java.lang.NoClassDefFoundError: org/apache/struts/legacy/GenericDataSource

There is a jar file called struts-legacy.jar that contains the GenericDataSource and GenericConnection classes. Not sure how long this jar has been included in the distribution, but I just downloaded the 1.1 release and it's there. You need to get this jar and put it in the WEB-INF/lib directory.
