3. Fire up GlassFish and open the admin web UI inside a browser (for example http://localhost:4848).

5. Now Add new property

'-Dlog4j.configuration=file:///${com.sun.aas.instanceRoot}/lib/log4j.properties' based on as you have copied log4j.properties under lib folder in above Step 2. (basically specify the path of log4j.properties file)

6. Click on the Save button and restart glassfish.
