Source Code

All source codes used in this book are available on github. As our example application has 3 different configurations, our source code is divided into 3 branches:

  • master: contains examples from chapter 1 to chapter 7.
  • zk-spring: has examples integrated with Spring
  • zk-jpa: contains examples which integrate with Spring and persiste data into a database with JPA.

You can click the "ZIP" icon to download the current selected branch as a zip file.

Run Example Application

After you download the source code, you will find it is a Apache Maven project with jetty plugin configured. Therefore, you can start the example application on Jetty without deploying.

No Maven Installed

Even you don't install Maven, you can start the project with maven wrapper by the command below (it will automatically download required maven):

Linux/Mac

./mvnw jetty:run

Windows

mvnw jetty:run

With Maven

Navigate to the root folder of the example project, e.g. it's "zkessentials" and type the command:

mvn jetty:run

With Gradle

You have 2 options:

  • Start with the gradle plugin gretty

gradle appRun

  • Start with embedded jetty-runner that we configured in build.gradle

gradle startJettyRunner

After starting up, visit the URL http://localhost:8080/zkessentials/, and you should see the page below:

Project Structure

The example project's folder structure follows Maven's default convention. We name Java packages according to each chapter, and each package contains the classes of that chapter. Some common classes are separated to an independent package as they are used in multiple chapters, e.g. the classes under org.zkoss.essentials.entity.* are entity class. We also define some service layer interfaces under org.zkoss.essentials.service.* because different chapters have different implementations.

For ZUL pages, we put them in separate folders for each chapter under src/main/webapp/. Under "WEB-INF" folder, web.xml contains minimal configuration to run ZK and for its detail please refer to ZK Installation Guide \ Create and Run Your First ZK Application Manually. The "zk.xml" is optional configuration descriptor of ZK. Provide this file if you need to configure ZK differently from the default behavior. Refer to ZK Configuration Reference/zk.xml for more detail.
