Hello Drools Users,
I've been looking into why Drools 5 is logging debug and info messages to
System.out in my app and trying to figure out how to make it stop. It
looks like the SystemEventListener that the SystemEventListenerFactory
returns is a DelegatingSystemEventListener that delegates to a
PrintStreamSystemEventListener. This, by default, uses System.out as the
print stream target. I looked into the Factory and it looks like I can
provide a different SystemEventListener or SystemEventListenerProvider,
but it also mentions that it did not find anything in the properties, so
it fails over to the default SystemEventListenerProvider. Is there a way
to configure a custom SystemEventListener or SystemEventListenerProvider
so that you don't have to call
SystemEventListenerFactory.setSystemEventListenerProvider() at startup?
Thanks,
Steve Ronderos

What you need to do is implement your own SystemEventListener
implementation to override the default one. Before you do anything
meaningful with Drools, you'll want to override the default by calling:
SystemEventListenerFactory.setSystemEventListener(<YOUR
SystemEventListenerImpl>);
Here's a basic no-op listener:
new SystemEventListener () {
public void debug(String arg0) { }
public void debug(String arg0, Object arg1) {}
public void exception(Throwable arg0) {}
public void exception(String arg0, Throwable arg1) {}
public void info(String arg0) {}
public void info(String arg0, Object arg1) {}
public void warning(String arg0) {}
public void warning(String arg0, Object arg1) {}
};
In reality what you probably want to do is hook in your application's
logger here so it will respect the same log levels the rest of your
application runs under.

Thanks Macon,
That is the information I was looking for. I was looking at the code and
it looked like there were some comments hinting at making the
SystemEventListener configurable. Is this a future feature? or am I
reading too much into the comments?
Thanks,
Steve Ronderos

Please respond to Rules Users List
What you need to do is implement your own SystemEventListener
implementation to override the default one. Before you do anything
meaningful with Drools, you’ll want to override the default by calling:
SystemEventListenerFactory.setSystemEventListener(<YOUR
SystemEventListenerImpl>);
Here’s a basic no-op listener:
new SystemEventListener () {
public void debug(String arg0) { }
public void debug(String arg0, Object arg1) {}
public void exception(Throwable arg0) {}
public void exception(String arg0, Throwable arg1) {}
public void info(String arg0) {}
public void info(String arg0, Object arg1) {}
public void warning(String arg0) {}
public void warning(String arg0, Object arg1) {}
};
