There is currently an interesting discussion happening on the LinkedIn “Internet of Things (IoT)” group. It was triggered by the analyst reports I posted a little while back.
The discussion can be found here. Because the “IoT” group is moderated you need to sign up to view the discussion, so I am copying my reply below as well.

Post to the LinkedIn “Internet of Things (IoT)“:
Hi all,
(Disclosure: I am the product manager for Oracle’s small embedded Java products, so my view is probably somewhat biased ;-):
Thanks for an interesting discussion. It highlights the underlying issue in the embedded space: The fact that the industry is fragmented by a diverse mix of technologies that makes delivering embedded solutions much harder than is should be.
It’s not just about choosing a language or a chip architecture. To build an embedded device, you need to integrate hardware components, operating systems, drivers, tools, libraries, security aspects, and more. And increasingly, embedded solutions must be connected and integrated with other systems. So now you need to think about connectivity, protocols, encryption, authentication, data formats, and such. And you’re still not done: What about monitoring and managing these devices out in the field? You need to be able to maintain these devices and update the software to fix issues and add functionality without impacting the integrity of the system. And finally, if you then want to re-use your solution for a different use case and a different set of hardware – do you have to port, integrate, and test everything again?
I think it’s clear that this mode of operation is unsustainable. Yes, you can build all this today using traditional embedded technologies, but it is way too difficult. The important thing to realize is that many embedded use cases must solve a common set of problems as outlined above. The embedded industry will migrate away from individual point solutions towards standards and platforms that address these shared infrastructure requirements. Which then allows developers to add their value on top and deliver solutions quickly and cost effective. This is not unique to the embedded industry but it is a typical pattern of IT evolution.
So when you’re evaluating Java for the embedded space, it’s important to look at it not as just a language, but as a technology platform and ecosystem. Java not only addresses many pain points in embedded development (platform-independence, rich language and feature-set, great tools, scalability) but also gives you a robust and manageable application platform, security framework, connectivity, a wide range of protocols, 3rd party components, and easy integration with back-end systems (most of which are also Java-based). In fact, it is the only technology platform today which is in a position to provide all this.
A few words about Java on the device side:
Not sure if you have been following embedded Java lately – it’s not your father’s Java anymore. You can run feature-rich Java stacks from low-cost micro-controllers with as little as 128 KB RAM all the way up to high-end embedded systems. There is increasing integration with many advanced platform features, as well as out-of-the box support for security, manageability, and back-end connectivity.
Since Oracle announced it’s new focus and strategic vision on embedded Java at JavaOne in September we’re seeing a huge amount of interest in the industry. Oracle has delivered new products and an updated embedded Java roadmap, partners like Cinterion and Qualcomm have announced products, and there is much more to come.
Best regards,

It might have gone unnoticed to some, but Java ME took a big leap forward a couple of weeks ago with the filing of two new JSRs:
- JSR 360: “Connected Limited Device Configuration 8” (aka CLDC 8)
- JSR 361: “Java ME Embedded Profile” (aka ME EP)
Together, these two JSRs will significantly update, enhance, and modernize the Java ME platform, and specifically small embedded Java, with a host of new features and functionality.
JSR 360 – Connected Limited Device Configuration 8
CLDC 8 is based on JSR 139 (CLDC 1.1) and updates the core Java ME VM, language support, libraries, and features to be aligned with Java SE 8. This will include:
- VM updated to comply with the JVM language specification version 2
- Support for SE 7/8 language features like Generics, Assertions, Annotations, Try-with-Resources, and more
- New libraries such as Collections, NIO subset, Logging API subset
- A consolidated and enhanced Generic Connection Framework for multi-protocol I/O
With CLDC 8, Java ME and Java SE are entering their next phase of alignment – making Java the only technology today that truly scales application development, code re-use, and tooling across the whole range of IT platforms, from small embedded to large enterprise.
JSR 361 – Java ME Embedded Profile
ME EP is based on JSR 228 (IMP-NG) and updates the specification in key areas to provide a powerful and flexible application environment for small embedded Java platforms, building on the features of CLDC 8:
- A new, lightweight component and services model
- Shared libraries
- Multi-application concurrency, inter-application communication, and event system
- Application management
- API optionality, to address low-footprint use cases
With ME EP, application developers will have a modern application environment which allows development and deployment of modular, robust, sophisticated, and footprint-optimized solutions for a wide range of embedded use cases and devices.
Summary
While these JSRs are still under development, it’s clear that there are exciting new times ahead for Java ME – turning into a serious application platform while maintaining the focus on resource-constrained devices to address the expected explosion of small, smart, and connected embedded platforms.
To learn more, click on the above links for JSR 360 and JSR 361. Or review the JavaOne 2012 online presentations on the topic:
Also, for more information on JSR 360, check out Roger Brinkley’s blog “A Look inside JSR 360”.
And stay tuned for more in this space!

The Internet of Things (IoT) is coming. And, with todays launch of the Oracle Java ME Embedded 3.2 product, Java is going to play an even greater role in it.
Java in the Internet of Things
By all accounts, intelligent embedded devices are penetrating the world around us – driving industrial processes, monitoring environmental conditions, providing better health care, analyzing and processing data, and much more. And these devices are becoming increasingly connected, adding another dimension of utility. Welcome to the Internet of Things.
As I blogged yesterday, this is a huge opportunity for the Java technology and ecosystem. To enable and utilize these billions of devices effectively you need a programming model, tools, and protocols which provide a feature-rich, consistent, scalable, manageable, and interoperable platform.
Java technology is ideally suited to address these technical and business problems, enabling you eliminate many of the typical challenges in designing embedded solutions. By using Java you can focus on building smarter, more valuable embedded solutions faster. To wit, Java technology is already powering around 10 billion devices worldwide.
Delivering on this vision and accelerating the growth of embedded Java solutions, Oracle is today announcing a brand-new product: Oracle Java Micro Edition (ME) Embedded 3.2, accompanied by an update release of the Java ME Software Development Kit (SDK) to version 3.2.

JavaOne is only 6 days away… Are you ready?
Man, what a crazy couple of weeks it has been. Haven’t blogged for ages. Insanely busy with preparations for JavaOne, Java Embedded @ JavaOne, and some new products we’re working on (on the latter, stay tuned …).
There is so much activity, information, and data around JavaOne to choose from – it’s hard to stay on top of it all. I’ll try to keep it short and provide the highlights as well as my embedded point of view. Ok, here it goes:
First, in case you may not know, there are actually two (!) Java conferences this year: JavaOne itself, and Java Embedded @ JavaOne.
- JavaOne happens from Sep 30 through Oct 4 (yes, that means keynotes are on Sunday! Don’t miss them)
- Java Embedded @ JavaOne happens Oct 3 and 4 – in parallel to JavaOne
Java Embedded @ JavaOne
Why a dedicated conference for Java in embedded? Basically, we believe Java is the perfect platform for embedded solutions, and if you go by any one of the current predictions then smart, small, and connected systems will explode over the next 5 to 10 years. A huge opportunity for the Java ecosystem.
For a quick intro, check out the video “Join us at Java Embedded @ JavaOne” with Judson Althoff, SVP, Worldwide Alliances and Channels.
Henrik Stahl, Senior Director of Product Management, does a great job of introducing Java Embedded @ JavaOne.
Finally, if you have more questions, check out my FAQ on the Java Embedded @ JavaOne conference.
JavaOne
As every year, JavaOne will be packed with keynotes, technical sessions, BOFs, Hands-On-Labs (HOLs), demo grounds, and events.
New for this year are tutorials, which are a mix between an extended technical session, a BOF, and a HOL. It gives the presenters extra time to show you the ropes on a particular topic and extra time for the attendees to ask questions. But it is less of a ‘lab’ setting compared to a HOL. Should be a good addition to the JavaOne structure.
Also new this year is the Oracle OpenWorld Music Festival, which happens throughout the conference (Sun-Thu) in a couple of venues around the main event area. There is music every day and a great line-up of performers such as Macy Gray, Jimmy Cliff, The English Beat, Joss Stone, and many more. Definitely worth checking out. Of course, there is the traditional assortment of parties and events – just check the JavaOne home page!
In terms of embedded, there will be a HUGE focus on that topic at this year’s JavaOne. Oracle is making a big push for Java in the embedded space, not just by launching the Java Embedded @ JavaOne conference (see above), but embedded is embedded (pun intended!) all throughout JavaOne itself:
- Dozens of dedicated embedded technical sessions, BOFs, tutorials, and Hands-on-Labs – ranging from tiny embedded devices through complex end-to-end embedded solutions and touching on a range of different use cases and markets
- Java in embedded spreads throughout the pavilion and demo boths
- Embedded technology featuring in JavaOne keynotes (very cool – see for yourself!)
- Involvement of partners specializing in embedded solutions built on Java
Last, but not least, I will be doing 2 technical sessions at JavaOne, one business session at Java Embedded @ JavaOne and managing one of the embedded Java demo booths with some cool new technology … and probably be involved in a dozen other things as well! If you are at JavaOne this year, you will be hard-pressed to avoid me 😉
Registration for Both Events
There is still time to benefit from the pre-event registration prices. Check out the registration pages (JavaOne, Java Embedded @ JavaOne).
Special price breaks are available for students (FREE! see here), as well as for attendees of JavaOne (only $100 extra to add a full pass for the Java Embedded @ JavaOne conference).
And More …
Finally, don’t just take my word on JavaOne and Java Embedded @ JavaOne:
- JavaOne Conference Preview
- Architects and Architecture at JavaOne
- JavaOne Gangnam Style
- Simon Ritter on JavaOne
- JavaOne Countdown, Are You Ready?
- 25 Reasons to attend JavaOne 2012
- Martin and Lewis at JavaOne 2012?
Ok, that’s it. See you on Sunday in San Francisco!
Cheers,
— Terrence
