Apache Cactus on OS X

Apache Cactus is a test framework for Java server-side code.

If you try to use the ant cactus task on a stock OS X, you’ll run into the dreaded

“taskdef A class needed by class org.apache.cactus.integration.ant.CactusTask cannot be found: junit/framework/Test”

even though you have the junit jar in your classpath.

Solution:

1. find out which ant you use: $ ls -al `which ant`

2. copy junit-x.y.z.jar into that ../lib location, for example, /Developer/Java/Ant/lib
