Demo App

The Demo app provides an introduction to the Apache Causeway programming model, allowing you to learn the basics with a minimum of hassle. It’s also a useful reference to help you develop your own Apache Causeway applications.

The application is packaged up as a Docker image (apachecauseway/demo-wicket-jdo or apachecauseway/demo-wicket-jpa) on Docker Hub, so you can easily run it yourself (as described below). You can see also try out the application online, jdo or jpa.


Head over to Docker to install the community edition.

Running the Docker Image

Assuming the jdo variant (if using jpa, just substitute "jdo" with "jpa" in the commands below):

  • Pull the Demo image

    docker pull apachecauseway/demo-wicket-jdo:latest
  • Running the Docker Image

    docker pull apachecauseway/demo-wicket-jdo:latest
    docker run -d -p8080:8080 apachecauseway/demo-wicket-jdo:latest

    The Demo app can then be accessed at http://localhost:8080/wicket/. Login with sven:pass.

  • Stop and remove the container named demo

    docker stop demo && docker rm demo


The way in which the app is run by Docker be customised in a couple of ways. Assuming the jdo variant (if using jpa, just substitute "jdo" with "jpa" in the commands below):

  • Prototyping mode

    docker run -d -p8080:8080 -ePROTOTYPING=true apachecauseway/demo-wicket-jdo:latest
  • Attached console

    docker run -it -p8080:8080 apachecauseway/demo-wicket-jdo:latest

    Use CTRL-C to stop and detach

    on Windows, you might need to prefix with winpty.
  • Specify a different context Path

    docker run -d -p8080:8080 -eContextPath=/myPath apachecauseway/demo-wicket-jdo:latest
