Log4J : Path to properties file

For Glassfish, we normally put the log4j.properties in the "domain / config" directory.

To enable Glassfish to find it, add the following to the Glassfish JVM settings. Easiest way is to use the Admin console i.e. Application Server / JVM Settings / JVM Options.

Add this line:

-Dlog4j.configuration=file:///${com.sun.aas.instanceRoot}/config/log4j.properties

Enjoy!

Java : Axis2 client and Log4J

I was busy testing a client developed using the Eclipse plug-ins in the previous post.

This came up with the following error message.

log4j:WARN No appenders could be found for logger (org.apache.axis2.description.AxisService).
log4j:WARN Please initialize the log4j system properly.

To set this up inside an Eclipse project:

* Create a new folder in the project called e.g. "log4j".
* Add a file to that folder called log4j.properties which contains something like:

# Set root category priority to INFO and set its only appender to A1
log4j.rootCategory=INFO, A1

# A1 is set to be a ConsoleAppender (writes to system console).
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

* In the project's "Run Dialog", click on the "Classpath" tab / "Advanced" / "Add folder" and then browse to the "log4j" folder previously created.
* That's it

Enjoy!
