  • ADF - Now with Robots!

    - by Duncan Mills
    I mentioned this briefly in a tweet the other day, just before the full rush of OOW really kicked off, so I though it was worth re-visiting. Check out this video, and then read on: So why so interesting? Well - you probably guessed from the title, ADF is involved. Indeed this is as about as far from the traditional ADF data entry application as you can get. Instead of a database at the back-end there's basically a robot. That's right, this remarkable tape drive is controlled through an ADF using all your usual friends of ADF Faces, Controller and Binding (but no ADFBC for obvious reasons). ADF is used both on the touch screen you see on the front of the device in the video, and also for the remote management console which provides a visual representation of the slots and drives. The latter uses ADF's Active Data Framework to provide a real-time view of what's going on the rack. . What's even more interesting (for the techno-geeks) is the fact that all of this is running out of flash storage on a ridiculously small form factor with tiny processor - I probably shouldn't reveal the actual specs but take my word for it, don't complain about the capabilities of your laptop ever again! This is a project that I've been personally involved in and I'm pumped to see such a good result and,  I have to say, those hardware guys are great to work with (and have way better toys on their desks than we do). More info in the SL150 (should you feel the urge to own one) is here.

  • Two Hidden NetBeans Keyboard Shortcuts for Opening & Toggling between Views

    - by Geertjan
    The following are two really basic shortcuts for working with NetBeans editor windows that will be added to the Keyboard Shortcuts card for NetBeans IDE 7.2: Ctrl-Alt-PgUp/PgDown: Shortcuts for switching between editor types (e.g. Source, Design, History buttons). Switching between the editor types is a frequent operation sometimes, e.g., when using GUI builder, and while it can be done easily via mouse, or from View | Editors menu, it is very handy to know the shortcuts as well. Ctrl-PgUp/PgDown: Similarly, these are shortcuts for switching to next/previous opened document (tab). Note this is not like Ctrl-Tab that cycles in the last used order, but going through the tabs as they appear in the editor. Both shortcuts should fit into the "Opening and Toggling between Views" section. These are important to mention on the card because they are not visible anywhere else in the UI (as there are no menu items like "Go to next/previous editor type" or "Go to next/previous document"). Reported by Tomas Pavek from the NetBeans Team, here: http://netbeans.org/bugzilla/show_bug.cgi?id=213815

  • The Freemium-Premium Puzzle

    The more time I spend thinking about the value of information, the more I found that digitalizing information significantly changed the 'information markets', potentially in an irreversible manner. The graph at the bottom outlines my current view. The existing business models tend to be the same in the digital and analogue information world, i.e. revenue is derived from a combination of consumers' payments and advertisement. Even monetizing 'meta-information' such as search engines isn't new. Just think of the once popular 'Who'sWho'. What really changed is the price-value ratio. The curve is pushed down, closer to the axis. You pay less for the same, or often even get more for less. If you recall the capabilities I described in relevance of information you will see that there are many additional features available for digital content compared to analogue content. I think this is a good 'blue ocean strategy' by combining existing capabilities in a new way. (Kim W.C. & Mauborgne, R. (2005) Blue Ocean Strategies. Boston: Harvard Business School Publishing.). In addition the different channels of digital information distribution significantly change the value of information. I will touch on this in one of my next blogs. Right now, many information providers started to offer 'freemium' content through digital channels, hoping to get a premium for the 'full' content. No freemium seems to take them out of business, because they are apparently no longer visible in today's most relevant channels of information consumption. But, the more freemium is provided, the lower the premium gets; a truly puzzling situation. To make it worse, channel providers increasingly regard information as a value adding and differentiating activity. Maybe new types of exclusive, strategic alliances will solve the puzzle, introducing new types of 'gate-keepers', which - to me - somehow does not match the spirit of the WWW and the generation Y's perception of information consumption and exchange.

  • GeoTools Demo Embedded in an Application Framework via Maven

    - by Geertjan
    GeoTools 8.4 was very recently released, according to its active blog, and to celebrate here's a starting point for working with GeoTools on the NetBeans Platform: The sources of the above are below, as a Maven project, so this project can be used in any IDE or command line: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/tutorials/geospatial/geotools/MyGeospatialSystem Though quite dated, the GeoTools NetBeans Quick Start is very helpful, especially since it used Maven too, but not the NetBeans Platform, unlike the above sample. From the point of view of NetBeans Platform developers, the GeoTools JMapPane class is very useful, providing the integration point between GeoTools and the rest of the NetBeans Platform application. Being integrated into the NetBeans Platform means that a host of standard features are now available to the GeoTools features, e.g., print functionality, which only requires a runtime dependency on the NetBeans Print API, together with the "print.printable" client property put into constructor of the TopComponent: By the way, I've spent some time now and again being confused about the difference between GeoTools and GeoToolkit. Here's an interesting starting point to beginning to understand the differences and history between them. Soon I'd like to have an example similar for the above for GeoToolkit.

  • RequireJS: JavaScript for the Enterprise

    - by Geertjan
    I made a small introduction to RequireJS via some of the many cool new RequireJS features in NetBeans IDE. I believe RequireJS, and the modularity and encapsulation and loading solutions that it brings, provides the tools needed for creating large JavaScript applications, i.e., enterprise JavaScript applications. &amp;amp;lt;span id=&amp;amp;quot;XinhaEditingPostion&amp;amp;quot;&amp;amp;gt;&amp;amp;lt;/span&amp;amp;gt; (Sorry for the wobbly sound in the above.) An interesting comment by my colleague John Brock on the above: One other advantage that RequireJS brings, is called lazy loading of resources. In your first example, everyone one of those .js files is loaded when the first file is loaded in the browser. By using the require() call in your modules, your application will only load the javascript modules when they are actually needed. It makes for faster startup in large applications. You could show this by showing the libraries that are loaded in the Network Monitor window. So I did as suggested: Click the screenshot to enlarge it and notice how the Network Monitor is helpful in the context of RequireJS troubleshooting.

  • Eclipse and NetBeans replacing embedded IDEs (part 2 and part 3)

    - by Geertjan
    After part 1, in Embedded Insights, the series Eclipse and NetBeans replacing embedded IDEs by principal analyst Robert Cravotta continues below. Many embedded tool developers are choosing to migrate their embedded development toolset to an open source IDE platform for a number of reasons. Maintaining an up-to-date IDE with the latest ideas, innovations, and features requires continuous effort from the tool development team. In contrast to maintaining a proprietary IDE, adopting an open source IDE platform enables the tool developers to leverage the ideas and effort of the community and take advantage of advances in IDE features much sooner and without incurring the full risk of experimenting with new features in their own toolsets. Both the Eclipse and NetBeans platforms deliver regular releases that enable tool developers to more easily take advantage of the newest features in the platform architecture.  Read more of part 2 here, in an article published Thursday, May 17th, 2012. Both the NetBeans and Eclipse projects began as development environments and both evolved into platforms that support a wider array of software products. Both platforms have been actively supported and evolving open source projects that have competed and coexisted together for the past decade and this has led to a level a parity between the two platforms. From the perspective of a tool developer, applications are built the same way on either platform – the difference is in the specific terminology and tools. Read more of part 3 here, in an article published Tuesday, June 12th, 2012. And, as a bonus in this blog entry, here's how to get started creating an IDE on the NetBeans Platform:  http://netbeans.dzone.com/how-to-create-commercial-quality-ide

  • Eclipse Multitenancy. Now with a screencast.

    - by alexismp
    As a follow-up to the previous EclipseLink's mutitenancy blog post and the recent Eclipse Indigo release train and the recent GlassFish Podcast interview on EclipseLink, we now have a short screencast showing it all in action. You can also find it on the GlassFish YouTube Channel. The scenario is pretty simple with two simple and identical web applications deployed with different tenant identifiers via persistence.xml customization (just one of the means of identifying tenants with EclipseLink). Hopefully this'll help people understand what Java EE 7 multitenancy might look like.

  • Solaris 11 features: nscfg

    - by nospam(at)example.com (Joerg Moellenkamp)
    As you may have noticed many configuration tasks around name services have moved into the SMF in Solaris 11. However you don't have to use the svccfg command in order to configure them, you could still use the old files. However you can't just edit them, you have to import the data into the SMF repository. There are many reasons for this need but the ultimate one is in the start method. I will explain that later. In this article i want to explain, how nscfg can help you with with the naming service configuration of your system. Continue reading "Solaris 11 features: nscfg"

  • Reduced Tree View in NetBeans IDE 7.2

    - by Geertjan
    Right-click within the Projects window in NetBeans IDE 7.2 and from the "View Java Packages As" menu, you can now choose "Reduced Tree".I never really understood the difference between "Reduced Tree" and the already existing "Tree". But it makes sense when you see it. Here's Reduced Tree view: And here's Tree view, where you can see that the "actions" and "nodes" packages above each have their own top level package nodes, which takes up more space than the above: What's cool is that your selected package view is persisted across restarts of the IDE. To be complete, here's the List view, which is the third option you have in the "View Java Packages As" menu: Seems to me like the new Reduced Tree view combines the best of the Tree view with the best of the List view! Related issue: http://netbeans.org/bugzilla/show_bug.cgi?id=53192

  • Tell the CDI 2 Expert Group What You Think!

    - by reza_rahman
    Since it's introduction in Java EE 6, CDI has become a key API for the platform. CDI 1.1 was a relatively minor release included in Java EE 7 as was CDI 1.2 (to be included in GlassFish 4.0.1). We have much higher expectations from CDI 2 (projected to be included in Java EE 8) under the new leadership of Antoine Sabot-Durand. Much like we conducted the Java EE 8 survey to solidify future direction for the platform, CDI 2 is now undergoing the same effort. Towards this goal the CDI 2 leadership is now soliciting feedback on some very specific items via an open survey. Topics include the likes of Java SE bootstrap, asynchronous processing, modularity, EJB-style @Startup and @Asynchronous in CDI, configuration and CDI Lite. You can of course also provide free-form input on anything that's not on the survey. Take the survey now on the CDI specification site and help shape the future of CDI 2 and Java EE 8!

  • Poll: How long will you wait before using Solaris 11 on production systems?

    - by nospam(at)example.com (Joerg Moellenkamp)
    When Sun released Solaris 10, it was my first migration phase to a new Solaris major release while being part of Sun. At that time i heard a lot of comments between "Oh, we will install it on new systems on day 1" to "oh ... not that fast ... we will wait ... we are not that fast ... we will do it in a year". I would like to get some additional insight and so i set up the poll plugin for s9y to get the answer to the question "How long will you wait before using Solaris 11 on production system?". Thank you for your participation!

  • Servlet 3.1 Early Draft Now Available

    - by arungupta
    JSR 340 has released an Early Draft of the Servlet 3.1 specification. Other than the usual clarifications and javadoc updates, ProtocolHandler and WebConnection are new classes that encapsulates the protocol upgrade processing. This will typically be used for upgrading an HTTP connection to a WebSocket. Section 2.3.3.5 in the specification provide more details on it. Section 3.7 explain non-blocking request processing by the Web container. ReadListener and WriteListener are new interfaces that represents a call-back mechanism to read and write data without blocking. As with other Java EE 7 specifications, progress can be tracked at servlet-spec.java.net. The Expert Group discussions are archived and you can participate by sending an email to [email protected].

  • Jersey 2.0 Milestone 2 Now Available

    - by arungupta
    Jersey 2.0 milestone 2 is now available. It builds upon the first milestone and adds several new features such as server-side asynchronous processing, server-side content negotiation, improved JAX-RS parameter injection, and several others. The REST endpoints can be published on Java SE HTTP Server, Grizzly 2 HTTP container, and some basic Servlet-based deployments. It also provides HTTPURLConnection-based client API implementation. Read about these and more about what's new in Marek's detailed post. Of course this is also the future reference implementation for JAX-RS 2.0. Feel like trying it out? Simply go to Maven Central (of course none of this is production quality at this point). The latest JAX-RS Javadocs and Jersey 2.0 API docs are good starting points to explore. And provide them feedback at [email protected].

  • How to integrate Java ME SDK 3.2 with Eclipse

    - by SungmoonCho
    Here is also an instruction on how you can integrate Java ME SDK 3.2 with Eclipse. You need additional steps for Eclipse Juno, because it does automatically detect and download MTJ (Mobile Tools for Java) plugin. The following instruction is for Eclipse Indigo. 1. Download Java ME SDK and Eclipse plugins from here. 2. Install Java ME SDK 3. Launch Eclipse 4. Go to "Help" - "Install New Software" 5. Click "Archive", and choose the Eclipse Plugin zip file you downloaded. Name is something like "Java ME SDK Plugin" 6. Choose Java ME SDK Tools, and select "Next". 7. It will calculate requirements and dependencies. Simply follow the instruction. 8. You may also have to manually install the platform. Check out "Help" - "Preferences" - "Java ME" - "Device Management". If you do not see Java ME SDK 3.2 devices, click "Manual Install" on the right side, and specify the folder where Java ME SDK is installed. By default, it is installed at "C:\Java_ME_platform_SDK_3.2". 9. You're done. Now you can use the Java ME SDK plugins for Eclipse.

  • Installing Java ME SDK Plugin for NetBeans is now much easier!

    - by SungmoonCho
    The other day, I wrote about how to download and install Java ME SDK plugin for NetBeans. If you are using NetBeans 7.2.1 or later, you don't have to go through the whole process at all. It's now a matter of a few clicks, because all the plugins are now all in NetBeans update server. Here is a new way to install and integrate Java ME SDK plugins for NetBeans. 1. On NetBeans, go to "Tools"- "Plugins". 2. Click on "Available Plugins" tab. Locate "Java ME SDK Tools". 3. Check the tools you want to install, and click "Install" button at the bottom left corner. 4. NetBeans will restart, and that's it! Remember that different Java ME SDK requires different version of Plugins. If you are using Java ME SDK 3.0.5 or earlier, you must install Java ME SDK Tool version 2.0 (works with NetBeans 7.1.2 or earlier) If you are using Java ME SDK 3.2 or later, you must install Java ME SDK Tool version 3.0 (works with NetBeans 7.2 or later)
