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

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;
```
