Jolene has 2 licences. LGPL for jolene-core and BSD for jolene-plugins.

Jolene is licensed under the LGPL version 2.1. You are free to use Jolene in proprietary commercial or GPL software.

The Jolene struts plugin is licensed under the BSD license. The reason for the BSD license is to allow developers to create alternate plugin implementatations. The struts plugin provided is my preferred implementation but developers should be free to use this code as a basis for alternate implementatations if they so desire.

If you have developed a plugin for one of the myriad of other Java web frameworks. then contact me and I can include it in future distributions or cross link with you.
