source code for https://www.zkoss.org/documentation#Getting_Started

Overview

This is the example application for ZK "Getting Started" articles:

• Learn ZK in 10 Minutes
• Get ZK Up and Running with MVC
• Get ZK Up and Running with MVVM

How to Run

Clone the project and launch your command line interface in the project root folder. Execute the following commands based on your environment.

Maven installed

mvn jetty:run

No Maven installed yet

Run the Maven wrapper below which will download everything needed for you during starting up:

• Linux / Mac

./mvnw jetty:run

• Windows

mvnw.cmd jetty:run

You can press Ctrl + c to stop the jetty server.

With Docker

Assuming you have installed Docker.

1. build an image by docker build -t gettingstarted .
2. run docker run -p 8080:8080 gettingstarted

It will take a while because it needs to download all required jars.

Then visit http://localhost:8080/getzkup/ with your browser.
