IoT, Mobility and Cloud Integration Hands-On: Controlling Raspberry Pi GPIO Using Oracle MAF App and Oracle ADF Application Deployed on Oracle Java Cloud Service (Part I)

Internet of Things ecosystem is continuously changing our world and opening a New Digital Era for business. Billions of different sensors on millions of devices collecting information on everything from automobile performance to energy use, crop development, calories burned, and just about anything else one might want to measure, the IoT contains more information about the world around us than we’ve ever had access to before.

In this article I will consider simple but real-life example of IoT, Mobile and Cloud integration: how to control IoT device using mobile application and web-application deployed on Oracle Cloud. We will use Raspberry Pi 2 Model B single board computer as IoT device where business logic is simple: toggling a light-emitting diode(LED) (switching on/off). In order to control LED we will develop mobile application using Oracle MAF and web-application using Oracle ADF framework. Finally we will deploy our web-application on Oracle Java Cloud Service.

Oracle Enterpise for Eclipse (OEPE) in an existing Eclipse installation

Oracle's developer tools strategy is to offer the best possible developer tools choices to support diverse needs. When it comes to Java IDEs, while JDeveloper is Oracle’s owned developed Java IDE, Oracle covers Java 100% offers the industry's most complete array of Java IDEs.

Eclipse IDE is considered an essential tool by many Java EE Developers and we realize that many are actively using it and would prefer to continue to use it. It takes a long time to produce applications and maintain them, so developers are always looking to be more “agile”, especially nowadays with changing budgets and development strategies. There for the Java IDE being used is not just a matter of preference, but also efficiency and fast delivery.

Oracle Enterprise Pack for Eclipse 12c (OEPE) provides an unparalleled development experience for Eclipse developers looking to create Java, Mobile (see webcast here ), and Web Enterprise Applications leveraging Oracle's Java and Middleware, Mobile, Database and Cloud Platforms.

The latest Oracle Enterprise Pack for Eclipse 12c ( release,

But sometimes we may encounter problems which do not seem to be obvious in terms of how to solve them.

In this post I would like to share some of my experience in integrating JEE world into the ADF application.
