Oracle has announced the general availability of the latest releases to Java ME Embedded 3.3 and Java ME Software Development Kit (SDK) 3.3, a complete client Java runtime and toolkit optimized for microcontrollers and other resource-constrained devices. This release includes improvements of interest to developers, including ways to not have to build so much "core plumbing" for an app, and more information about memory and network usage, which can be critical for low-power apps.
Java ME Embedded 3.3 includes:
- Binary implementations for popular development boards: Oracle Java ME Embedded 3.3 binaries are freely available available for download from OTN for development and testing for ARM architecture-based developer boards, including the low cost and popular Raspberry Pi, or the Keil Evaluation Board, both accessible from the Java ME SDK 3.3.
- Strong support for market-leading Embedded chip architectures: from ARMv5 through to ARMv7.
- Significant improvements for device APIs: increases the range and number of external peripherals that can be integrated and addressed by applications built on Oracle Java ME Embedded 3.3. IO access now includes APIs for UART, ADC/DAC and AT commands, of particular relevance for wireless modules. This reduces amount of "core plumbing" that developers need to build before they can build their applications and services.
- Significant improvements in run-time monitoring (Memory Status and Network activity) and logging.
- an API to Oracle Java ME Embedded 3.3 that allow access to detailed logs, providing forensic insight into what happened at certain points of the application execution
Oracle Java ME SDK 3.3 includes:
- New support for Microsoft Windows 7 32-bit and 64-bit, in addition to Microsoft Windows XP 32-bit.
- Java ME SDK plug-ins for the NetBeans Integrated Development Environment (IDE) and Eclipse, enabling more application development environments for Java ME developers.
- Emulation of external peripherals and connectivity; e.g. Java ME SDK 3.3 will emulate the wireless access point, along with peripherals such as ADC/DAC, pulse counter, and power management to expedite the time to 'code complete' and reduce the time and cost of application testing.
- In-field and remote administration and debugging.
Oracle Java Platform Integrator Program
Oracle is also introducing the Oracle Java Platform Integrator program to provide partners with the ability to customize Oracle Java ME Embedded products to reach different device types and market segments.

|Yours Truly Generating Data|
Ever pay to have someone watch you sleep? I have. It's not as kinky as it sounds; because of my loud snoring, my spouse insisted I get a sleep study. There I was, in a room with a camera, hooked up to a diagnostic sleep system. I had sensors attached to my head, neck, legs and chest. I even had an ET finger that glowed red (a sensor using light to determine how much oxygen was in my blood). And what was I thinking about as I drifted off to sleep? The data I was generating! Where was it going? What format was it in? Who wrote the app?
There is lots of data being generated by medical devices currently, and much, much more to come. The number of mobile connected devices is expected to increase by 100% to nearly 12 billion by 2020; resulting in a market opportunity of $1.2 trillion. Now what? Where does the data go? What format does the data need to be in? Will developers have to write an different app for every device manufacturer? Java to the rescue! Manfred Kube, Director of Business Development, mHealth, for Gemalto Systems explains, "Through the power of Java, we are enabling medical devices to connect to cloud in a standard-based, interoperable fashion, and avoid the silos that are common today." See how Java makes it easy to get started and be successful in mHealth:
The GMSA supports standards throughout the mobile world, and is taking the lead in M2M standards. To accelerate and simplify mobile health application development, the GMSA is partnering with the Continua Health Alliance, whose mission is to developing design guidelines that will enable vendors to build interoperable sensors, home networks, telehealth platforms, and health and wellness services.

The Developer's Conference (TDC) kicked off Wednesday in São Paulo, Brazil. With over 3000 developers in attendance over five days, it is the premier multi-community developer conference in Brazil, organized by Globalcode. Yara Senger, one of the organizers said, "We like to say multi-community rather than multi-technology because it is interesting and benefical when various communities get together. They learn so much from each other!" TDC includes tracks on Java and several other technologies, including SOA, Python, Ruby, mobile and digital TV. In the mobile track, developers who create a Java ME app will get a Nokia S40 phone!
New this year at TDC is the Java University track, sponsored by Oracle. It is aimed at university students and professionals who are new to Java. The lectures are introductory level, with an educational focus and practical exercises. The Java track and other tracks, such as SOA, mobile and Digital TV, are getting lots of help from the expertise of Brazilian JUGS members. Thanks to GoJava, JavaBahia, JavaNoroeste and SouJava!
Carlos Fernando, one of the coordinators on the Digital TV track, said "My goal is to teach developers the basics of digital TV, and show them the tools used to build interactive TV applications." Fernando explained the concept of "the second screen:" that many people watch TV and have second smart device (tablet or smartphone) with them, and this creates many opportunities for developers. For example, while watching TV, a viewer can get extra content (interviews, behind the scenes) on their tablet. More interestingly, while watching their favorite TV show a viewer likes an outfit one of the actors is wearing, their smartphone can tell them where they can buy it nearby, or they can order it online immediately. Fernando exclaimed, "The opportunities for developers are nearly infinite in the area of digital TV!"
At the TDC opening keynote, Debora Palermo, Oracle University country manager for Brazil, reminded attendees that Java is present in many devices, from simple to complex, and knowledge of this platform can open many doors in the labor market. She explained Oracle's Workforce Development Program (WDP), managed by Oracle University, which allows educational institutions to deliver Oracle training. WDP allows for easy and low-cost access to Oracle training in local communities across the world. "Oracle University is committed to creating the next generation of Java developers, and WDP can make that happen," Palermo said. As of March 2012, Oracle University is partnering with Globalcode to offer WDP. Students can earn official Oracle Course Certifications, a great way to learn Java.
Brazilian developers that cannot attend TDC can watch live streaming.
