ZK Framework is offered in 3 editions, CE, PE and EE. To see what features are included in each edition, visit the Feature Page.
Upgrade the Library
To upgrade from CE to ZK PE or EE(Evaluation Copy), download the corresponding PE/EE (Evaluation) binary files from the Download Page, or specify the evaluation repository and include required PE/EE dependencies if you use maven. Maven instructions here.
Download instructions for paying customers were given at the time of the purchase. If you are not sure, contact us with your License Certificate Number and we will help.
In addition to the core ZK features, PE/EE users are given access to use certain add-ons and tools according to the package they are on. For example a EE user can use ZATS Mimic, ZK Spring, ThemePack themes and ZK Calendar - they are not packaged in the core ZK. To use these add-ons, you will have to either download the corresponding jar files from their download pages, or, include the dependency in your maven POM file.
Use PE/EE specific components and features
After upgrading to PE/EE, you have access to more components, features and Java classes.
Features enabled by default
After upgrading to PE/EE, some of the features are enabled by default. For example, the client render on demand feature will be enabled by default to improve the client-side performance. Also, with EE, the Tablet UI will be enabled by default, when a tablet or mobile device connects to your application the tablet-supported components will switch themselves to the tablet theme. You can manually disable them in zk.xml if you are not ready.
Change of default behavior
Some of the default behavior changes after you upgraded the ZK edition. For example in the case of server push, with CE, it uses client polling. Once you upgrade to PE, the default push becomes comet push, and with EE it uses servlet 3 comet. Learn more here.
Some PE/EE features are now available for you to use, but you will have to enable them by yourself. For example if you have a big grid or listbox, you can turn on render on demand to boost its performance.
