• Using the Apache commons logger is the recommended way to do logging in Sakai tools

1. 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:

      Code Block
      xml xml
      <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
2. Adding the logger to your code
   1. Add the following line just below your class line:

      Code Block
      private static Log log = LogFactory.getLog(TaskListManagerDaoImplMyClass.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):

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