  • Can we only use the front-end of wordpress without any front-end ?

    - by Tristan
    Hello, i just asked a question few minutes ago which led me to this one : I want to know if there is any chance to use only the back-end of wordpress ? I mean, link my admin interface to post news link my visitor interface on my website to the wordpress news so the visitor can access the news So the visitor never find out that i'm using wordpress to generate the news and handle their comments and write my news ? Maybe it's possible but there is no point by doing so ? Thank you

  • Context Sensitive JTable

    - by Geertjan
    Here's a plain old JTable on the NetBeans Platform. Whenever the toolbar button is clicked, information about the currently selected row is displayed in the status bar: Normally, the above would be achieved in NetBeans Platform applications via Nodes publishing their underlying business object when the selection changes. In this case, there are no Nodes at all. There's only a JTable and a DefaultTableModel, i.e., all pure Java Swing. So, how does it work? To follow the logic, it makes sense to create the example yourself, starting with the Stock object: public class Stock {     String name;     String desc;     public Stock() {     }     public Stock(String name, String desc) {         this.name = name;         this.desc = desc;     }     public String getDesc() {         return desc;     }     public String getName() {         return name;     }     public void setDesc(String desc) {         this.desc = desc;     }     public void setName(String name) {         this.name = name;     } } Next, create a new Window Component via the wizard and then rewrite the constructor as follows: public final class MyWindowTopComponent extends TopComponent {     private final InstanceContent ic = new InstanceContent();     public MyWindowTopComponent() {         initComponents();         //Statically create a few stocks,         //in reality these would come from a data source         //of some kind:         List<Stock> list = new ArrayList();         list.add(new Stock("AMZN", "Amazon"));         list.add(new Stock("BOUT", "About.com"));         list.add(new Stock("Something", "Something.com"));         //Create a JTable, passing the List above         //to a DefaultTableModel:         final JTable table = new JTable(StockTableModel (list));         //Whenever the mouse is clicked on the table,         //somehow construct a new Stock object //(or get it from the List above) and publish it:         table.addMouseListener(new MouseAdapter() {             @Override             public void mousePressed(MouseEvent e) {                 int selectedColumn = table.getSelectedColumn();                 int selectedRow = table.getSelectedRow();                 Stock s = new Stock();                 if (selectedColumn == 0) {                     s.setName(table.getModel().getValueAt(selectedRow, 0).toString());                     s.setDesc(table.getModel().getValueAt(selectedRow, 1).toString());                 } else {                     s.setName(table.getModel().getValueAt(selectedRow, 1).toString());                     s.setDesc(table.getModel().getValueAt(selectedRow, 0).toString());                 }                 ic.set(Collections.singleton(s), null);             }         });         JScrollPane scrollPane = new JScrollPane(table);         add(scrollPane, BorderLayout.CENTER);         //Put the dynamic InstanceContent into the Lookup:         associateLookup(new AbstractLookup(ic));     }     private DefaultTableModel StockTableModel (List<Stock> stockList) {         DefaultTableModel stockTableModel = new DefaultTableModel() {             @Override             public boolean isCellEditable(int row, int column) {                 return false;             }         };         Object[] columnNames = new Object[2];         columnNames[0] = "Symbol";         columnNames[1] = "Name";         stockTableModel.setColumnIdentifiers(columnNames);         Object[] rows = new Object[2];         ListIterator<Stock> stockListIterator = stockList.listIterator();         while (stockListIterator.hasNext()) {             Stock nextStock = stockListIterator.next();             rows[0] = nextStock.getName();             rows[1] = nextStock.getDesc();             stockTableModel.addRow(rows);         }         return stockTableModel;     }     ...     ...     ... And now, since you're publishing a new Stock object whenever the user clicks in the table, you can create loosely coupled Actions, like this: @ActionID(category = "Edit", id = "org.my.ui.ShowStockAction") @ActionRegistration(iconBase = "org/my/ui/Datasource.gif", displayName = "#CTL_ShowStockAction") @ActionReferences({     @ActionReference(path = "Menu/File", position = 1300),     @ActionReference(path = "Toolbars/File", position = 300) }) @Messages("CTL_ShowStockAction=Show Stock") public final class ShowStockAction implements ActionListener {     private final Stock context;     public ShowStockAction(Stock context) {         this.context = context;     }     @Override     public void actionPerformed(ActionEvent ev) {         StatusDisplayer.getDefault().setStatusText(context.getName() + " / " + context.getDesc());     } }

  • YouTube: Promotional AgroSense Movie

    - by Geertjan
    Here's a cool YouTube promotional movie on AgroSense created by Ordina in the Netherlands. AgroSense is an open source Java system for the precision agriculture industry, which won the IT Environment Award in the Netherlands last week: If your understanding of Dutch limits your appreciation of the movie above, here's a rough translation, together with the names of the speakers in the movie: Precision agriculture, an innovative form of agriculture in which local variations in soil, crop, and atmosphere are taken into account, is the high-tech sustainable agriculture of tomorrow. The use of fertilizer, water, and energy can in this way be significantly reduced. "If, ten or twenty years from now, we are to continue having our agricultural industry in good shape, and in a continuing state of health, we'll need to register and work with data because if we want to enable crops to provide higher value, we'll need to create higher levels of transparency throughout the agriculture chain." Lenus Hamster, farmer in Nieuwolda Groningen "Industry is becoming increasingly data intensive. By combining pragmatic usefulness with innovative sustainability, AgroSense offers the Netherlands the possibility to continue being a leading player in the agrofood sector." Art Lighthart, Architect at Ordina AgroSense offers an open source solution in which all services for precision agriculture are brought together. In 2012, co-operation is being sought with organizations to make AgroSense available to around 10,000 Dutch farmers in the arable crop sector. By the way, the last sentence above implies the NetBeans Platform will be used by around 10,000 Dutch farmers.

  • Handy Tool for Code Cleanup: Automated Class Element Reordering

    - by Geertjan
    You're working on an application and this thought occurs to you: "Wouldn't it be cool if I could define rules specifying that all static members, initializers, and fields should always be at the top of the class? And then, whenever I wanted to, I'd start off a process that would actually do the reordering for me, moving class elements around, based on the rules I had defined, automatically, across one or more classes or packages or even complete code bases, all at the same time?" Well, here you go: That's where you can set rules for the ordering of your class members. A new hint (i.e., new in NetBeans IDE 7.3), which you need to enable yourself because by default it is disabled, let's the IDE show a hint in the Java Editor whenever there's code that isn't ordered according to the rules you defined: The first element in a file that the Java Editor identifies as not matching your rules gets a lightbulb hint shown in the left sidebar: Then, when you click the lightbulb, automatically the file is reordered according to your defined rules. However, it's not much fun going through each file individually to fix class elements as shown above. For that reason, you can go to "Refactor | Inspect and Transform". There, in the "Inspect and Transform" dialog, you can choose the hint shown above and then specify that you'd like it to be applied to a scope of your choice, which could be a file, a package, a project, combinations of these, or all of the open projects, as shown below: Then, when Inspect is clicked, the Refactoring window shows all the members that are ordered in ways that don't conform to your rules: Click "Do Refactoring" above and, in one fell swoop, all the class elements within the selected scope are ordered according to your rules.

  • Decreasing the Height of the PinkMatter Flamingo Ribbon Bar

    - by Geertjan
    The one and only thing prohibiting wide adoption of PinkMatter's amazing Flamingo ribbon bar integration for NetBeans Platform applications (watch the YouTube movie here and follow the tutorial here) is... the amount of real estate taken up by the height of the taskpane: I was Skyping with Bruce Schubert about this and he suggested that a first step might me to remove the application menu. OK, once that had been done there was still a lot of height: But then I configured a bit further and now have this, which is pretty squishy but at least shows there are possibilities: How to get to the above point? Get the PinkMatter Flamingo ribbon bar from java.net (http://java.net/projects/nbribbonbar), which is now the official place where it is found, and then look in the "Flaming Integration" module. There you'll find com.pinkmatter.modules.flamingo.LayerRibbonComponentProvider. Do the following: Comment out "addAppMenu(ribbon);" in "createRibbon()". That's the end of the application menu. Change the "addTaskPanes(JRibbon ribbon)" method from this... private void addTaskPanes(JRibbon ribbon) { RibbonComponentFactory factory = new RibbonComponentFactory(); for (ActionItem item : ActionItems.forPath("Ribbon/TaskPanes")) {// NOI18N ribbon.addTask(factory.createRibbonTask(item)); } } ...to the following: private void addTaskPanes(JRibbon ribbon) { RibbonComponentFactory factory = new RibbonComponentFactory(); for (ActionItem item : ActionItems.forPath("Ribbon/TaskPanes")) { // NOI18N RibbonTask rt = factory.createRibbonTask(item); List<AbstractRibbonBand<?>> bands = rt.getBands(); for (AbstractRibbonBand arb : bands) { arb.setPreferredSize(new Dimension(40,60)); } ribbon.addTask(rt); } } Hurray, you're done. Not a very great result yet, but at least you've made a start in decreasing the height of the PinkMatter Flamingo ribbon bar. If anyone gets further with this, I'd be very happy to hear about it!

  • JavaOne Russia: Great Line Up

    - by Geertjan
    I'm (we're) in New York, a week of vacation. (Growing list of photos can be found here.) A week in Brooklyn, and around, flea markets, book stores, museums, music. One of several highlights will be seeing "Death of a Salesman" with Philip Seymour Hoffman in the main role, tomorrow. However, mentally, at least partly, I'm in Moscow, at JavaOne Moscow, 17 & 18 April. http://www.oracle.com/javaone/ru-en/index.html I'm doing two items there, thankfully on the first day, I always think the sooner the better: Tuesday 12:30 - 13:15 -- Unlocking the Java EE 6 Platform (in the Keynote Hall) Tuesday 16:30 - 18:15 -- Rapid Corporate Desktop Development (in HOL Room) Several speakers I'm looking forward to seeing there include Bert Ertman who will be talking about Spring/Java EE 6 migration, Dalibor Topic talking about Lambda expressions in JDK 8, Arun Gupta with his Java EE 6 HOL (appears to be a partial overlap with my session), and various others. And I hope I will make it to Angela Caicedo's HOL on JavaFX. The whole program, which is available via the link above, indicates that many (dare I say "most"?) of the sessions will be using NetBeans in one way or another. Looks like it will be a great conference.

  • Baseline for GIS Applications

    - by Geertjan
    The application I introduced here yesterday can best be understood via its author's explanation: "As I developed several different WorldWind-based applications, I noticed that they all started out the same. Terramenta was born so I wouldn't have to recreate the baseline every time, I could just provide NetBeans plugin modules to introduce the new features required by different projects." So, to try it out for myself, I checked out the sources from the Mercurial repo today, built them, and ran them. hg clone https://bitbucket.org/heidtmare/terramenta On Windows, things worked fine, on Ubuntu they didn't because the relevant native libraries aren't provided yet out of the box. Here's the result: The above provides the WorldWind globe, together with all the standard options, e.g., for showing names and other WorldWind features, together with several features that I don't understand yet, such as tools for creating shapes and a recorder for replaying sequences. The complete application is like this, i.e., one single functionality module is provided, which exposes several API packages that can be extended: It would really be cool if the above module could also be added to a Maven-based application via a reference to a Maven repository, in the way that Timon Veenstra and the AgroSense team have made available their GeoViewer. One cool thing from the GeoViewer solution is the Flamingo menubar, which I added to Terramenta by simply putting the dependency below into the application POM: <dependency>    <groupId>nl.cloudfarming.client</groupId>    <artifactId>menu</artifactId>    <version>1.0.24</version></dependency> The result, without doing anything other than the above: I am looking forward to helping to document the use cases and developer scenarios for Terramenta! Something like this, created by Timon to demonstrate the GeoViewer use case would be cool to have: http://java.net/projects/agrosense/pages/ExampleGeoviewerNormal

  • 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.

  • How to Draw Lines on the Screen (Part 2)

    - by Geertjan
    In part 1, I showed how you can click on the screen to create widgets and then connect those widgets together. But that's not really drawing, is it? (And I'm surprised nobody made that point in the comments to that blog entry.) Drawing doesn't really revolve around connecting dots together. It's more about using a free-flow style and being able to randomly write stuff onto a screen, without constraints. Something like this: I achieved the above by changing one line of code from the original referred to above. Instead of using a "mousePressed" event, I'm now using a "mouseDragged" event. That's all. And now the widgets are created when I drag my mouse on the scene. (I removed the rectangular select action, since that's also invoked during dragging and since that doesn't apply to the above scenario.) Now, the next step is to rewrite the NetBeans Platform Paint Application Tutorial, so that the Visual Library is used. That would be pretty cool.

  • How To Make Moving News Bar in Windows Forms Application without Timer

    - by Ehab Sutan
    I'm making a desktop application in C# which contains a moving News Bar labels. I'm using a timer to move these labels but the problem is that when i make the interval of this timer low (1-10 for example) the application takes very high percentage of CPU Usage, And when i make it higher(200 -500 ) the movement of the labels becomes intermittent or not smooth movement even that the user may not be able to read the news in Comfortable way. ((More Information)) it is Windows form application. the way i move the labels is as follows : the news items from RSS feeds are represented in a group of linklabels. All these linklabels are added to a flowlayout container. The timer moves the whole flowlayout container. I found this way according to my knowledge the best way to making the news bar. If you have better idea or solution please help

  • Devoxx 2011: Java EE 6 Hands-on Lab Delivered

    - by arungupta
    I, along with Alexis's help, delivered a Java EE 6 hands-on lab to a packed room of about 40+ attendees at Devoxx 2011. The lab was derived from the OTN Developer Days 2012 version but added lot more content to showcase several Java EE 6 technologies. The problem statement from the lab document states: This hands-on lab builds a typical 3-tier Java EE 6 Web application that retrieves customer information from a database and displays it in a Web page. The application also allows new customers to be added to the database as well. The string-based and type-safe queries are used to query and add rows to the database. Each row in the database table is published as a RESTful resource and is then accessed programmatically. Typical design patterns required by a Web application like validation, caching, observer, partial page rendering, and cross-cutting concerns like logging are explained and implemented using different Java EE 6 technologies. The lab covered Java Persistence API 2, Servlet 3, Enterprise JavaBeans 3.1, JavaServer Faces 2, Java API for RESTful Web Services 1.1, Contexts and Dependency Injection 1.0, and Bean Validation 1.0 over 47 pages of detailed self-paced instructions. Here is the complete Table of Contents: The lab can be downloaded from here and requires only NetBeans IDE "All" or "Java EE" version, which includes GlassFish anyway. All the feedback received from the lab has been incorporated in the instructions and bugs filed (Updated 49559, 205232, 205248, 205256). 80% of the attendees could easily complete the lab and some even completed in much less than 3 hours. That indicates that either more content needs to be added to the lab or the intellectual level of the attendees at the conference was pretty high. I think the lab has enough content for 3 hours but we moved at a much more faster pace so I conclude on the latter. Truly a joy to conduct a lab to 40 Devoxxians! Another related lab that might be handy for folks is "Develop, Deploy, and Monitor your Java EE 6 applications using GlassFish 3.1 Cluster". It explains how: Create a 2-instance GlassFish cluster Front-end with a Web server and a load balancer Demonstrate session replication and fail over Monitor the application using JavaScript The complete lab instructions and source code are available and you can try them. I plan to continue evolving the contents for the Java EE 6 hands-on lab to cover more technologies and features and will announce them on this blog. Let me know on what else would you like to see in the future versions.

  • JGridView (Part 2)

    - by Geertjan
    The second sample in the JGrid download is a picture viewer that needs to be seen to be believed. Here it is, integrated into a NetBeans Platform application (click to enlarge it): When you mouse over the images, they change, showing several different images instantaneously. Here's the explorer view above, mainly making use of code from the sample: public class JGridView extends JScrollPane { @Override public void addNotify() { super.addNotify(); final ExplorerManager em = ExplorerManager.find(this); if (em != null) { final JGrid grid = new JGrid(); Node root = em.getRootContext(); final Node[] nodes = root.getChildren().getNodes(); final PicViewerObject[] pics = new PicViewerObject[nodes.length]; for (int i = 0; i < nodes.length; i++) { Node node = nodes[i]; pics[i] = node.getLookup().lookup(PicViewerObject.class); } grid.getCellRendererManager().setDefaultRenderer(new PicViewerRenderer()); grid.setModel(new DefaultListModel() { @Override public int getSize() { return pics.length; } @Override public Object getElementAt(int i) { return pics[i]; } }); grid.setFixedCellDimension(160); grid.addMouseMotionListener(new MouseAdapter() { int lastIndex = -1; @Override public void mouseMoved(MouseEvent e) { if (lastIndex >= 0) { Object o = grid.getModel().getElementAt(lastIndex); if (o instanceof PicViewerObject) { Rectangle r = grid.getCellBounds(lastIndex); if (r != null && !r.contains(e.getPoint())) { ((PicViewerObject) o).setMarker(false); grid.repaint(r); } } } int index = grid.getCellAt(e.getPoint()); if (index >= 0) { Object o = grid.getModel().getElementAt(index); if (o instanceof PicViewerObject) { Rectangle r = grid.getCellBounds(index); if (r != null) { ((PicViewerObject) o).setFraction(((float) e.getPoint().x - (float) r.x) / (float) r.width); ((PicViewerObject) o).setMarker(true); lastIndex = index; grid.repaint(r); } } } } }); grid.getSelectionModel().addListSelectionListener(new ListSelectionListener() { @Override public void valueChanged(ListSelectionEvent e) { //Somehow compare the selected item //with the list of books and find a matching book: int selectedIndex = grid.getSelectedIndex(); for (int i = 0; i < nodes.length; i++) { int picId = pics[i].getId(); if (selectedIndex == picId) { try { em.setSelectedNodes(new Node[]{nodes[i]}); } catch (PropertyVetoException ex) { Exceptions.printStackTrace(ex); } } } } }); setViewportView(grid); } } } The next step is to create a generic JGridView that will handle any kind of object automatically.

  • Oredev 2011 Trip Report

    - by arungupta
    Oredev had its seventh annual conference in the city of Malmo, Sweden last week. The name "Oredev" signifies to the part that Malmo is connected with Copenhagen with Oresund bridge. There were about 1000 attendees with several speakers from all over the world. The first two days were hands-on workshops and the next three days were sessions. There were different tracks such as Java, Windows 8, .NET, Smart Phones, Architecture, Collaboration, and Entrepreneurship. And then there was Xtra(ck) which had interesting sessions not directly related to technology. I gave two slide-free talks in the Java track. The first one showed how to build an end-to-end Java EE 6 application using NetBeans and GlassFish. The complete instructions to build the application are explained in detail here. This 3-tier application used Java Persistence API, Enterprsie Java Beans, Servlet, Contexts and Dependency Injection, JavaServer Faces, and Java API for RESTful Services. The source code built during the application can be downloaded here (LINK TBD). The second session, slide-free again, showed how to take a Java EE 6 application into production using GlassFish cluster. It explained: Create a 2-instance GlassFish cluster Front-end with a Web server and a load balancer Demonstrate session replication and fail over Monitor the application using JavaScript The complete instructions for this session are available here. Oredev has an interesting way of collecting attendee feedback. The attendees drop a green, yellow, or red card in a bucket as they walk out of the session. Not everybody votes but most do. Other than the instantaneous feedback provided on twitter, this mechanism provides a more coarse grained feedback loop as well. The first talk had about 67 attendees (with 23 green and 7 yellow) and the second one had 22 (11 green and 11 yellow). The speakers' dinner is a good highlight of the conference. It is arranged in the historic city hall and the mayor welcomed all the speakers. As you can see in the pictures, it is a very royal building with lots of history behind it. Fortunately the dinner was a buffet with a much better variety unlike last year where only black soup and geese were served, which was quite cultural BTW ;-) The sauna in 85F, skinny dipping in 35F ocean and alternating between them at Kallbadhus is always very Swedish. Also spent a short evening at a friend's house socializing with other speaker/attendees, drinking Glogg, and eating Pepperkakor.  The welcome packet at the hotel also included cinnamon rolls, recommended to drink with cold milk, for a little more taste of Swedish culture. Something different at this conference was how artists from Image Think were visually capturing all the keynote speakers using images on whiteboards. Here are the images captured for Alexis Ohanian (Reddit co-founder and now running Hipmunk): Unfortunately I could not spend much time engaging with other speakers or attendees because was busy preparing a new hands-on lab material. But was able to spend some time with Matthew Mccullough, Micahel Tiberg, Magnus Martensson, Mattias Karlsson, Corey Haines, Patrick Kua, Charles Nutter, Tushara, Pradeep, Shmuel, and several other folks. Here are a few pictures captured from the event: And the complete album here: Thank you Matthias, Emily, and Kathy for putting up a great show and giving me an opportunity to speak at Oredev. I hope to be back next year with a more vibrant representation of Java - the language and the ecosystem!
