logging with Java logging API in j2ee???

[georgehategan]

Hello everyone... I have a little problem about including logging.properties file for java logging API in j2ee application running with jboss. What other settings do I have to do in order to make it work. I have worked with logging API for simple java applications and used the -Djava.util.logging.config.file=myfile argument that was working fine but there has to be something else with j2ee applications. Please give me some ideas. 10x a lot. G

What problem/error exactly have you got ? Which JBoss version ?

Have you tried using :

System.setProperty("java.util.logging.config.file", "myfile");

JBoss uses log4j to do all its logging, so you might consider using that.

Actually I got no error because I didn't know how to include that file (System.setProperty...)
I know that Jboss uses log4j but still want to use java logging api. Another question... Where do I have to use System.setProperty? I suppose not in every file that instantiates a Logger, but somewhere where it runs just once. I thought it might be included as xml element or something like this. Thanks for your help and I am waiting for your answer. All the best, G.

In your application I would have a simple class like this :

public class InitializeLogger {
  public InitializeLogger(String file) {
    System.setProperty("java.util.logging.config.file", file);

  }
}

And then in your application, create a static intstance of the class, so that it is only ever loaded once :

static InitializeLogger il = new InitializeLogger();

Or rather :

static InitializeLogger il = new InitializeLogger("myfile");

It looks ok to me. Last question... I hope... Where do I store my .properties file inside the war|ear|jar? and what relative path should I use? Regards, G

You can store it wherever your like - it depends on the type of application & how you intend to use it - I have no idea if java.util.logging classes can read a file from within a jar file, so I guess you will have to do a bit of trial and error ...
