How to use CVAL license
Hello,
I used Vaadin Calendar add-on and i purchase CVAL license key, but I can not find way, how to integrate this key into application.
Can someone help me with integration of this kind of license key?
Hi Michal,
CVAL is granted and used by Developers during development phase and it's not required to integrate the license key string into applications developed (= project result).
License is required when developing project(s) that uses Vaadin Calendar Add-on software.
Once the Project is completed the licensee may license, for free or against a payment, Project Result including Licensed Software whether regarded as derivative works or not. End users using Project Result that does not involve changing any source code are not required to have a valid License.
For detailed information you can read through section 2. Grant of License from CVAL 2.0
I hope this answers your question.
