It has decent documentation and relatively steep learning curve. It also provides free hosting + free MySQL DB up to 1 GB, which is aweosome!

After installing Ruby and RHC - Openshift’s client tool, by following these steps, you can start creating a Java web application following these steps.

Habit@weave

Habit@weave is a web application for the control and monitoring smart homes and wearable devices. The power consumption graphs and the capability to schedule actions can help the user to make the right decisions for efficient energy saving at home, while the calorie consumption and sleep quality charts may contribute to adoption of habits that improve heath. The user can use the application from a PC, as well as from any other portable device with access to the Internet. It is an initial effort towards a functional Ambient Assisted Living system. It’s also a good starting point for any Java web application with Hibernate JPA and Shiro security frameworks.

Demo

A demo of the application’s runs here http://habitat-atsamour.rhcloud.com. To try the application use these credentials:

  • E-mail: test2@gmail.com
  • Password: 1234

Source

The application’s git repo is here. You can find the sample database used in the application at the amazon cloud (add a database named awesomedb to the OpenShift MySQL Cartridge and import tables there).

The folders are organized as a Maven project. Backend is written in Java using javax.servlet API, frontend is based on Bootstrap and implemented with JSP views.

]]>Heroku Java examplehttp://arkadios.me/post/heroku-java-example/Mon, 10 Aug 2015 00:00:00 +0000Arkadios Tsamourliadishttp://arkadios.me/post/heroku-java-example/Here https://github.com/atsamour/Heroku-java-example you can find a sample Java web project for Heroku PaaS cloud. You can also run it locally with only JRE and Maven installed, as it doesn’t requre a seperate application container. It evaluates Heroku’s open source with embedded Tomcat.

To run locally

First you have to git pull the repo to your PC, then build the application running this command from the local project folder:

:::term
$ mvn package

And then you just run the application by using the java command:

:::term
$ java -jar target/dependency/webapp-runner.jar target/*.war

If everything worked correctly, your application should be accessible at localhost:8080.

To run on Heroku cloud

First create a Heroku account, install Heroku Toolbelt as described here, then deploy the app on Heroku as described here. If everything worked correctly, your should see the application in your browser.

To deploying a jar filer that doesn’t exist at Maven repository

Download and put the .jar (e.g.) file to the project’s folder (e.g. C:\Users\username\Dropbox\heroku-examples\appfolder) Then call mvn deploy:deploy-file to actually deploy the jar to repo folder:

:::term
mvn deploy:deploy-file -Durl=file:///C:\Users\username\Dropbox\heroku-examples\appfolder\repo\ -Dfile=json-taglib-0.4.1.jar -DgroupId=atg.taglib.json -DartifactId=json-taglib -Dpackaging=jar -Dversion=0.4.1

You are ready to add this dependancy to your main pom file as any other. more info here: https://maven.apache.org/guides/mini/guide-3rd-party-jars-remote.html, https://devcenter.heroku.com/articles/local-maven-dependenciess
