  • SOA Governance Starts with People and Processes

    - by Jyothi Swaroop
    While we all agree that SOA Governance is about People, Processes and Technology. Some experts are of the opinion that SOA Governance begins with People and Processes but needs to be empowered with technology to achieve the best results. Here's an interesting piece from David Linthicum on eBizq: In the world of SOA, the concept of SOA governance is getting a lot of attention. However, how SOA governance is defined and implemented really depends on the SOA governance vendor who just left the building within most enterprises. Indeed, confusion is a huge issue when considering SOA governance, and the core issues are more about the fundamentals of people and processes, and not about the technology. SOA governance is a concept used for activities related to exercising control over services in an SOA, including tracking the services, monitoring the service, and controlling changes made to the services, simple put. The trouble comes in when SOA governance vendors attempt to define SOA governance around their technology, all with different approaches to SOA governance. Thus, it's important that those building SOAs within the enterprise take a step back and understand what really need to support the concept of SOA governance. The value of SOA governance is pretty simple. Since services make up the foundation of an SOA, and are at their essence the behavior and information from existing systems externalized, it's critical to make sure that those accessing, creating, and changing services do so using a well controlled and orderly mechanism. Those of you, who already have governance in place, typically around enterprise architecture efforts, will be happy to know that SOA governance does not replace those processes, but becomes a mechanism within the larger enterprise governance concept. People and processes are first thing on the list to get under control before you begin to toss technology at this problem. This means establishing an understanding of SOA governance within the team members, including why it's important, who's involved, and the core processes that are to be follow to make SOA governance work. Indeed, when creating the core SOA governance strategy should really be independent of the technology. The technology will change over the years, but the core processes and discipline should be relatively durable over time.

  • ?Portal Content Personalization

    - by john.brunswick
    To make the most effective use of a portal and content management platform, personalization is a critical component of delivering the most value to end users. Regardless of what type of constituents you may be serving, content relevance is critical to support business goals like self-service, communication within a geographically distributed organization, lead generation and customer loyalty effectively. This especially holds true when serving external parties, as they generally have a lower threshold for digging through your site to locate a particular item of interest and are apt to leave or dial a helpdesk if their efforts cannot locate the relevant information. Optimal delivery of content can be achieved through a variety of methods, but it is generally a blend of security and filtering via meta data that can drive the most return with the least amount of upfront effort and ongoing upkeep. In a portal environment various platform components have their strong suits and by combining the capabilities of enterprise portal and content platforms much of the groundwork for personalization can be achieved in a configuration-based manner. In our discussion we will cover terminology and concepts, example scenarios and technical implementation strategies to help showcase how personalization of content can be achieved within a portal from a technical and strategic standpoint. Read on to better understand the chart below and the components at our disposal to personalize content delivery. Read on... click here to view a full size chart

  • View Clipboard & Copy To Clipboard from NetBeans IDE

    - by Geertjan
    Thanks to this code, I can press Ctrl-Alt-V in NetBeans IDE and then view whatever is in the clipboard: import java.awt.Toolkit; import java.awt.datatransfer.DataFlavor; import java.awt.datatransfer.Transferable; import java.awt.datatransfer.UnsupportedFlavorException; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.IOException; import javax.swing.JOptionPane; import org.openide.awt.ActionRegistration; import org.openide.awt.ActionReference; import org.openide.awt.ActionReferences; import org.openide.awt.ActionID; import org.openide.util.NbBundle.Messages; @ActionID( category = "Tools", id = "org.demo.ShowClipboardAction") @ActionRegistration( displayName = "#CTL_ShowClipboardAction") @ActionReferences({ @ActionReference(path = "Menu/Tools", position = 5), @ActionReference(path = "Shortcuts", name = "DA-V") }) @Messages("CTL_ShowClipboardAction=Show Clipboard") public final class ShowClipboardAction implements ActionListener { @Override public void actionPerformed(ActionEvent e) { JOptionPane.showMessageDialog(null, getClipboard(), "Clipboard Content", 1); } public String getClipboard() { String text = null; Transferable t = Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null); try { if (t != null && t.isDataFlavorSupported(DataFlavor.stringFlavor)) { text = (String) t.getTransferData(DataFlavor.stringFlavor); } } catch (UnsupportedFlavorException e) { } catch (IOException e) { } return text; } } And now I can also press Ctrl-Alt-C, which copies the path to the current file to the clipboard: import java.awt.Toolkit; import java.awt.datatransfer.Clipboard; import java.awt.datatransfer.StringSelection; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import org.openide.awt.ActionID; import org.openide.awt.ActionReference; import org.openide.awt.ActionReferences; import org.openide.awt.ActionRegistration; import org.openide.awt.StatusDisplayer; import org.openide.loaders.DataObject; import org.openide.util.NbBundle.Messages; @ActionID( category = "Tools", id = "org.demo.CopyPathToClipboard") @ActionRegistration( displayName = "#CTL_CopyPathToClipboard") @ActionReferences({ @ActionReference(path = "Menu/Tools", position = 0), @ActionReference(path = "Editors/Popup", position = 10), @ActionReference(path = "Shortcuts", name = "DA-C") }) @Messages("CTL_CopyPathToClipboard=Copy Path to Clipboard") public final class CopyPathToClipboardAction implements ActionListener { private final DataObject context; public CopyPathToClipboardAction(DataObject context) { this.context = context; } @Override public void actionPerformed(ActionEvent e) { String path = context.getPrimaryFile().getPath(); StatusDisplayer.getDefault().setStatusText(path); StringSelection ss = new StringSelection(path); Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard(); clipboard.setContents(ss, null); } }

  • Defining Social Media Terms

    - by David Dorf
    As I talk about social in the context of retail, I sometimes get tripped up on different terms. I know what I mean, but the audience may have something else in mind. So I decided to see if I could find some well accepted definitions for common terms. While there are definitions on the Internet, I'm not sure they are well accepted. After reviewing several, here's what I came up with: Social Network: a structure of individuals and groups connected together by commonality. That seems pretty straightforward. A group of friends, co-workers, music fans, etc. The key here is that they have something in common that connects them. Social Media: Internet channels that support the collaborative publishing of information by and for social networks. The key here is to differentiate between traditional one-way media, and conversational social media. When its social its two-way, allowing both the publishing and consuming of information. Examples are blogs, wikis, Twitter, Facebook, etc. Social Marketing: the use of social media for marketing, public relations, and customer service. Wikipedia actually includes "selling" here but I think that's separate from marketing, as you'll see further down below. Most people look at social media as entertainment, but the marketing angle adds business value. This is where retailers discover and engage customers to build a relationship. Social Merchandising: the integration of social media and product discovery. Whereas marketing is focused more on brand image, customer engagement, and promotions, merchandising is more directly trying to convert browsers into purchases. This includes deciding what customers want, often by asking the social network, and deciding how to position products to the social network. Social Selling: the incorporation of e-commerce into social media. While on a social media site, social selling enables the purchasing of goods/services in the user's context, without leaving the social media channel. If a user clicks on an advertisement and is taken to an e-commerce site, then that's really just web advertising and not social selling. Well, do these terms and definitions make sense? Let me know what you think.

  • What will be important in Training in 2011?

    - by anders.northeved
      Now that we have started a new year I would like to give you a list of topics I think we will be discussing in training and learning in 2011. Some of the areas we have discussed earlier will still be just as important in 2011: Time-to-knowledge Still one of the most important issues for the training department. Internal content production Related to time-to-knowledge. How do we convert internal knowledge to a format that can be used for teaching others? LMS integration How do we get our existing LMS fully integrated with our other ERP modules like HCM, Order Management, Finance, Payroll etc. Some areas have been discussed before, but we’ll focus more on these in 2011: Combining internal and external training A majority of training departments use a combination of external and internal training. Having the right mix is vital for the quality and efficiency for most training organizations. Certification More rules and regulations means managing all employee certifications is more important than ever. Evolving trends in 2011: Social Learning We have been talking about this for a long time, but 2011 will be the year where we will start using it for real (OK, I also said so last year – but this year I’m right…). Real-life use of SCORM 2004 Again a topic we have talked about for a long time, but we are now actually starting to use it to give learners a better e-learning experience. How do we engage and delight the learner? e-learning makes economical sense, it can be easy to understand, it is convenient – but how do we make it more engaging and delight our learners? How to include more types of training in LMS One of the main focus area of 2011 will be how to manage and measure mobile learning , on-the-job-training and other forms of training in the LMS. Mobile Learning With the ever growing use of smart phones mobile learning will be THE hot topic of 2011 in the training world. New topics we will begin discussing in 2011: What is beyond web 2.0 and social learning? - could it be content verification and personal accreditation? Why gaming will not be the silver bullet for all types of e-learning Many people believe gaming can be used for any kind of training, but the creation is too expensive and time consuming for most applications. Do you agree with these predictions? What are your own predictions? Let me see your comments! (photo: © Marti, photoxpress.com)

  • Want to Run OS Commands From WLST?

    - by Bala Kothandaraman
    If you spend a lot of time with WLST in the interactive mode, I am sure you have opened another command prompt/shell to check something at the OS file system level. If you wonder whether can execute an OS command from within WLST prompt, the answer is "Yes". This is very convenient similar to how you can execute OS commands from within "Vi" editor. In fact this feature is not from WLST but from underlying Jython. There is "os" module in Jython that provides a unified interface to a number of operating system functions. There is "system" function in the "os" module that can take a OS command as a string input and returns either "0" or "1" depends on whether the command was successful or failed. So this feature can also be used with scripting mode where the return code can be verified for further processing in the script. For eg. os.system(r'dir c:\bea') can list the contents of the bea folder under c drive. Notice the use of the preceding 'r' for escaping the entire string.

  • GlassFish Clustering with DCOM on Windows

    - by ByronNevins
    DCOM - Distributed COM, a Microsoft protocol for communicating with Windows machines. Why use DCOM? In GlassFish 3.1 SSH is used as the standard way to run commands on remote nodes for clustering.  It is very difficult for users to get SSH configured properly on Windows.  SSH does not come with Windows so we have to depend on third party tools.  And then the user is forced to install and configure these tools -- which can be tricky. DCOM is available on all supported platforms.  It is built-in to Windows. The idea is to use DCOM to communicate with remote Windows nodes.  This has the huge advantage that the user has to do minimal, if any, configuration on the Windows nodes. Implementation HighlightsTwo open Source Libraries have been added to GlassFish: Jcifs – a SAMBA implementation in Java J-interop – A Java implementation for making DCOM calls to remote Windows computers.   Note that any supported platform can use DCOM to work with Windows nodes -- not just Windows.E.g. you can have a Linux DAS work with Windows remote instances.All existing SSH commands now have a corresponding DCOM command – except for setup-ssh which isn’t needed for DCOM.  validate-dcom is an all new command. New DCOM Commands create-node-dcom delete-node-dcom install-node-dcom list-nodes-dcom ping-node-dcom uninstall-node-dcom update-node-dcom validate-dcom setup-local-dcom (This is only available via Update Center for GlassFish 3.1.2) These commands are in-place in the trunk (4.0).  And in the branch (3.1.2) Windows Configuration Challenges There are an infinite number of possible configurations of Windows if you look at it as a combination of main release, service-pack, special drivers, software, configuration etc.  Later versions of Windows err on the side of tightening security be default.  This means that the Windows host may need to have configuration changes made.These configuration changes mostly need to be made by the user.  setup-local-dcom will assist you in making required changes to the Windows Registry.  See the reference blogs for details. The validate-dcom Command validate-dcom is a crucial command.  It should be run before any other commands.  If it does not run successfully then there is no point in running other commands.The validate-dcom command must be used from a DAS machine to test a different Windows machine.  If  validate-dcom runs successfully you can be confident that all the DCOM commands will work.  Conversely, the opposite is also true:  If validate-dcom fails, then no DCOM commands will work. What validate-dcom does Verify that the remote host is not the local machine. Resolves the remote host name Checks that the remote DCOM port is being listened on (135, 139) Checks that the remote host’s File Sharing is enabled (port 445) It copies a file (a script) to the remote host to verify that SAMBA is working and authorization is correct It runs a script that it copied on-the-fly to the remote host. Tips and Tricks The bread and butter commands that use DCOM are existing commands like create-instance, start-instance etc.   All of the commands that have dcom in their name are for dealing with the actual nodes. The way the software works is to call asadmin.bat on the remote machine and run a command.  This means that you can track these commands easily on the remote machine with the usual tools.  E.g. using AS_LOGFILE, looking at log files, etc.  It’s easy to attach a debugger to the remote asadmin process, “just in time”, if necessary. How to debug the remote commands:Edit the asadmin.bat file that is in the glassfish/bin folder.  Use glassfish/lib/nadmin.bat in GlassFish 4.0+Add these options to the java call:-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1234  Now if you run, say start-instance on DAS, you can attach your debugger, at your leisure, to the remote machines port 1234.  It will be running start-local-instance and patiently waiting for you to attach.

  • ASX: Just Another Stock Market Operator

    - by Theresa Hickman
    I try to stay informed with what's happening in global financial markets since we all know they are all interconnected. Last week, on Mar. 11 2010, Australia's Senate passed a law that reduced Australia's stock market's role to just a stock market operator. Before this, ASX (Australian Stock Exchange) acted as both its own regulator and operator (supervising trade actvities and handling the trades) of Australia's stock market. Many viewed this as a conflict of interest. So now, the Australian Securities & Investments Commision (ASIC) will act as regulator and ASX will simply be a stock market operator to ensure the continued integrity of financial markets. I believe what this is doing is laying the groundwork to have more than one stock exchange in Australia. I woudn't be surpised if Nasdaq makes a play. As you may or may not know, Nasdaq had been trying for years to take over control of the London Stock Exchange (LSE), which LSE had rejected because it thinks it is worth more than what Nasdaq is willing to pay. Nasdaq or even NYSE may want a piece of Asia/Pacific because nowadays most of the IPOs are coming from foreign companies outside the US. I didn't know this, but apparently many Asia/Pacific stock exchanges have a monopoly where they act as both regulator and operator. I'll be curious to see what happens after the ASIC meet and decide how to regulate Australia's stock exchange to see how many suitors come running towards Australia's financial market.

  • O modelo diamante para gerenciamento de projetos

    - by fernando.galdino
    Este ano comecei a fazer o mestrado em Gestão de Projetos. No decorrer deste período estudamos vários assuntos envolvendo abordagens de gerenciamento de projetos. Uma dessas abordagens é o Modelo Diamante. Elaborada por Aaron Shenhar e Dov Dvir, e explicada em detalhes no livro “Reinventando Gerenciamento de Projetos”, trata-se de uma estrutura que permite avaliar um projeto, e com base nos resultados, permite que o gerente de projetos possa usar uma abordagem como o descrito no PMBOK (PMI), de modo a aproveitar da melhor forma possível, as boas práticas listadas. A apresentação abaixo foi realizada por mim, numa das aulas do curso. Explica com alguns detalhes, e ao mesmo tempo fornece uma visão geral, sobre o modelo NTCP, que é uma estrutura que permite avaliar um projeto em termos de novidade, incerteza tecnológica, complexidade e ritmo.   Modelo NTCP View more presentations from Fernando Galdino.

  • Sony Ericsson txt: workhorse feature phone with Java ME tech

    - by hinkmond
    Just like your basic Quarter Horse, the new Sony Ericsson txt feature phone might not be as fancy as a "thoroughbred" smartphone, but it can sure get the job done with Java ME technology. See: Sony Ericsson txt w/Java ME Here's a quote: ...comes with the usual features such as a web browser, email client and music player and FM radio, plus support for social networking applications and a YouTube client. You can download and install additional Java applications... Sometimes the simple workhorse feature phone (with Java ME) is much better to go with than the idiosyncratic thoroughbred smartphone.

  • Integrating JavaFX Scene Builder in the IDEs

    - by Jerome Cambon
    I experienced recently using Scene Builder from Netbeans, Eclipse and IntelliJ IDEA. As you may know, Scene Builder is a standalone tool, that can be used independently of any IDE. But it can be very convenient to use it with your favorite IDE, for instance start it by double-clicking on an FXML file, or run samples delivered with Scene Builder.  I'm sharing here with you few tweaks that I had to do for a better integration. Scene Builder 1.1 Developer Preview should be installed before doing the tweaks. The steps below have been done on Windows 7. It should be very similar on both Mac OS and Linux. Please tell me if you find any issue on one of these 2 platforms. Netbeans 7.3 Netbeans 7.3 can be downloaded from here. Creating a New FXML project Part of the JavaFx projects, Netbeans allows to create a 'JavaFX FXML Application', that creates a JavaFx project based on FXML description. The FXML file will be editable with Scene Builder. Starting Scene Builder from Netbeans If SceneBuilder 1.1 is installed, Netbeans will discover it automatically.In case of issue, one can open the Options panel, Java section, JavaFx tab. Scene Builder home should appear here. You can then either Open the FXML file with Scene Builder, or edit it with the Netbeans FXML editor : When 'Open' is selected, Scene Builder appears on top of the Netbeans window : When 'Edit' is selected, the FXML is opened in the Netbeans FXML editor, which support syntax highlighting and completion : Using Scene Builder Samples Scene Builder provides Netbeans projects, that can be opened/run directly : Eclipse 4.2.1 + e(fx)clipse 0.1.1 JavaFX integration in Eclipse has been done with the e(fx)clipse plugin. A distribution bundle containing Eclipse and e(fx)clipse is provided here. Creating New FXML project All the JavaFX-related projects can be found in 'Other' section : First create a new JavaFX project: Enter the project name (Test here). JavaFX delivery will be found in the JRE. Then, create a 'New FXML Document': Enter the FXML file name (Sample here). You may also want to choose the FXML document root element (AnchorPane by default). Dynamic root is for advanced users which want to manage custom types. Starting Scene Builder from Eclipse Once created, you can then either Open the FXML file with Scene Builder, or Open it in the Eclipse FXML editor : Using Scene Builder Samples from Eclipse To use Scene Builder samples, first create a new JavaFX Project (from 'Other' section): Then, on the next panel, 'Link additionnal source': … and select the source directory of a Scene Builder example : HelloWorld here (the parent directory of the java package should be selected).Then, choose a 'Folder name' for your sample: You can now run the Scene Builder example by right-clicking the Main.java source file: IntelliJ IDEA 11.1.3 IntelliJ IDEA Community Edition can be downloaded from here. IntelliJ IDEA has no specific JavaFX integration. Creating New IntelliJ project from existing source Since IntelliJ has no JavaFX project knowledge, we are using the Scene Builder samples as a starting point. We are going to create a new Java project from the HelloWorld sample: Then, click twice on 'Next' (nothing to change), then 'Finish'. The 'HelloWorld' project is created. Starting Scene Builder from IntelliJ We need to tell the IDE that FXML files are opened with an external application. Then, the OS file association will be used. To do this, open the File->Settings panel. Then, select 'File Types' and 'Files opened in associated applications'. And add a new wildcard : '*.fxml' : Now, from the HelloWorld project, you can double-click on HelloWorld.fxml : Scene Builder window appears on top of the IntelliJ window : Using Scene Builder Samples from IntelliJ We need to tell IntelliJ that the fxml files must be copied in the build directory.To do that, from the HelloWorld directory, open the 'idea' section, and edit the 'compiler.xml' file. We need to add an '*.fxml' entry: Then, you can run the sample from HelloWorld project, by right-clicking the Main class:

  • Using the af:poll to refresh parts of the page periodically

    - by shay.shmeltzer
    Just a quick sample of using the af:poll components. A component that enables you to do things in a periodic fashion. For example check if something has changed on the server and update the UI. A more "modern" approach is to actually use push instead of pull, and ADF Faces will allow you to do that with ADS (here, and here). But the poll still has its place. It's quite useful for dashboard type of applications where you want periodic updates of the graphs shown on the page. As you can see it's quite simple to use the tag. I also show my lazy approach to invoking declarative operations on a data control from a backing bean without manually writing code.

  • SQL Developer: Describe versus Ctrl+Click to Open Database Objects

    - by thatjeffsmith
    In yesterday’s post I talked about you could use SQL Developer’s Describe (SHIFT+F4) to open a PL/SQL Package at your cursor. You might get an error if you try to describe this… If you actually try to describe the package as you see it in the above screenshot, you’ll get an error: Doh! I neglected to say in yesterday’s post that I was highlighting the package name before I hit SHIFT+F4. This works just fine, but it will work even better in our next release as we’ve fixed this issue. Until then, you can also try the Ctrl+Hover with your mouse. For PL/SQL calls you can open the source immediately based on what you’re hovering over with your mouse cursor. You could try this with “dbms_output.put_line(” too Ctrl+Click, It’s not just for PL/SQL If you don’t like the floating describe windows you get when you do a SHIFT+F4 on a database object, the ctrl+click will work too. Instead of opening a normal ‘hover’ panel, you’ll be taken directly to the object editor for that table, view, etc. Go ahead and try it right now. Paste this into your worksheet, then ctrl+click with your mouse over the table name: select * from scott.emp And now you know, the rest of the story.

  • RPi and Java Embedded GPIO: Writing Java code to blink LED

    - by hinkmond
    So, you've followed the previous steps to install Java Embedded on your Raspberry Pi ?, you went to Fry's and picked up some jumper wires, LEDs, and resistors ?, you hooked up the wires, LED, and resistor the the correct pins ?, and now you want to start programming in Java on your RPi? Yes? ???????! OK, then... Here we go. You can use the following source code to blink your first LED on your RPi using Java. In the code you can see that I'm not using any complicated gpio libraries like wiringpi or pi4j, and I'm not doing any low-level pin manipulation like you can in C. And, I'm not using python (hell no!). This is Java programming, so we keep it simple (and more readable) than those other programming languages. See: Write Java code to do this In the Java code, I'm opening up the RPi Debian Wheezy well-defined file handles to control the GPIO ports. First I'm resetting everything using the unexport/export file handles. (On the RPi, if you open the well-defined file handles and write certain ASCII text to them, you can drive your GPIO to perform certain operations. See this GPIO reference). Next, I write a "1" then "0" to the value file handle of the GPIO0 port (see the previous pinout diagram). That makes the LED blink. Then, I loop to infinity. Easy, huh? import java.io.* /* * Java Embedded Raspberry Pi GPIO app */ package jerpigpio; import java.io.FileWriter; /** * * @author hinkmond */ public class JerpiGPIO { static final String GPIO_OUT = "out"; static final String GPIO_ON = "1"; static final String GPIO_OFF = "0"; static final String GPIO_CH00="0"; /** * @param args the command line arguments */ public static void main(String[] args) { FileWriter commandFile; try { /*** Init GPIO port for output ***/ // 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(GPIO_CH00); unexportFile.flush(); // Set the port for use exportFile.write(GPIO_CH00); exportFile.flush(); // Open file handle to port input/output control FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio"+GPIO_CH00+"/direction"); // Set port for output directionFile.write(GPIO_OUT); directionFile.flush(); /*--- Send commands to GPIO port ---*/ // Opne file handle to issue commands to GPIO port commandFile = new FileWriter("/sys/class/gpio/gpio"+GPIO_CH00+"/value"); // Loop forever while (true) { // Set GPIO port ON commandFile.write(GPIO_ON); commandFile.flush(); // Wait for a while java.lang.Thread.sleep(200); // Set GPIO port OFF commandFile.write(GPIO_OFF); commandFile.flush(); // Wait for a while java.lang.Thread.sleep(200); } } catch (Exception exception) { exception.printStackTrace(); } } } Hinkmond

  • JavaOne 2012 - The Power of Java 7 NIO.2

    - by Sharon Zakhour
    At JavaOne 2012, Mohamed Taman of e-finance gave a presentation highlighting the power of NIO.2, the file I/O APIs introduced in JDK 7. He shared information on how to get the most out of NIO.2, gave tips on migrating your I/O code to NIO.2, and presented case studies. The File I/O (featuring NIO.2) lesson in the Java Tutorials has extensive coverage of NIO.2 and includes the following topics: Managing Metadata Walking the File Tree Finding Files, including information on using PatternMatcher and globs. Watching a Directory for Changes Legacy File I/O Code includes information on migrating your code. From the conference session page, you can watch the presentation or download the materials.
