Feature comparison
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, download the corresponding PE/EE binary files from the Download Page, or specify the evaluation repository and include required PE/EE dependencies if you use maven. Maven instructions here.
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.
Reference the Feature Page to see what features are covered in PE/EE and reference the content (jar) of binary distributions to see what comes in the core package.
Use PE/EE specific components and features
After upgrading to PE/EE, you have more components, features and Java classes to use.
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/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 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. Read more here.
Require configuration
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.
Please reference corresponding documentation for the relevant configurations or contact info@zkoss.org if you have any questions.
