  • Wicket and Spring Intergation

    - by Vinothbabu
    I have a wicket contact form, and i receive the form object. Now i need to pass this object to Spring Service. package com.mysticcoders.mysticpaste.web.pages; import org.apache.wicket.markup.html.WebPage; import org.apache.wicket.markup.html.form.Form; import org.apache.wicket.markup.html.form.TextField; import org.apache.wicket.markup.html.panel.FeedbackPanel; import com.mysticcoders.mysticpaste.model.Contact; import org.apache.wicket.model.CompoundPropertyModel; import com.mysticcoders.mysticpaste.services.IContact; public class FormPage extends WebPage { private Contact contact; private IContact icontact; public FormPage() { // Add a FeedbackPanel for displaying our messages FeedbackPanel feedbackPanel = new FeedbackPanel("feedback"); add(feedbackPanel); Form<Object> form = new Form<Object>("contactForm", new CompoundPropertyModel<Object>(contact)) { private static final long serialVersionUID = 1L; protected void onSubmit(Contact contact) { icontact.saveContact(contact); } }; form.add(new TextField<Object>("name")); form.add(new TextField<Object>("email")); form.add(new TextField<Object>("country")); form.add(new TextField<Object>("age")); add(form); // add a simple text field that uses Input's 'text' property. Nothing // can go wrong here } } I am pretty much sure that we need to do something with application-context xml where i may need to wire out. My Application-context.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <bean id="WicketApplication" class="com.mysticcoders.mysticpaste.web.pages.WicketApplication" /> </beans> My Question is simple. What should i do which can make my onSubmit method call the Spring Service? Could someone let me know what needs to modified in my Application-context.xml so that once the form gets submitted, it contacts the Spring Service class.

  • Using Session Bean provided data on JSF welcome page

    - by takachgeza
    I use JSF managed beans calling EJB methods that are provide data from database. I want to use some data already on the welcome page of the application. What is the best solution for it? EJBs are injected into JSF managed beans and it looks like the injection is done after executing the constructor. So I am not able to call EJB methods in the constructor. The normal place for EJB call is in the JSF action methods but how to call such a method prior to loding the first page of the application? A possible solution would be to call the EJB method conditionally in a getter that is used on the welcome page, for example: public List getProductList(){ if (this.productList == null) this.productList = myEJB.getProductList(); return this.productList; } Is there any better solution? For example, in some config file?

  • How do I migrate a ManyToOne to a ManyToMany relationship in Hibernate?

    - by spderosso
    I have a instance field of a class X that is mapped using Hibernate as a Many to One relationship. E.g: public class X{ ... @ManyToOne(optional=false) private Y iField; ... } That is correctly working with a particular schema. I know want to change this instance field iField to a List and a Many to Many relationship. public class X{ ... @ManyToMany(optional=false) private List<Y> iField; ... } What steps should I follow? Do I have to change the schema? in which way? In case you need more info let me know. Thanks!

  • Message Queue with 'Message Barrier' Feature?

    - by Lajos Nagy
    Is there a message queue implementation that allows breaking up work into 'batches' by inserting 'message barriers' into the message stream? Let me clarify. No messages after a message barrier should be delivered to any consumers of the queue, until all messages before the barrier are consumed. Sort of like a synchronization point. I'd also prefer if all consumers received notification when they reached a barrier. Anything like this out there?

  • Hibernate generate POJOs with Equals

    - by jschoen
    We are using hibernate in a new project where we use the hibernate.reveng.xml to create our *.hbm.xml files and POJOs after that. We want to have equals methods in each of our POJOs. I found that you can use <meta attribute="use-in-equals">true</meta> in your hbm files to mark which properties to use in the equals. But this would mean editing alot of files, and then re-editing the files again in the future if/when we modify tables or columns in our DB. So I was wondering if there is a way to place which properties to use in the equals method for each pojo(table) in the hibernate.reveng.xml file?

  • Get name of currently executing test in JUnit 4

    - by Dave Ray
    In JUnit 3, I could get the name of the currently running test like this: public class MyTest extends TestCase { public void testSomething() { System.out.println("Current test is " + getName()); ... } } which would print "Current test is testSomething". Is there any out-of-the-box or simple way to do this in JUnit 4? Background: Obviously, I don't want to just print the name of the test. I want to load test-specific data that is stored in a resource with the same name as the test. You know, convention over configuration and all that. Thanks!

  • How to set Atomikos to not write to console logs?

    - by peter
    Atomikos is quite verbose when used. There seems to be lots of INFO messages (mostly irrelevant for me) that the transaction manager writes out to the console. The setting in the transaction.properties that is suppose to control the level of messaging com.atomikos.icatch.console_log_level does not seem to have any effect, since even when set to WARN (or ERROR) the INFO messages are still logged. Also the log4j settings for com.atomikos and atomikos seem to be ignored. Does anyone manage to turn off the INFO logs on the console with Atomikos?. How? Thanks Peter

  • understanding this regex

    - by DarthVader
    I m trying to understand what the following does. ^([^=]+)(?:(?:\\=)(.+))?$ Any ideas? This is being used here. Obviously it s command line parser but i m trying to understand the syntax so i can actually run the program. This is from commandline-jmxclient , they have no documents on setting JMX properties but in their source code, there is such an option, so i just want to understand how i can invoke that method. Matcher m = Client.CMD_LINE_ARGS_PATTERN.matcher(command); if ((m == null) || (!m.matches())) { throw new ParseException("Failed parse of " + command, 0); } this.cmd = m.group(1); if ((m.group(2) != null) && (m.group(2).length() > 0)) this.args = m.group(2).split(","); else this.args = null;

  • How to set JtextArea to keep fixed no of rows?

    - by Hippo
    How can i keep no of rows constant in text area. I need to create a console window for my application. If rows exceeds predefined no of rows first rows must get disposed. As if first written row will be destroyed first when i append anything which exceeds no of rows set. One more thing , i need to keep vertical scroll bar. That means no of rows must not be the whatever rows are visible when text area it opened. For example : - no of visible rows on view port are 30. It should keep 120 rows information, which will can be seen with the help of scroll bar.

  • append files to an archive without reading/rewriting the whole archive

    - by bene
    I've got many files that I want to store in a single archive file. My first approach was to store the files in a gzipped tarball. The problem is, that I've to rewrite the whole archive if a single file is added. I could get rid of the gzip compression, but adding a file would still be expensive. What other archive format would you suggest that allows fast append operations?

  • Classloading order in JBoss

    - by Spiderman
    I'd like to know if the default behavior of JBoss server (4.2.3.GA in my case) is loading the classes in parent-first or parent-last mode. And in case it work as I suspect in parent-last mode (i.e. first trying to load classes from the application's WEB-INF/lib and only if they are not found go to server\lib), how can I configure it to work in the opposite- first trying to load classes from outside and only looking inside the application afterwards.

I know that JComboBox need to be something like that: JComboBox combo = new JComboBox(itemTypeArray.values()); JOptionPane.showMessageDialog( null, combo,"Please Enter Item Type", `JOptionPane.QUESTION_MESSAGE);` What am I doing wrong?

  • Android - Correspondence between ImageView coordinates and Bitmap Pixels

    - by Matteo
    In my application I want the user to be able to select some content of an Image contained inside an ImageView. To select the content I subclassed the ImageView class making it implement the OnTouchListener so to draw over it a rectangle with borders decided by the user. Here is an example of the result of the drawing (to have an idea you can think of it as when you click with the mouse on your desktop and drag the mouse): Now I need to determine which pixels of the Bitmap image correspond to the selected part. It's kind of easy to determine which are the points of the ImageView belonging to the rectangle, but I don't know how to get the correspondent pixels, since the ImageView has a different aspect ratio than the original image. I followed the approach described especially here, but also here, but am not fully satisfied because in my opinion the correspondence made is 1 on 1 between pixels and points on the ImageView and does not give me all the correspondent pixels on the original image to the selected area. Calling hoveredRect the rectangle on the ImageView the points inside of it are: class Point { float x, y; @Override public String toString() { return x + ", " + y; } } Vector<Point> pointsInRect = new Vector<Point>(); for( int x = hoveredRect.left; x <= hoveredRect.right; x++ ){ for( int y = hoveredRect.top; y <= hoveredRect.bottom; y++ ){ Point pointInRect = new Point(); pointInRect.x = x; pointInRect.y = y; pointsInRect.add(pointInRect); } } How can I obtain a Vector<Pixels> pixelsInImage containing the correspondent pixels?

  • lwjgl 101: How can I write applets?

    - by Vuntic
    I have a working app in lwjgl. It doesn't do much yet; I've just started, but it does compile and run like it's supposed to. I want to make it into an applet. I've followed the guide here, and I have an applet that runs nicely and displays text and such in the applet area and can access the functions of lwjgl (like Sys.alert), but I can't figure out how to get opengl to actually render. I've tried extending an AWTGLCanvas and calling this.add(myAWTGLCanvas), where this is the Applet that I'm using, but... nothing. The initGL() and paintGL() methods never get called. I wonder if I'm supposed to be doing something with Display, but that's not for applets, right? Help? Also: This counts as a "beginner" question, right? Edit: Here's a simplified version of what I have.
