A barebones Java app with Salesforce OAuth 2.0 Web Sever Flow implemented, which can easily be deployed to Heroku.
This application is based on the Getting Started with Java on Heroku article - check it out.
Make sure you have Java and Maven installed. Also, install the Heroku Toolbelt.
$ git clone https://github.com/heroku/java-getting-started.git
$ cd java-getting-started
$ mvn install
$ heroku local:start
Your app should now be running on localhost:5000.
If you're going to use a database, ensure you have a local .env
file that reads something like this:
DATABASE_URL=postgres://localhost:5432/java_database_name
$ heroku create
$ git push heroku master
$ heroku open
