• Mobile and Social for Retail

  - by David Dorf

  I've got two speaking gigs in the next few weeks, so I thought I'd preview both here. First I'll be at eTail West on February 24th to talk about mobile. I'll be previewing a new study of how shoppers are using mobile phones. Here's a sneak peek at one of the slides: It should be no surprise that as more consumers adopt smartphones, more are finding ways to use them to help with shopping. Sometimes that's to find a store, download a coupon, or do price comparisons. I'll also be discussing the NRF Mobile Blueprint, and will walk through an example of mobile impacting the in-store experience. Retailers need to look upon mobile as the method of bringing the digital assets of e-commerce into the aisles to enhance shopping. On March 9th I'll be at NRF Innovate co-presenting with Jon Kubo of Wet Seal on social strategies. Jon is a retail innovation rock-star and I always learn something new from every conversation with him. Below is a another slide preview: I cheated a little on the top 10 most popular retailer pages by not including Victoria's Secret Pink. VC is already represented, so I didn't include them a second time. The most interesting statistic I found was that the average user spends 55 minutes on Facebook a day. Wow! I also decided to use the old "Like" and "Fan" icons just because I like them better (pun intended). Wet Seal has been collecting interesting statistics on liked products, so I hope Jon will share lots (I'm on a roll). Hope to see you at both events.

• Az &eacute;rem m&aacute;sik oldala

  - by peter.nagy

  Az Exalogic kapcsán, ha már valaki hallott róla, akkor leginkább a teljesítmény ugrik be. Mint normálisan majdnem minden szerver megoldás új verziójánál. Nos ez nyilvánvalóan nincs másképp itt sem, amire büszkék is lehetünk. Ugyanakkor nagyon fontos tulajdonsága az Exalogicnak, hogy szinte azonnal hadrafogható. Ez persze már részben elérheto, mivel képesek vagyunk kész virtuális gépeket letölteni komplett telepítéssel. Persze ott még a vasra külön fel kell húzni a virtualizációs szoftvert. Na és itt jönnek a problémák. Bárki aki már látott, csinált, vagy végig nézte egy rendszerhez szükséges infrastruktúra felhúzását az tudja mirol beszélek. A telepítés, megfelelo verziók, szükséges patch-ek, hálózati eszközök bekötése. Aztán mindennek a konfigurálása. A legjobb esetben is napok, de inkább hetek kérdése mire üzemkész lenne. Az Exalogic esetében ez más, hiszen gyárilag összereszelték, a konfiguráció kialakítása gyakorlatilag néhány paraméter file és kész. De lássuk is, hogy mennyi ido onnan, hogy kibontottuk a dobozból. Mindössze egy nap. A hab a tortán pedig a full stack upgrade. Nem külön minden egyes komponenst. Firmware-tol a WebLogic szerverig.

• ADF version of "Modern" dialog windows

  - by Martin Deh

  It is no surprise with the popularity of the i-devices (iphone, ipad), that many of the iOS UI based LnF (look and feel) would start to inspire web designers to incorporate the same LnF into their web sites.  Take for example, a normal dialog popup.  In the iOS world, the LnF becomes a bit more elegant by add just a simple element as a "floating" close button: In this blog post, I will describe how this can be accomplished using OOTB ADF components and CSS3 style elements. There are two ways that this can be achieved.  The easiest way is to simply replace the default image, which looks like this, and adjust the af|panelWindow:close-icon-style skin selector.   Using this simple technique, you can come up with this: The CSS code to produce this effect is pretty straight forward: af|panelWindow.test::close-icon-style{    background-image: url("../popClose.gif");    line-height: 10px;    position: absolute;    right: -10px;    top: -10px;    height:38px;    width:38px;    outline:none; } You can see from the CSS, the position of the region, which holds the image, is relocated based on the position based attributes.  Also, the addition of the "outline" attribute removes the border that is visible in Chrome and IE.  The second example, is based on not having an image to produce the close button.  Like the previous sample, I will use the OOTB panelWindow.  However, this time I will use a OOTB commandButton to replace the image.  The construct of the components looks like this: The commandButton is positioned first in the hierarchy making the re-positioning easier.  The commandButton will also need a style class assigned to it (i.e. closeButton), which will allow for the positioning and the over-riding of the default skin attributes of a default button.  In addition, the closeIconVisible property is set to false, since the default icon is no longer needed.  Once this is done, the rest is in the CSS.  Here is the sample that I created that was used for an actual customer POC: The CSS code for the button: af|commandButton.closeButton, af|commandButton.closeButton af|commandButton:text-only{     line-height: 10px;     position: absolute;     right: -10px;     top: -10px;     -webkit-border-radius: 70px;     -moz-border-radius: 70px;     -ms-border-radius: 70px;     border-radius: 70px;     background-image:none;     border:#828c95 1px solid;     background-color:black;     font-weight: bold;     text-align: center;     text-decoration: none;     color:white;     height:30px;     width:30px;     outline:none; } The CSS uses the border radius to create the round effect on the button (in IE 8, since border-radius is not supported, this will only work with some added code). Also, I add the box-shadow attribute to the panelWindow style class to give it a nice shadowing effect.

• JAX-RS 2.0 Early Draft - Third Edition Available

  - by arungupta

  JAX-RS 2.0 Early Draft Third Edition is now available. This updated draft include new samples explaining the features and clarifications in content-negotiation, discovery of providers, client-side API, filters and entity interceptors and several other sections. Provide feedback to users@jax-rs-spec. Jersey 2.0, the Reference Implementation of JAX-RS 2.0, released their fourth milestone a few days ago as well. Several features have already been implemented there. Note, this is an early development preview and several parts of the API and implementation are still evolving. 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] or @gf_jersey.

• What Extends JComponent?

  - by Geertjan

  Let NetBeans IDE tell you what extends JComponent: Thanks to Damian from Gdansk in Poland who left a comment in this blog yesterday that explains how to achieve the above: "Let's say you would like to find all implementations of TreeModel interface. I found today an answer: r-click on class/interface -> chose Navigate->Inspect Hierarchy->select second filter at the bottom of opened window or press Alt+Shift+F12 and then Alt+B." In the list above, double-click an item to open it in the NetBeans Java editor. Handy tip, dziekuje bardzo, Damian.

• Architecture: Bringing Value to the Table

  - by Bob Rhubart

  A recent TechTarget article features an interview with Business Architecture expert William Ulrich (Take a business-driven approach to application modernization ). In that article Ulrich offers this advice: "Moving from one technical architecture might be perfectly viable on a project by project basis, but when you're looking at the big picture and you want to really understand how to drive business value so that the business is pushing money into IT instead of IT pulling money back, you have to understand the business architecture. When we do that we're going to really be able to start bringing value to the table." In many respects that big picture view is what software architecture is all about. As an architect, your technical skills must be top-notch. But if you don't apply that technical knowledge within the larger context of moving the business forward, what are you accomplishing? If you're interested in more insight from William Ulrich, you can listen to the ArchBeat Podcast interview he did last year, in which he and co-author Neal McWhorter talked about their book, Business Architecture: The Art and Practice of Business Transformation.

• jtreg update, December 2012

  - by jjg

  There is a new version of jtreg available. The primary new feature is support for tests that have been written for use with TestNG, the popular open source testing framework. TestNG is supported by a variety of tools and plugins, which means that it is now possible to develop tests for OpenJDK using those tools, while still retaining the ability to have the tests be part of the OpenJDK test suite, and run with a single test harness, jtreg. jtreg can be downloaded from the OpenJDK jtreg page: http://openjdk.java.net/jtreg. TestNG support jtreg supports both single TestNG tests, which can be freely intermixed with other types of jtreg tests, and groups of TestNG tests. A single TestNG test class can be compiled and run by providing a test description using the new action tag: @run testng classname The test will be executed by using org.testng.TestNG. No main method is required. A group of TestNG tests organized in a standard package hierarchy can also be compiled and run by jtreg. Any such group must be identified by specifying the root directory of the package hierarchy. You can either do this in the top level TEST.ROOT file, or in a TEST.properties file in any subdirectory enclosing the group of tests. In either case, add a line to the file of the form: TestNG.dirs = dir ... Directories beginning with '/' are evaluated relative to the root directory of the test suite; otherwise they are evaluated relative to the directory containing the declaring file. In particular, note that you can simply use "TestNG.dirs = ." in a TEST.properties file in the root directory of the test group's package hierarchy. No additional test descriptions are necessary, but test descriptions containing information tags, such as @bug, @summary, etc are permitted. All the Java source files in the group will be compiled if necessary, before any of the tests in the group are run. The selected tests within the group will be run, one at a time, using org.testng.TestNG. Library classes The specification for the @library tag has been extended so that any paths beginning with '/' will be evaluated relative to the root directory of the test suite. In addition, some bugs have been fixed that prevented sharing the compiled versions of library classes between tests in different directories. Note: This has uncovered some issues in tests that use a combination of @build and @library tags, such that some tests may fail unexpectedly with ClassNotFoundException. The workaround for now is to ensure that library classes are listed before the test classes in any @build tags. To specify one or more library directories for a group of TestNG tests, add a line of the following form to the TEST.properties file in the root directory of the group's package hierarchy: lib.dirs = dir ... As before, directories beginning with '/' are evaluated relative to the root directory of the test suite; otherwise they are evaluated relative to the directory containing the declaring file. The libraries will be available to all classes in the group; you cannot specify different libraries for different tests within the group. Coming soon ... From this point on, jtreg development will be using the new jtreg repository in the OpenJDK code-tools project. There is a new email alias jtreg-dev at openjdk.java.net for discussions about jtreg development. The existing alias jtreg-use at openjdk.java.net will continue to be available for questions about using jtreg. For more information ... An updated version of the jtreg Tag Language Specification is being prepared, and will be made available when it is ready. In the meantime, you can find more information about the support for TestNG by executing the following command: $ jtreg -onlinehelp TestNG For more information on TestNG itself, visit testng.org.

• Less Can Be More In E-Commerce

  - by Michael Hylton

  Today’s consumers are inundated with product choices and vendors. Visit your favorite electronics retailer and see the vast assortment of flat panel televisions. Or the variety of detergents at the supermarket. All of this can be daunting for the average consumer who is looking for the products and services that interest them.  In a study titled “Choice is Demotivating: Can One Desire Too Much of a Good Thing”, the author, Sheena Iyengar found that participants actually reported greater subsequent satisfaction with their selections and wrote better essays when their original set of options had been limited. The same can be said for e-commerce and your website. Being able to quickly convert shoppers into buyers with effective merchandising is what makes leading businesses successful. You want to engage each individual visitor with the most-relevant content to drive higher conversions and order values while decreasing abandonment, but predicting what will resonate with each customer is difficult. In a world of choices, online merchandizing tools can help personalize, streamline, and refine what your customers view when they browse your online catalog. The key to being effective is to align your products and content as closely as possible with the customer’s needs. The goal on the home page is to promote your brand and push visitors farther into the site. The home page is often the starting point for repeat customers as well as for new visitors hoping to address their current product needs. As the customer selects different filters and narrows the choices, valuable information is being provided to the retailer about the customer’s current need—regardless of previous search behavior or what other customers with a similar demographic profile have purchased. Together with search pages, category browse pages are among the primary options available to customers as a means of finding products on your site. Once a customer reaches the product detail page, it is clear what that person desires, regardless of the segment the customer falls into. However, don’t disregard campaign-based promotions completely. A campaign targeted to all customers but featuring rule-driven promotions tied to the product can be effective. Click here to learn more about merchandizing techniques so what your customer sees if half full and not half empty.

• Upcoming Enhancements in AngularJS Integration in NetBeans IDE

  - by Geertjan

  New bleeding edge enhancements in AngularJS support in NetBeans IDE enable many more controllers to be found than in NetBeans IDE 7.4. The next version of NetBeans IDE parses all JavaScript files and checks for defined AngularJS controllers, such as the below: All recognized AngularJS controllers are offered in code completion, as shown below. In other words, code completion works better in finding AngularJS controllers. Another improvement is in the "Go To Declaration" feature. When you click Ctrl+Mouse over the name of a controller inside an NG-controller directive, you will be navigated to the related controller declaration. More accurate results can be shown in code completion mainly because there are changes in the generation of JavaScript virtual sources in an AngularJS page.

• Jersey 1.8 is released

  - by Jakub Podlesak

  On the last Friday, we have released the 1.8 version of Jersey, the open source, production quality, reference implementation of JAX-RS. The JAX-RS 1.1 specification is available at the JCP web site and also available in non-normative HTML here. For an overview of JAX-RS features read the Jersey user guide. To get started with Jersey read the getting started section of that guide. To understand more about what Jersey depends on read the dependencies section of that guide. See change log here. This, 1.8, version of Jersey is going to be integrated into GlassFish 3.1.1 and contains bug fixes mainly. The most important fix from this perspective is included in the JAX-RS/EJB integration layer. It is now possible to implement JAX-RS resources as EJB Session beans, which implement local and/or remote interfaces. This functionality was broken in previous releases. Another great addition should come into the client space, where Pavel has already done some preparation in the client API (including some breaking changes there) for the non-blocking asynchronous client feature. The implementation is already part of the experimental Jersey space and should be included as part of the stable Jersey bits in some of the coming releases. For feedback send email to: [email protected] (archived here) or log bugs/features here.

• Geek Bike Ride JavaOne 2012

  - by Tori Wieldt

  "Geek Bike Ride?" the clerk at the bike rental shop asked. "Are you guys all from the same company?" "We aren't even from the same country!" we answered. "I'm from Russia." "We're from Germany."  "I'm from Belgium." "I'm from Palo Alto." "I'm from Japan."  "We're from Brazil." "We're from Brazil." "I'm from Sweden." "Coooool" was all she could say. She was right. The Geek Bike Ride was cooool. We had 39 bike riders and one skater show up Saturday for a great route from San Francisco's Fisherman's Wharf, across the Golden Gate bridge, to Saulsalito, and back to the city by ferry. Duke Bike jerseys, sponsored by OTN, were given out. To make sure Java developers got them, each person had to answer a Java question to get a jersey. The questions were really hard, like "Who is the Father of Java?" "What's the biggest Java conference in San Francisco?" The best was when the question was "Name one of Duke's Choice Award winner from this year," and Régina ten Bruggencate answered answered "Me!"  It was foggy throughout the day, with the sun poking out occasionally. The fog was thickest on the bridge, more that one rider commented that we were "in the cloud." It was a great day to meet new friends, and have a chat with old friends. We all had fun, though some of us may more a little more slowly during JavaOne. Ride on!  Photos by permission by Arun Gupta and Yoshio Terada. Thanks, guys!

  Here's a game that started on on the iDrone, then Anphoid, and now finally on Java ME tech-enabled mobile phones (thank goodness!). See: Majesty: Fantasy Kingdom Here's a quote: When you become the head of the country all the responsibility for the land's prosperity rests on your royal shoulders. You will have to fight various enemies and monsters, explore new territories, manage economic and scientific developments and solve a heap of unusual and unexpected tasks. For example, what will you do when all the gold in the kingdom transforms into cookies? Sounds like the same as becoming President of the U.S... except for the gold turning into cookies part... and the part about dragons. But, everything else is the same. Hinkmond

• RPi and Java Embedded GPIO: Big Data and Java Technology

  - by hinkmond

  Java Embedded and Big Data go hand-in-hand, especially as demonstrated by prototyping on a Raspberry Pi to show how well the Java Embedded platform can perform on a small embedded device which then becomes the proof-of-concept for industrial controllers, medical equipment, networking gear or any type of sensor-connected device generating large amounts of data. The key is a fast and reliable way to access that data using Java technology. In the previous blog posts you've seen the integration of a static electricity sensor and the Raspberry Pi through the GPIO port, then accessing that data through Java Embedded code. It's important to point out how this works and why it works well with Java code. First, the version of Linux (Debian Wheezy/Raspian) that is found on the RPi has a very convenient way to access the GPIO ports through the use of Linux OS managed file handles. This is key in avoiding terrible and complex coding using register manipulation in C code, or having to program in a less elegant and clumsy procedural scripting language such as python. Instead, using Java Embedded, allows a fast way to access those GPIO ports through those same Linux file handles. Java already has a very easy to program way to access file handles with a high degree of performance that matches direct access of those file handles with the Linux OS. Using the Java API java.io.FileWriter lets us open the same file handles that the Linux OS has for accessing the GPIO ports. Then, by first resetting the ports using the unexport and export file handles, we can initialize them for easy use in a Java app. // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); ... // Reset the port unexportFile.write(gpioChannel); unexportFile.flush(); // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); Then, another set of file handles can be used by the Java app to control the direction of the GPIO port by writing either "in" or "out" to the direction file handle. // Open file handle to input/output direction control of port FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for input directionFile.write("in"); // Or, use "out" for output directionFile.flush(); And, finally, a RandomAccessFile handle can be used with a high degree of performance on par with native C code (only milliseconds to read in data and write out data) with low overhead (unlike python) to manipulate the data going in and out on the GPIO port, while the object-oriented nature of Java programming allows for an easy way to construct complex analytic software around that data access functionality to the external world. RandomAccessFile[] raf = new RandomAccessFile[GpioChannels.length]; ... // Reset file seek pointer to read latest value of GPIO port raf[channum].seek(0); raf[channum].read(inBytes); inLine = new String(inBytes); It's Big Data from sensors and industrial/medical/networking equipment meeting complex analytical software on a small constraint device (like a Linux/ARM RPi) where Java Embedded allows you to shine as an Embedded Device Software Designer.
