The superclass of the generated factory and the interface required for the built classes is provided in the jcommons-factorygen-0.4-lib.jar. This jar file is provided under the GNU LGPL, so that the generated factories can be used in non-GPL code or proprietary code. In order to build factories, you will need the jcommons-factorygen-0.4-builder.jar.
