Introduction

What we want

Avoid multiple users from editing the same resource simultaneously.

lock / unlock a resource
e.g. obtain and release exclusive access to edit a specific objects properties
observe a resource for owner changes (LockEvents)
it should be possible to observe the same resource with multiple concurrent users
react to LockEvents and update the UI
immediately indicate availability/ownership/unavailability of a resource to the user

The code examples are available on github in the zk-template-examples repository

Clone the repo

   git clone git@github.com:zkoss-demo/zk-template-examples.git

The example war file can be built using the gradle-wrapper (on windows simply omit the prefix './'):

   ./gradlew war

Execute using gretty:

   ./gradlew appRun

Execute using jetty-runner (faster startup):

   ./gradlew startJettyRunner
