Programmatic Log4j Configuration

[barthjj]

Can anyone help me use programmatic log4j configuration in a Seam application? I want to continue to use the @Logger, because that's sweet, but I need configurations to vary between DEV, TEST, PROD.

Looks like nobody cares about this. I'll respond with my results so far anyway.

I've setup a component as:

@Name("configLogger")
@Scope(value = ScopeType.APPLICATION)
@Startup
public class ConfigLog4j {

 @Create
 public void configureLogger() {
 URL url = new URL("file:///log4j.xml");
 PropertyConfigurator.configure(url);
 }
}

I've setup the log4j.xml that is packaged with the war to be priority value="INFO". I made the external log4j.xml set priority value="DEBUG". I'm expecting that after the above code is run, all of the logs should switch to DEBUG, but nothing is changing.

Any help?

Thanks for the link. I looked at the code there and found out what my problem was. I was using PropertyConfigurator instead of DOMConfigurator. Here's the working code

@Name("configLogger")
@Startup
@Scope(APPLICATION)
public class ConfigLog4j{

 @Create
 public void init() {
 DOMConfigurator.configure("c:/log4j.xml");
 }
}
