From Within the Java Community Process Program

From Within the Java Community Process Program

This month I'll discuss the evolution of the JCP, J2SE 1.5 or "Tiger", Java portlets, and a new JSR from Nokia and Siemens.

JSR 215, aka JCP Version 2.6
The Java Community Process is the only standards body with a version number! Currently, we're at 2.5 and hope to soon be at 2.6. Where are we now? About halfway between 2.5 and 2.6. Rule and regulation changes in the JCP happen through the JSRs. JSR 913 modified the JSR ballot voting rules, JSRs 99 and 171 led to JCP 2.5, and JSR 215 is creating JCP 2.6. This JSR just completed the Community Review and ballot. The Program Office together with the Executive Committees will now be working toward Public Review. A few of the things the group will focus on are clarifications around JSRs assigned to both ECs, a draft transparency plan for spec leads to use, and ironing out the mandatory TCK requirements. While the Community Review period has passed, the draft is still available on the Web site and you can send in your thoughts and ideas. Speaking of evolution, at the end of this year the JCP will be five years old. The Program Office will be at ApacheCon in November to celebrate. Now, on to the real work in the community!

A Tiger in Review
The three main Java platforms (J2ME, J2SE, and J2EE) are all done through the JCP. The coordination for these main releases takes place through so-called Umbrella JSRs. The actual API work for a new version of J2SE or J2EE does not happen in the Umbrella JSR. Instead the Umbrella JSR references the individual JSRs that specify new and updated APIs. Many of the JSRs that contribute to J2SE 1.5 or "Tiger" have just completed their Community Reviews. See JSR 176, the J2SE 1.5 Umbrella JSR, for a complete list of component JSRs. I covered a few of these JSRs in previous columns. Here I'd like to mention JSRs 3, 13, 199, 204, and 206. With "Tiger" the Java Management Extension specification becomes part of the J2SE distribution. JSR 13 adds floating point arithmetic to BigDecimal so that decimal numbers can be used for general purpose arithmetic without the need to convert to and from other types. The Java Compiler API enables a Java program to invoke a Java language compiler programmatically. JSR 204 further enhances the internationalization capabilities of the Java platform by providing support for the Unicode 3.1 standard. Unicode 3.1 defines characters that cannot be described by single 16-bit code points. Finally, there is JSR 206, which is developing JAXP version 1.3, an API for processing XML.

The Java Portlet Specification
This JSR, number 168, is co-led by IBM and Sun. The JSR resulted from a simultaneous submission of two quite similar JSRs individually presented by both companies. At the urging of the EC, IBM and Sun withdrew those individual JSRs and submitted a combined one, JSR 168. The JSR recently posted in short succession two Proposed Final Drafts, and it's very likely that by the time you read this column the JSR will be on the Final Approval Ballot. This specification builds on the servlet technology by defining the desktop metaphor for the aggregation of servlets and JSPs. It also covers security and personalization, and enables interoperability between portlets and portals.

JSR 228
Nokia and Siemens recently finalized JSR 195, Information Module Profile. This was quickly followed by the submission of JSR 228 that defines Information Module Profile - Next Generation. The technology is aimed at devices that want to support a MIDP 2.0 environment but don't provide any graphical display capabilities required by MIDP 2.0. JSR 195 first opened this market for Java-enabled devices, such as modems, metering, and home electronics. This created a strong desire for the advanced capabilities of MIDP 2.0. JSR 228 will focus on the domain security model, HTTPS and secure networking, OTA provisioning, and push architecture. The spec leads aim to finish the JSR in the late spring of 2004.

That's it for this month. I am very interested in your feedback. Please e-mail me with your comments, questions, and suggestions.

The widespread success of cloud computing is driving the DevOps revolution in enterprise IT. Now as never before, development teams must communicate and collaborate in a dynamic, 24/7/365 environment. There is no time to wait for long development cycles that produce software that is obsolete at launch. DevOps may be disruptive, but it is essential.
The Industrial Internet revolution is now underway, enabled by connected machines and billions of devices that communicate and collaborate. The massive amounts of Big Data requiring real-time analysis is flooding legacy IT systems and giving way to cloud environments that can handle the unpredictable workloads. Yet many barriers remain until we can fully realize the opportunities and benefits from the convergence of machines and devices with Big Data and the cloud, including interoperability, data security and privacy.
Wearable devices have come of age. The primary applications of wearables so far have been "the Quantified Self" or the tracking of one's fitness and health status. We propose the evolution of wearables into social and emotional communication devices. Our BE(tm) sensor uses light to visualize the skin conductance response. Our sensors are very inexpensive and can be massively distributed to audiences or groups of any size, in order to gauge reactions to performances, video, or any kind of presentation. In her session at @ThingsExpo, Jocelyn Scheirer, CEO & Founder of Bionolux, will discuss ho...

In his session at @ThingsExpo, Sean Lorenz, Technical Product Manager for Xively at LogMeIn, demonstrated how to approach creating broadly successful connected customer solutions using real world business transformation studies including New England BioLabs and more.
Since 2008 and for the first time in history, more than half of humans live in urban areas, urging cities to become “smart.” Today, cities can leverage the wide availability of smartphones combined with new technologies such as Beacons or NFC to connect their urban furniture and environment to create citizen-first services that improve transportation, way-finding and information delivery. In her session at @ThingsExpo, Laetitia Gazel-Anthoine, CEO of Connecthings, will focus on successful use cases.
Enthusiasm for the Internet of Things has reached an all-time high. In 2013 alone, venture capitalists spent more than $1 billion dollars investing in the IoT space. With "smart" appliances and devices, IoT covers wearable smart devices, cloud services to hardware companies. Nest, a Google company, detects temperatures inside homes and automatically adjusts it by tracking its user's habit. These technologies are quickly developing and with it come challenges such as bridging infrastructure gaps, abiding by privacy concerns and making the concept a reality. These challenges can't be addressed w...
The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...
The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...
"For over 25 years we have been working with a lot of enterprise customers and we have seen how companies create applications. And now that we have moved to cloud computing, mobile, social and the Internet of Things, we see that the market needs a new way of creating applications," stated Jesse Shiah, CEO, President and Co-Founder of AgilePoint Inc., in this SYS-CON.tv interview at 15th Cloud Expo, held Nov 4–6, 2014, at the Santa Clara Convention Center in Santa Clara, CA.
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...
The industrial software market has treated data with the mentality of “collect everything now, worry about how to use it later.” We now find ourselves buried in data, with the pervasive connectivity of the (Industrial) Internet of Things only piling on more numbers. There’s too much data and not enough information. In his session at @ThingsExpo, Bob Gates, Global Marketing Director, GE’s Intelligent Platforms business, to discuss how realizing the power of IoT, software developers are now focused on understanding how industrial data can create intelligence for industrial operations.
