Heroku

In this article we’ll create a simple Jersey application deploy it in Jetty servlet container and everything will be hosted on Heroku.

Create an Application

To create a skeleton of Jersey 2 web-app that can be run on Heroku from the jersey-heroku-webapp archetype (available since Jersey 2.5), execute the following Maven command in the directory where you want the new project should be located:

mvn archetype:generate -DarchetypeArtifactId=jersey-heroku-webapp \
    -DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
    -DgroupId=com.example -DartifactId=simple-heroku-webapp -Dpackage=com.example \
    -DarchetypeVersion=2.5.1

Adjust the groupId, package and/or artifactId of your new web application project to your needs or, alternatively, you can change it by updating the new project pom.xml once it gets generated.
