JSR Bookmarks Presented by the Spec Leads

Interested in getting the latest on Java technology standards at the 2007 JavaOne Conference?

Interested in getting the latest on Java technology standards at the 2007 JavaOne Conference? A great opportunity is awaiting you because the show has a lot to offer this year too. There are over 60 events - technical sessions (TS), Birds-of-a-Feather meetings (BOF), and Hands On Labs - based on Java specifications developed or in development through the JCP. Here are a few of them presented by none other than the Spec Leads.

JSR 296: The Swing Application Framework is the topic of TS-3942. Joshua Marinacci and Hans Muller, both of Sun Microsystems, will present the advantages developers will be able to draw from having a standard architecture for desktop applications included in the Java platform. At the end of its development road, this specification will define a simple application framework for Swing applications. Another Swing-related session is Swing in a Multithreaded World, TS 3565, from which you will learn about best practices and common patterns in writing multithreaded desktop applications.

Another JSR-based session is TS-4225, What's New in the Java Portlet Specification 2.0 (JSR 286)? IBM's Stefan Hepper and Sun's Wesley Budzjwojski will present the functionality that will be added to the new portlet specifications. If you want to learn about the major new concepts, such as coordination between portlets, serving resources through the portlet, supporting AJAX use cases with portlets, portlet filters, and validation-based caching, plan to attend. The session will also cover other small but important changes and the alignment with the new version of Web Services for Remote Portlets (WSRP 2.0) and Web frameworks such as JavaServer Faces technology.

If you are into developing mobile applications that integrate Web services or are planning to start, bookmark TS-5188 Web Services to Go: Mobile Access to Web Services with JSRs 279 and 280. Spec Leads from Nokia and BenQ will present how JSRs 280 (XML API for Java ME) and 279 (Service Connection API for Java ME) will help with interacting with Web services from mobile devices by adding platform support for XML and Web services, creating a new mobile Web services ecosystem. JSR 280 provides a general-purpose API for XML processing, extending JSR 172 and adding Streaming API for XML (StAX) and Document Object Model (DOM) parsing. JSR 279 is building on JSR 280's XML API and provides a framework for straightforward access to networked services, incorporating support for service discovery, authentication, and identity.

A project recently submitted to the JCP, JSR 311, will be showcased in TS-6411, The Java API for RESTful Web Services. The spec leads will talk about the goal of the Java API for RESTful Web services, which is to provide a high-level declarative programming model for such services that is easy to use and encourages development. Services built with the API, the spec leads will show, will be deployable by use of a variety of Web container technologies and will benefit from built-in support for a variety of HTTP usage patterns and conventions.

If you're looking for a brief REST primer and an update on the progress of the JSR 311 to date, this is the session for you. The Spec Leads will outline the current API design and highlight issues currently under discussion by the expert group. Live code demonstrations will illustrate the API discussion.

Michal Cierniak, of Google, and Alex Buckley, of Sun Microsystems, partner to bring us a BOF session about the Modularity in the Next-Generation Java Platform, Standard Edition (Java SE): JSR 277 and JSR 294. The two Java Specification Requests (JSRs) are targeted to be delivered as a component of the Java Platform, Standard Edition (Java SE) 7.0. JSR 294 sets out to define the modules for development, and JSR 277 to define the modules for deployment. The specifications set out to address many issues including those associated with Java Archives (JARs), including the lack of version control, the difficulties in distributing multiple JARs for deployment, the classpath hell, JAR hell, and extension hell, and so on, which have been well known to many developers on the Java platform for years.

Gavin King of Red Hat Middleware, Spec Lead, and Bob Lee of Google, Expert Group member, will give a Web Beans update in TS-4089. JSR 299, Web Beans, aims to unify the JavaServer Faces technology-based managed bean component model with the Enterprise JavaBeans (EJB) component model, resulting in a significantly simplified programming model for Web-based applications. The two plan to provide attendees with background on the Web Beans effort, give an update on Expert Group membership, and outline the purpose and scope of the Web Beans specification, the Web Beans programming model, the impact on other JSRs: EJB 3 architecture; JavaServer Faces platform; Java EE. If you are interested in the current status of JSR 299 and the open issues with which the Spec Lead and Expert Group members are confronting themselves, plan to attend this session.

Developers who have tracked Java Business Integration aka JBI will want to bookmark BOF-8872 driven by Peter Walker of Sun and Mark Little of Red Hat Middleware. The session brings together members of the Java Business Integration (JBI) 2.0 Expert Group, members of the Open ESB community, and others interested in finding out more about JBI 2.0 and its progress to date to discuss priorities and directions for work within the context of the JSR. A related technical session is TS-8216, Why do I need JBI when we have BPEL?, presented by Sun's Peter Walker and Andreas Egloff. Expect the session to tackle one of the most popular questions posed to the JBI team at last year's JavaOne Conference: Does JSR 208, Java Business Integration (JBI), compete or overlap with the Business Process Execution Language (BPEL)? The session will also address some common questions and misconceptions about how to best utilize JBI and how different users can get started on benefiting from JBI.

In December 2006 the Spec Leads and Expert Group of JSR 248, Mobile Services Architecture, finalized the standard. At this year's JavaOne, Kay Glahn of Vodafone and Miklos Kelen of Nokia will be presenting the session JSR 248: Taking Java Platform, Micro Edition (Java ME) to the Next Level, showcasing experiences with the completed JSR 248, and covering the specification already published and the status of its industry acceptance. If you want to get a JSR 248 post release update and an overview of the latest 248-compliant mobile devices, then you should plan to attend this session.

If you're looking for a hands-on lab on real-time Java programming, you've got your chance with LAB-7250, The Real-Time Java Programming Challenge: How to Build Real-Time Solutions for Real-World Devices. Greg Bollella and David Holmes, of Sun Microsystems, will demonstrate that Java is ready for real time and will challenge participants to see for themselves by building their own real-time Java application.

The lab is based on JSR 1, The Real-Time Specification for Java (JSR 01), which provides several key application interfaces that enable developers to create programs with predictable timing and deterministic program execution.

This is just a selection of the JSR-based sessions JavaOne has in store for you this year; the list goes on and on. I encourage you to go to the JavaOne Conference page at, click on Content Catalog, and start bookmarking your portfolio of preferred sessions.

@ThingsExpo Stories
Countless business models have spawned from the IaaS industry – resell Web hosting, blogs, public cloud, and on and on. With the overwhelming amount of tools available to us, it's sometimes easy to overlook that many of them are just new skins of resources we've had for a long time. In his general session at 17th Cloud Expo, Harold Hannon, Sr. Software Architect at SoftLayer, an IBM Company, broke down what we have to work with, discussed the benefits and pitfalls and how we can best use them to design hosted applications.
Most of the IoT Gateway scenarios involve collecting data from machines/processing and pushing data upstream to cloud for further analytics. The gateway hardware varies from Raspberry Pi to Industrial PCs. The document states the process of allowing deploying polyglot data pipelining software with the clear notion of supporting immutability. In his session at @ThingsExpo, Shashank Jain, a development architect for SAP Labs, discussed the objective, which is to automate the IoT deployment process from development to production scenarios using Docker containers.
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningful and actionable insights. In his session at @ThingsExpo, Paul Turner, Chief Marketing Officer at...
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Summit, Charles Kendrick, CTO and Chief Architect at Isomorphic Software, demonstrated examples of com...
In his keynote at @ThingsExpo, Chris Matthieu, Director of IoT Engineering at Citrix and co-founder and CTO of Octoblu, focused on building an IoT platform and company. He provided a behind-the-scenes look at Octoblu’s platform, business, and pivots along the way (including the Citrix acquisition of Octoblu).
In his General Session at 17th Cloud Expo, Bruce Swann, Senior Product Marketing Manager for Adobe Campaign, explored the key ingredients of cross-channel marketing in a digital world. Learn how the Adobe Marketing Cloud can help marketers embrace opportunities for personalized, relevant and real-time customer engagement across offline (direct mail, point of sale, call center) and digital (email, website, SMS, mobile apps, social networks, connected objects).
The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development. With the rise of mobile applications in the enterprise, businesses are abandoning year-long development cycles and embracing technologies that enable rapid development and continuous deployment of apps. In his session at DevOps Summit, Kurt Collins, Developer Evangelist at, examined how Docker has evolved into a highly effective tool for application delivery by allowing increasingly popular Mobile Backend-as-a-Service (mBaaS) platforms to quickly crea...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Growth hacking is common for startups to make unheard-of progress in building their business. Career Hacks can help Geek Girls and those who support them (yes, that's you too, Dad!) to excel in this typically male-dominated world. Get ready to learn the facts: Is there a bias against women in the tech / developer communities? Why are women 50% of the workforce, but hold only 24% of the STEM or IT positions? Some beginnings of what to do about it! In her Day 2 Keynote at 17th Cloud Expo, Sandy Carter, IBM General Manager Cloud Ecosystem and Developers, and a Social Business Evangelist, wil...
