enough for the Monitor to
actually
look at the resource.
Also, since the code is completely untested the
implementation is theoretical. I may have screwed up
royally ;P
Anyway, if that doesn't work, I will have another look
at it tomorrow.
