Put logback.xml into the root of your src directory (not in a subdir). This
worked fine for me (see attached Netbeans project).

The output you were seeing was from the
BasicConfigurator<http://logback.qos.ch/apidocs/ch/qos/logback/classic/BasicConfigurator.html>
(loaded
by default when logback.xml is not found in your classpath), which uses the
ConsoleAppender. It just so happens that your logback.xml also uses the
same type of appender, which might have confused you into thinking that
Logback was ignoring the specified pattern in your configuration.

Hello,

I'm running Netbeans 7.0.1 on a Mac Book Pro with OS Lion.  I'm currently using log4j without any problems.  I wanted to try out logback.

Yesterday I downloaded logback and placed the 4 jar files in the proper location.  I'm able to run the basic logback HelloWorld example.  Here's the code for the HelloWorld example I'm working with:

package helloworld;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class HelloWorld {

  public static void main(String[] args) {

    Logger logger = LoggerFactory.getLogger("helloworld");
    logger.debug("Hello world.");

  }

}

Here's my customized logback.xml file:

<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%date %n [%thread] %level %logger{35} - %n %msg</pattern>
</encoder>
</appender>
<root level="DEBUG">
<appender-ref ref="STDOUT" />
</root>
</configuration>

The problem is...Netbeans (or java) never picks up on my customized logback.xml file.  I'm starting out easy by just changing the pattern to see if I can get it to work.  When I run the project, I see the following on the console:

11:56:33.569 [main] DEBUG helloworld - Hello world.

That's not the pattern I specified in logback.xml.

I'm assuming I just don't have it in the proper location.  I have a copy of logback.xml in the following locations just to see if I had it in the wrong place:

NetBeansProjects -> HelloWorld -> src -> logback.xml

NetBeansProjects -> HelloWorld -> logback.xml

NetBeansProjects -> HelloWorld -> nbproject -> private -> logback.xml

NetBeansProjects -> HelloWorld -> build -> classes -> logback.xml

System -> Libraries -> Java -> Extensions -> logback.xml


I am still unable to get the pattern I'm looking for.

Does anyone know why this would be happening?

Thanks,
Roger
