  • Prevent browser form submission when Wicket AjaxFormValidatingBehaviour validation fails

    - by Brian Laframboise
    I have a Page with a Wizard component. The user can navigate the panels of the wizard by using the next and previous buttons which I have performing full (non-ajax) form submissions so that the app is back-button friendly. When the next button is clicked, I would like to attempt ajax form validation (if javascript is enabled). I tried doing: nextButton.add( new AjaxFormValidatingBehavior( form, "onsubmit") ); to add such validation. The behaviour works - however, when validation errors occur the browser still submits the entire form. What is the Wicket way to prevent the browser from submitting the form in this case?

  • HTML Dynamic Number of Dropdowns

    - by Evilsithgirl
    I have this form on which I would like to create a dynamic number of dropdowns. I have a list of categorized applications which I would like each to have its own dropdown that submits data for each dropdown. The dropdown options will be the same for each. Here is my code. I am not sure how to pass the unique data to the server. As you can see I currently have an iteration over a list of applications that I would like to make each select in that iteration its own dropdown. Thanks in advance. <html:form action="/CategorizeApps.do"> <h3>Uncategorized</h3> <br/> Categorize each application using the dropdown menu then click categorize.<br/> <table class="list"> <thead> <tr class="controls"> <td><input type="submit" name="btnAction" value="Categorize"/></td> </tr> <tr class="fields"> <td>ID</td> <td>Name</td> <td></td> </tr> </thead> <tbody> <logic:iterate id="uncat" name="appsUncat" scope="session"> <tr class="hlist"> <td><bean:write property="id" name="uncat" scope="page"/></td> <td><bean:write property="name" name="uncat" scope="page"/></td> <td><select id="category" name="category"> <logic:iterate id="categories" name="Categories" scope="session"> <option value="<bean:write name="categories" property="id" scope="page"/>"><bean:write name="categories" property="name" scope="page"/></option> </logic:iterate> </select></td> </tr> </logic:iterate> </tbody> </table> </html:form>

  • Move and rename file in android

    - by Andre Fróes
    I am trying to copy a file to another folder in the android, but so far, i got no success. I manage to do so with a selected image and when taking a photo, but not with files. I've read and tried several solutions passed by the community (searched over the forum and the internet), but none of it was able to solve my problem when copying. First things first. I added the permissions to my manifest: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> after that, before copying a file, i print its filepath and the directory file path: 06-10 11:11:11.700: I/System.out(1442): /mimetype/storage/sdcard/Misc/Javascript erros for Submit and Plan buttons in IE.doc 06-10 11:11:11.710: I/System.out(1442): /storage/sdcard/mywfm/checklist-files both exists: to copy the file to the expected folder I used the FileUtils: try { FileUtils.copyFile(selectedFile, dir); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } The problem is: I get no exception and the file isn't there. I tried this solution either: How to move/rename file from internal app storage to external storage on Android? same thing, no exception, but no file either.

  • Is a point inside or outside a polygon which is on the surface of a globe

    - by richard
    How do I determine if a point is inside or outside a polygon that lies on the the surface of the earth? The inside of the polygon can be determined via the right hand rule, ie. the inside of the polygon is on your right hand side when you walk around the polygon. The polygon may Circle either pole Cross the 180 longitude Cover more than 50% of the globe As the globe is a sphere the normal ray crossing algorithms do not work correctly.

    Hi, I've a JEditorPane inside a JDialog. I'm loading a web page when this JDialog is loading. This web page is larger then the JEditorPane size.

  • How to inspect JSP request URL for String

    - by IAmYourFaja
    I have the following processor.jsp file: <% response.sendRedirect("http://buzz.example.com"); %> I want to change it so that it inspects the HTTP request URL for the presence of the word "fizz" and, if it exists, redirect the user to http://fizz.example.org instead. So something like: <% String reqUrl = request.getURL().toLowerCase(); String token = null; if(reqUrl.contains("fizz")) { token = "fizz"; } else { token = "buzz"; } String respUrl = "http://%%%TOKEN%%%.example.com".replace("%%%TOKEN%%%", token); response.sendRedirect(respUrl); %> However this doesn't work. Any ideas on what I should be using instead of request, or if I'm doing anything else wrong?

  • Converting WAR to EAR and other Glassfish stories

    - by Random
    Hello! I am really new in this so I hopefully don't make any terrible mistake. I apologize before hand if I have. In my project I was using tomcat and deploying WAR files. But now some bosses wants to deploy EAR files. So there we go. I first downloaded Glassfish (don't know if it's the apropiate application server for a newbie like me), instaled it and all (I even deployed the hello.war in the autodeploy _< ). Then prepared an EAR file. From what I know, I just need to create an Enterprise Application Project in Eclipse and add to the module my war file. This changes the application.xml file automatically (thanks eclipse project!). So I exported it to an EAR file and uploaded it to the glassfish server. Wonders of wonders, it doesn't work. I also tried deploying the old WAR file in this new shiny glassfish but it goes on http-404 not found error. The glassfish seems to say that my project is not in ~/domains/domain1/docroot. By the way I am using windows and I am aware of some problems between glassfish and windows due to some updating open files or such. So I have to questions: First, Am I doing the EAR package correctly? Second, Do I need to do some especial configuration to the glassfish server to deploy EAR and WAR files? Thanks!

  • Tomcat memory issue

    - by user305210
    Hello, I have noticed that my application that is running on Tomcat 5 starts with 1gig of memory and as soon as it starts receiving requests from client, the memory starts dropping until it is down to 100MBs and troubles start from there. I am looking at /manager/status page of tomcat under JVM section where "Free Memory", "Total Memory", "Max Memory" is listed. Is this an indicator of memory leak? Memory does not seem to be freed-up automatically even if there are no requests coming from client machines.

  • What does the exception "javax.servlet.jsp.JspException: Broken pipe" signify?

    - by Ruepen
    I'm getting the following error: javax.servlet.jsp.JspException: Broken pipe Now I have seen questions/answers with respects to the socket exception, but this error is coming from a different package. Any help is greatly appreciated. BTW, I am seeing quite a lot of these errors in a struts web app Weblogic Node logs and I am thinking that it has to do with end users closing their web browser before the page reloads/executes the next step (database transaction which takes quite a bit of time to execute, anywhere from 30 seconds to 4 mins).

  • Recommended ways of Importing a maven project to IDE ?

    - by Tony
    Many IDEs supports to import maven projects directly, but maven has a maven-eclipse-plugin, when you run : mvn eclipse:eclipse It will generate eclipse project settings ,then you can import as generic eclipse project. Which one is better? I prefer the first one, as my IDE is eclipse 3.5 shiped with WTP 3.1 and m2eclipse, I don't know if maven-eclipse-plugin support WTP 3.1 project settings ? If I don't import correct project settings, I don't think eclipse will recognize my project,when I deploy a web application, it ususally can't find webroot folder.

  • JSF Pages call ManagedBeans that are not defined on the page and call all getters sometimes more tha

    - by Bill Leeper
    I have several JSF pages that are initializing and accessing ManagedBeans that are not even used on that page. This is creating a really hairy problem for initialization. I either have to make them all session scope and continually make calls to re-inialize or take the performance hit of having them read large amounts of data from the DB whenever they decide to initialize. Some of the managed beans being accessed are not even defined on the page in question. I have done some optimization based on comments related to multiple calls to getters, but I still have the issue that I have a very specialized (and expensive to initialize) bean that is getting called when I don't want it initialized. Any insight into why/what JSF calls might do something like this. I have a very complex page making use of JSTL, Tomahawk and standard JSF tags. I could include code, but its very complex and sensitive in nature.

  • Using an empty column as a divider in a JTable.

    - by Catalina Island
    I'm trying to use an empty column as a divider between pairs of columns in a JTable. Here's a picture and code for what I have so far. I know I can change the look using a custom TableCellRenderer. Before I go down that road, is there a better way to do this? Any ideas appreciated. import javax.swing.*; import javax.swing.table.*; public class TablePanel extends JPanel { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { JFrame f = new JFrame("TablePanel"); f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); f.add(new TablePanel()); f.pack(); f.setVisible(true); } }); } public TablePanel() { TableModel dataModel = new MyModel(); JTable table = new JTable(dataModel); table.getColumnModel().getColumn(MyModel.DIVIDER).setMaxWidth(0); JScrollPane jsp = new JScrollPane(table); jsp.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS); this.add(jsp); } private static class MyModel extends AbstractTableModel { private static final int DIVIDER = 2; private final String[] names = { "A1", "A2", "", "B1", "B2" }; @Override public int getRowCount() { return 32; } @Override public int getColumnCount() { return names.length; } @Override public String getColumnName(int col) { if (col == DIVIDER) return ""; return names[col]; } @Override public Object getValueAt(int row, int col) { if (col == DIVIDER) return ""; return (row + 1) / 10.0; } @Override public Class<?> getColumnClass(int col) { if (col == DIVIDER) return String.class; return Number.class; } } }

  • Wicket: Where to add components? Constructor? Or onBeforeRender?

    - by gmallett
    I'm a Wicket newb. This may just be my ignorance of the Wicket lifecycle so please enlighten me! My understanding is that Wicket WebPage objects are instantiated once and then serialized. This has led to a point of confusion for me, see below. Currently I have a template class which I intend to subclass. I followed the example in the Wicket docs demonstrating how to override the template's behavior in the subclass: protected void onBeforeRender() { add(new Label("title", getTitle())); super.onBeforeRender(); } protected String getTitle() { return "template"; } Subclass: protected String getTitle() { return "Home"; } This works very well. What's not clear to me are the "best practices" for this. It seems like onBeforeRender() is called on every request for the page, no? This seems like there would be substantially more processing done on a page if everything is in onBeforeRender(). I could easily follow the example of the other Wicket examples and add some components in the constructor that I do not want to override, but then I've divided by component logic into two places, something I'm hesitant to do. If I add a component that I intend to be in all subclasses, should I add it to the constructor or onBeforeRender()?

  • Android: how to get the walking distance between two geo coordinats?

    - by wei
    I used this query URL http://maps.google.com/maps?q=from+A+to+B&output=kml ,which is given in the answer to this question. But after I tried it, it doesn't work with coordinates. It works with address names tho. I guess I could use google's geocoding to get the addresses first. But I wonder if there is another way to get the walking distance between two coordinates?
