Application development is complitely free. Furthermore, you can deploy the developed application for testing and validation at the development time.
A commercial license must be obtained for production use of the applications that use IT Mill Toolkit libraries.
A deployment license is required for each deployed copy of a program that uses Toolkit library. To be more exact, each Java Virtual Machine (JVM) that runs a program that uses IT Mill Toolkit libraries, must have an unique deployment license. For example, if the program is deployed to multiple servers (for load balancing or other reasons), each server needs an unique license.
If the number of server installations is so high that separate deployment licenses are not an option, please contact sales to hear about OEM licensing options.
Deployment licenses can be purchased online from IT Mill Ltd.
If you are interested in OEM-license for your product, please contact sales at IT Mill Ltd.
The actual legal license text is in license.pdf.
Technically license is stored as itmill-toolkit-license.xml -file, that is usually store in WEB-INF -directory of the web-application. The license file contains information about the scope and limitations of the license in fairly readable form, so you might want to check the file contents. Toolkit package is shipped with unlimited license for development and testing purposes.
Free unlimited development license license-file is included in product package in lib -directory
The previous version 3 of the product was called Millstone User Interface Library. Millstone library was licensed with very liberal LGPL-license. The latest free release of Millstone User Interface Library (version 3.1) can still be found from sourceforge.
The new version 4 of the library, now called IT Mill Toolkit, is not licensed with an open source license. This does not mean that the sources are closed, source code is included in the product package for your convenience.
Why did we change the license? Putting a clear transparent pricing model on the product makes our customers decision-making easier. They know how much they are paying for and that they can expect commercial grade quality product for their money.
