Develop Java Applications Using a Raspberry Pi

Ready to dive into the Internet of Things? Take the new, free, online course "Develop Java Embedded Applications Using a Raspberry Pi." The Oracle Learning Library has created this course which provides code, examples, and experts to teach you and answer your questions.

Java experts Stephen Chin, Jim Weaver, Simon Ritter, Angela Caicedo, and Tom McGinn will lead you through basic exercises. Each week, you'll get a new set of course materials:

  • A series of short, pre-recorded videos provide the "lecture" portion of the course.
  • A homework project is linked to the video material, and applies what you have learned by working with Java ME Embedded, the Raspberry Pi, and some electronic components.
  • A graded quiz evaluates how well you have grasped the materials and the homework.

Order your equipment now so you can have it in time for the course start on March 31st!

Here are a few FAQs (You can send questions or comments to Java-MOOC-Support.)

Q: Is the course free or do we have to pay for it?

A: The course is free. There is hardware you have in order to complete the labs (homework) but the course materials are free.

Q: It starts end of March and goes on for five weeks, but how often / how long will sessions occur? 5x 1hour? Or 25 full days? At what time will the sessions occur? 

A: This course is delivered entirely on-line.  There are no set times for sessions because the training is in pre-recorded video that you can watch anytime, anywhere.  Each week Oracle will release the materials for that week, and you should expect to spend between 4 and 6 hours each week on the lessons, the labs and the quizzes.

Q: Is there anything special about the kit (e.g. parts that are just for the MOOC that you wouldn't normally be able to buy)? 

A: The parts for the MOOC are only special in that they represent the use case presented by the course, that of an asset management system designed to provide data on container shipments of fresh produce: container door access (switch), temperature (I2c), global position (UART), and of course a RaspberryPi and breadboard as the development platform. The devices are available through Adafruit and relatively inexpensive.

Getting Started with Oracle Java ME Embedded 3.3 on the Keil Evaluation Board

The new release this week of Oracle Java ME Embedded 3.3 for ARM Cortex M3 make the Oracle Java ME Embedded product available as a reference binary for the Keil MCBSTM32F200 platform for development/evaluation purposes. This binary comes integrated with RTX OS. To help you get up and running, Oracle Java Evangelist Angela Caicedo has created a new two part video that shows you all the steps you need to follow to develop your first applications using Java ME Embedded 3.3 on the Keil evaluation board.

Video: Getting Started with Java ME Embedded 3.3 Part One


   Part I

This new tutorial video provides the step-by-step guide to get Oracle Java ME Embedded for ARM Cortex M3 up and running on the on Keil evaluation board: from the configuration of the software and hardware, and how to    test; how to connect to the command line and logging interfaces; and of course how to get started with this Java ME Embedded application. Angela walks us through how to install, update and even uninstall the application.


Video: Getting Started with Java ME Embedded 3.3 Part Two


Part Two

In the second video, Caicedo uses Netbeans 7.3 with Oracle Java ME SDK 3.3 NetBeans Plugin, Java ME SDK 3.3 (early access) and the Oracle Java ME Embedded 3.3 for ARM Cortex M3/RTX software distribution to create an embedded application, run it on an emulator and provides tips on how you can debug your application. Then using these tools you will be taken through the steps to create your first application, deploy it, and test that everything is running properly.

Oracle Java ME Embedded 3.3 complete product functionality such as peripheral IO, AMS operations, headless operations, functionality for remote application management/configurability, etc. is available on the Keil MCBSTM32F200 platform. Download and see the documentation on OTN to learn more.

Java in the Internet of Things

In this video, I talk to Product Manager for Small Embedded Java Terrence Barr at Embedded World. He gave presentations that included the slide that said "Stop Reinventing the Plumbing." I asked him what that means:

Java already has the connectivity, manageability, interoperability, and back-end integration you need for apps, so you can concentrate on your area of expertise, your "value add" on top of that plumbing. Java -- saving the world, one developer, one sensor at a time. ;-)
