Re: Support for log4j?

[Aaron Crow]

Hi Evgeny,

I think you may be asking the wrong question, or I'm misunderstanding what 
you're asking for. I use a very vanilla log4j configuration, and there is 
good documentation all over the web. First, the official log4j documentation 
is well above-average:

http://logging.apache.org/log4j/1.2/manual.html

And also, for example:

http://www.devdaily.com/blog/post/java/simple-log4j-example/
http://www.mobilefish.com/developer/log4j/log4j_quickguide_examples.html

Please let me know if you had a more specific question, and my apologies if 
I misunderstood your question...

Best wishes,
Aaron

Hi Evgeny,

Sure, I will. First though, I'd like to say that I don't consider it the 
ideal solution. In my case I just want the Restlet's access logs, and if 
I can emulate those myself with my own logging statements, I'll be 
happier. That being said, here's what I did to redirect Restlet's JDK 
logging to slf4j and then log4j:

1) Read http://www.slf4j.org/legacy.html

2) Added the following to my pom (**verbosity warning!**):

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.4.3</version>
        <exclusions>
          <!-- needed to avoid endless recursion, per:
               http://www.slf4j.org/legacy.html
          -->
          <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-jdk14</artifactId>
          </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.5.2</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jul-to-slf4j</artifactId>
        <version>1.5.2</version>
    </dependency>
    <dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>1.2.12</version>
    </dependency>

3) Added the following to my app's main method:
  // needs: import org.slf4j.bridge.SLF4JBridgeHandler;
  SLF4JBridgeHandler.install();

I then did what you normally do to configure log4j, and saw restlet's 
logging go to the targets I configured in my log4j.properties file. I do 
see the formatting is a little awkward, but at least it's down to one 
line. (I never made my peace w/jul's forced multi-line logging ;-)


Hope this helps!
Aaron
