How to change the context url in jboss or wildfly

Normally when we create a new war or ear, for example demo-project.war or demo-project.war inside demo-project.ear. The context root or url to which we can access the web application is:

http://localhost:8080/demo-project

But what if we want to change context root or in this case demo-project to let's say "demo" only.

Steps:
1.) In the web project create a new file: src/main/webapp/WEB-INF/jboss-web.xml

2.) Enter the following content

<jboss-web>
    <context-root>demo</context-root>
</jboss-web>
