Using the commons logger

Adding the commons-logger dependency to your project.xml

1. Add the following to the dependencies block of your project.xml file to include the commons-logger:

   <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.0.4</version> </dependency>

   • The commons logger is included in shared/lib by Sakai itself so you do not need to package it in your tool war file (hence there is no <war.bundle>true</war.bundle>)

   • Version 1.0.4 was the current version when this was written

Adding the logger to your code

1. Add the following line just below your class line:

   private static Log log = LogFactory.getLog(MyClass.class);

   • Make sure your class name is listed in place of MyClass

2. The commons logger requires 2 imports (eclipse will insert these for you):

   import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory;
