Dear ZK users,

The change from ZK 3's GPL and commercial model to the LGPL offers the community the ability to use ZK 5 CE wherever they please, including open source or commercial applications.

For people who count on ZK 3 PE and EE, we continue our support for the open source community by providing any GPL-compatible or open source project the ability to make use of ZK 5 PE and EE under ZK Open Source License free of charge. If you are interested in this, please contact [email protected].

For more licensing information, please visit http://www.zkoss.org/license/
and ZK 5 licensing FAQ http://www.zkoss.org/license/faq.dsp.

Best,
Jim Yeh
The ZK Team

Hi, Robert,

ZK community edition is LGPL licensed so it's free for open source and commercial development & deployment.

As for ZK Professional and Enterprise edition, they are freely available for "open source projects" under "ZK Open Source License". If your project is developed under OSI-Approved open source license, we will provide you an "ZK Open Source License" for free use. On the contrary, if you are using ZK Professional/Enterprise in a non-open source software, you need a commercial license from Potix.

In your case, if what you need is charting, there is a "flashchart" component in ZK community edition for free or you can implement your own charting. Here are two articles that might be helpful:

The licence says:
* Freely available for open source projects. Please contact us for written permission.

What's about in-house-development? Software that is written from the own IT-department - developer and customer/user is the same company, there is no resell.
Actually we've progged non-critical projects (most critical stuff runs on mainframe aka AS/400) - with no need of "advanced" versions.

I evaluate an OLAP-like-system with ZK, but there is need for JFreeChart. Unlike the old versions (< 3.6) the enterprise version not under dual (GPL and commercial) anymore?

I gave up on ZK, tried to use the Calendar with version 5 but didn't work. Then realized ZK 5 LGPL is a community version with a set of specific components. Then ZK 5 Enterprise has more components but the license is by request?

The whole thing is vague and risky, at least this experience with ZK made me look at other libs lke Vaadin, OpenFaces and PrimeFraces all high quality web frameworks with clearly defined licenses!

Hi Tom,

I am new to ZK. But I am going to using ZK with Spring Framework. Should I download the v5 enterprise edition since I saw ZK Spring in this verison. How come if I want to using v5 enterprise ZK freely? What's your suggestion? Should I change to back version 3.6.3 enterprise version for free usage?

Thanks
