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.

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
