How to Enable Slf4j Logging in Glassfish

This blog entry will try to setup slf4j as the main logger for glassfish 3.1.1

What you need:
1.) Glassfish 3.1.1 (zipped)

2.) Download the ff jars:
  a.) slf4j-api.jar
  b.) jul-to-slf4j.jar
  c.) logback-classic.jar
  d.) logback-core.jar

Steps
1.) Extract glassfish in the directory of your choice

2.) Copy the jars mentioned above in {glassfish_home}/glassfish/lib/endorsed.

3.) Modify domain.xml in {glassfish_home}/glassfish/domains/domain1/config/domain.xml. We assume that you did not create another domain for this exercise.

4.) In the "java-config" section add the ff "jvm-options":

<jvm-options>-Dlog4j.configuration=file:///${com.sun.aas.instanceRoot}/config/_logging.properties</jvm-options>
<jvm-options>-Dlogback.configurationFile=file:///${com.sun.aas.instanceRoot}/config/logback.xml</jvm-options>

The above 2 statements will configure logger and forward the logging statement to logback.
