To be fixed by #24802

The original file is still here: https://javaee.github.io/glassfish/downloads/quickstart/hello.war
It's very simple, just 2 simple JSP pages and one GIF with Duke. It should easy to create a similar app.

Here's what I suggest:

1. Create a hello WAR maven project in https://github.com/eclipse-ee4j/glassfish/blob/master/docs directory and add it to the maven build (as module of the parent project)
2. Add the hello.war to the glassfish.org page, e.g. to glassfish.org/downloads - in the https://github.com/eclipse-ee4j/glassfish/blob/master/docs/publish/pom.xml, the web site build needs to pull the hello.war maven dependency and place it in ${site.output.dir}/downloads/quickstart
3. Fix the link in the Quick Start guide to point to https://glassfish.org/downloads/quickstart/hello.war
