Since 2005, ZK has been known for its "Ajax without JavaScript" approach, allowing developers to build rich internet applications without needing knowledge of Ajax or JavaScript.

In ZK, the client engine acts as the pitcher, and the update engine as the catcher, making Ajax communication invisible to the developer. When users trigger events by interacting with UI, ZK automatically encapsulates and sends them to the appropriate event listeners.

User interfaces are rendered in the browser but represented on the server as Plain Old Java Objects (POJO) components. Any changes made to these server-side POJO components are automatically synced to the client-side interface.

By running code on the server, developers can fully utilize Java technologies such as Java EE and Spring, making it easy to access backend data and services.

ZK's Server+client Fusion gives developers the freedom to leverage the best of both sides.

The server-centric solution to Ajax brings a productivity boost, robustness, and security to Web application development; while client side solutions endows Web applications with greater controllability and the ability to leverage client side resources.

ZK marries the benefits of both to bring forth a developer-centric approach where developers continue to build large scale enterprise applications with all the robustness of Java technologies, but also are offered the flexibility to work directly with ZK's jQuery based widgets to further enhance user experience.

ZK User Interface Markup Language (ZUML) makes the design of rich user interfaces as simple as authoring HTML pages. ZUML is a variant of XUL inheriting all features available to XML, and separates the UI definition from the run-time logic.

ZUML also allows developers to automate CRUD between UI components and the data source with annotations, data binding and MVVM.

• run bin/upver.sh to update version number in all pom.xml files.
• We recommend you to use a different version number from the official release version to distinguish it from the official release, e.g. add a suffix "-xyz".

• run ./gradlew clean build -x test -x tscheck -x jscheck -PcleanZKOnly=true -PbuildZKOnly=true
• Need to run gradlew to ensure using the expected gradle version
• -x tscheck -x jscheck : skip these checking because they requires ZK EE modules

• run ./gradlew publishToMavenLocal
