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.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities. Well-poised organizations, marketing smart devices with AI and BlockChain capabilities prepare to refine compliance and regulatory capabilities in 2018. Volumes of health, financial, technical and privacy data, along with tightening compliance requirements by...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
