  • Problem with JSON, Struts 2 and Ajax.

    - by Javi
    Hello, I have an apllication with Struts 2, Spring and I want to send JSON as a response to an Ajax request, but my server in not sending the JSON in the response. I have this base package: <package name="myApp-default" extends="struts-default"> <result-types> <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" /> <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"> <param name="enableGZIP">true</param> <param name="noCache">true</param> <param name="defaultEncoding">ISO-8859-1</param> </result-type> </result-types> </package> And another package which extends the previous one. <package namespace="/rest" name="rest" extends="myApp-default"> <action name="login" class="restAction" method="login"> <result type="json"/> </action> So I call with jQuery Ajax and debugging it I see it enters in the Action restAction in the method login and it also enters in the method getJsonData() because I have set two breakpoints and the program is stopped first in login and then in getJsonData. public class RestAction extends BaseAction { private String login; private String password; private String jsonData; public String login() { jsonData = "changed"; return Action.SUCCESS; } //I ommit getter/setters for login and password @JSON(name="jsonData") public String getJsonData() { return jsonData; } public void setJsonData(String jsonData) { this.jsonData = jsonData; } } My ajax looks like this: $.ajax({type: 'GET', url: this_url, data: pars, cache:false, success: handleResponse, error: handleError}); With firebug I see that the response to my request is completely void (though I have seen that the data saved in pars variable has been populated to the action and the methods have been executed correctly). And maybe for that reason my ajax enters in my handleError function where xmlHttpRequest.readyState is 4 and xmlHttpRequest.status is 0. Can anyone tell me what may the problem be? Thanks.

  • Catering for client's web-hosting needs, minus the headaches ?

    - by julien
    I'll be trying to sell my Ruby on Rails development skills to small local businesses. It seems I'd be shooting myself in the foot if I couldn't manage to put their apps into production, in fact catering for this would be a selling point. However, I do not want to bill every client monthly for the cost of their hosting, they would have to be the contract holders with the hosting service, and I'd only consult if they needed technical help when scaling. I've looked on one hand at cloud platforms, like engine yard, which seem like they would be too costly for the smaller clients, and on the other hand at vps providers which seem they would not be client friendly enough. Has anyone faced the same issue and come up with a decent solution ?

  • WCF Certificate issue

    - by Morgeh
    I am developing a WCF service on my local computer using Visual Studios built in ASP.NET development sever and I'm having issues creating and using temporary Certificates. I have created a cert call TempCA and added it to the Trusted Root Certificate folder and I have created another called SignedByCA which has been added to the personal folder. The service config file has been set up to use SignedByCA but when I run the service I get the following error. The certificate 'CN=SignedByCA' must have a private key that is capable of key exchange. The process must have access rights for the private key. I have tried using WinHttpCertCfg.exe to give other users access to the key but I have since found out that WinHttpCertCfg.exe has be deprecated in windows Vista. Has anyone had this issue before in a similar circumstance??

  • Adding image to RichTextBox programatically does not show in Xaml property

    - by rotary_engine
    Trying to add an image to a RichTextBox progamatically from a Stream. The image displays in the text box, however when reading the Xaml property there is no markup for the image. private void richTextBox3_Drop(object sender, DragEventArgs e) { if (e.Data.GetDataPresent(DataFormats.FileDrop)) { FileInfo[] files = (FileInfo[])e.Data.GetData(DataFormats.FileDrop); using (Stream s = files[0].OpenRead()) { InlineUIContainer container = new InlineUIContainer(); BitmapImage bmp = new BitmapImage(); bmp.SetSource(s); Image img = new Image(); img.SetValue(Image.SourceProperty, bmp); container.Child = img; richTextBox3.Selection.Insert(container); } } } private void Button_Click_1(object sender, RoutedEventArgs e) { // this doesn't have the markup from the inserted image System.Windows.MessageBox.Show(richTextBox3.Xaml); } What is the correct way to insert an image into the RichTextBox at runtime so that it can be persisted to a data store?

  • WPF binding not updating until after another action

    - by Matthew Stanford
    I have an observable collection bound to a listbox in WPF. One of the options in the window is to use an OpenFileDialog to add an item to the listbox with certain properties. When I use the OpenFileDialog it immeditaely sets two of the properties of the new item in the observable collection. I am using INotifyPropertyChanged to update the listbox. These two new properties are set correctly and now the listbox should display the title contained in the new title property and the title textbox which is bound to the listbox should display the new title as well. However, neither displays the new title upon the closing of the OpenFileDialog and when I click on another item in the listbox and come back to the item I have just changed it updates the title textbox but the title displayed in the list box is not changed until i move the item in the list box that I want to change. Here is the Binding code. ItemsSource="{Binding Path=MyData, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" And here is the implementation of the browse button that is not working (L1 being the listbox) private void browse_Click(object sender, RoutedEventArgs e) { OpenFileDialog opf = new OpenFileDialog(); opf.ShowDialog(); MyData[L1.SelectedIndex].Title = System.IO.Path.GetFileNameWithoutExtension(opf.FileName); MyData[L1.SelectedIndex].Command = opf.FileName; } When I simply type in the text boxes and click out of them it updates the list box immediately with the new information I have put in. I also have a create new button and upon clicking it, it immediately adds a new item to the list box and updates its' properties. The only one that is not updating correctly is this peice of code I have given you. Thanks for your help. EDIT: Here is my implementation of INotifyPropertyChanged private OCLB _MyData; public OCLB MyData { get { return _MyData; } set { _MyData= value; FirePropertyNotifyChanged("MyData"); } } OCLB is the obserable collection. Here is the function FirePropertyNotifyChanged public event PropertyChangedEventHandler PropertyChanged; private void FirePropertyNotifyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } Each of these are in the partial class MainWindow for the wpf form. I also have a class for the MyData files (with 4 get/set functions) that are stored in the OCLB(observable collection). There is also a class with functions for the OCLB.

  • Static initializer in Java

    - by Szere Dyeri
    My question is about one particular usage of static keyword. It is possible to use static keyword to cover a code block within a class which does not belong to any function. For example following code compiles: public class Test { private static final int a; static { a = 5; doSomething(a); } private static int doSomething(int x) { return (x+5); } } If you remove the static keyword it complains because the variable a is final. However it is possible to remove both final and static keywords and make it compile. It is confusing for me in both ways. How am I supposed to have a code section that does not belong to any method? How is it possible to invoke it? In general, what is the purpose of this usage? Or better, where can I find documentation about this?

  • WinForms Form won't close on pressing X or Close() in C#

    - by MadBoy
    I'm having a bit weird problem with WinForm which seems to refuse to close for some weird reason. I've got very simple gui which sometimes doesn't react for me pressing X or when i use events on buttons it even reaches Close() and does nothing.. private void buttonZapisz_Click(object sender, EventArgs e) { string plik = textBoxDokumentDoZaladowania.Text; if (File.Exists(plik)) { string extension = Path.GetExtension(plik); string nazwaPliku = Path.GetFileName(plik); SqlMethods.databaseFilePut(plik, comboBoxTypDokumentu.Text, textBoxKomentarz.Text, sKlienciID, sPortfelID, extension, nazwaPliku); Close(); } } There are no events assigned to FormClosed or FormClosing. So how can I find out what's wrong. Sometimes X will work after the GUI is loaded but after i press Button to save some stuff to database it reaches Close() in that button event and it still is visible and does nothing. Can't use X, nor ALT+F4. I can go around GUI and choose other values for ComboBox without problem. I call GUI like this: private void contextMenuDokumentyDodaj_Click(object sender, EventArgs e) { var lv = (ListView) contextMenuDokumenty.SourceControl; string varPortfelID = Locale.ustalDaneListViewKolumny(listViewNumeryUmow, 0); string varKlienciID = Locale.ustalDaneListViewKolumny(listViewKlienci, 0); if (lv == listViewDokumentyPerKlient) { if (varKlienciID != "") { var dokumenty = new DocumentsGui(varKlienciID); dokumenty.Show(); dokumenty.FormClosed += varDocumentsGuiKlienci_FormClosed; } } else if (lv == listViewDokumentyPerPortfel) { if (varPortfelID != "" && varKlienciID != "") { var dokumenty = new DocumentsGui(varKlienciID, varPortfelID); dokumenty.Show(); dokumenty.FormClosed += varDocumentsGuiPortfele_FormClosed; } } } While I can't close GUI i can work on the main gui without problem too. I can open up same GUI and after opening new GUI i can quickly close it. GUI is very simple with few ComboBoxes,TextBoxes and one EditButton from Devexpress. Edit: varDocumentsGuiPortfele_FormClosed code allows me to refresh GUI (reload ListView's depending on where the user is on now). private void varDocumentsGuiPortfele_FormClosed(object sender, FormClosedEventArgs e) { TabControl varTabControl = tabControlKlientPortfele; if (varTabControl.TabPages.IndexOf(tabPageDokumentyPerKlient) == varTabControl.SelectedIndex) { loadTabControlKlientPortfeleBezZmianyUmowy(); } }

  • LLBLGenProDataSource : cannot see updates values of newly inserted item from a FormView

    After performing a FormView.InsertItem, I am unable to read the new values from the bound object within the LLBLGenProDataSource that the FormView is bound to. I have tracing turned on, I can see the insert happen, and the data does make it into the database, yet when I examine the contents of LLBLGenProDataSource.EntityCollection(0) (there is only one item in the collection) I do not see the values from the FormView.....yet, they are somehow being inserted into the database.

  • Building a virtualized SPARC environment

    - by Owen Allen
    If you're interested in making effective use of virtualization tools like Oracle VM Server, there's a whitepaper on oracle.com that you should check out. The whitepaper starts with a few specific technologies and hardware: Oracle VM Server for SPARC, T4 Servers, Ops Center, Solaris 11, Sun Network 10GbE Switches, and Sun ZFS Storage Appliances. It then explains how to use them to plan and set up a virtualized environment, in which guests are grouped in Server Pools with high availability and are managed through Ops Center. It explains how Ops Center simplifies the management of logical domains by using custom plans to create new logical domains and managing their life cycle through its user interface. So, if you're interested in setting up a cloud and you want to avoid surprises along the way, have a look.

  • Why do I get Detached Entity exception when upgrading Spring Boot 1.1.4 to 1.1.5

    - by mmeany
    On updating Spring Boot from 1.1.4 to 1.1.5 a simple web application started generating detached entity exceptions. Specifically, a post authentication inteceptor that bumped number of visits was causing the problem. A quick check of loaded dependencies showed that Spring Data has been updated from 1.6.1 to 1.6.2 and a further check of the change log shows a couple of issues relating to optimistic locking, version fields and JPA issues that have been fixed. Well I am using a version field and it starts out as Null following recommendation to not set in the specification. I have produced a very simple test scenario where I get detached entity exceptions if the version field starts as null or zero. If I create an entity with version 1 however then I do not get these exceptions. Is this expected behaviour or is there still something amiss? Below is the test scenario I have for this condition. In the scenario the service layer that has been annotated @Transactional. Each test case makes multiple calls to the service layer - the tests are working with detached entities as this is the scenario I am working with in the full blown application. The test case comprises four tests: Test 1 - versionNullCausesAnExceptionOnUpdate() In this test the version field in the detached object is Null. This is how I would usually create the object prior to passing to the service. This test fails with a Detached Entity exception. I would have expected this test to pass. If there is a flaw in the test then the rest of the scenario is probably moot. Test 2 - versionZeroCausesExceptionOnUpdate() In this test I have set the version to value Long(0L). This is an edge case test and included because I found reference to Zero values being used for version field in the Spring Data change log. This test fails with a Detached Entity exception. Of interest simply because the following two tests pass leaving this as an anomaly. Test 3 - versionOneDoesNotCausesExceptionOnUpdate() In this test the version field is set to value Long(1L). Not something I would usually do, but considering the notes in the Spring Data change log I decided to give it a go. This test passes. Would not usually set the version field, but this looks like a work-around until I figure out why the first test is failing. Test 4 - versionOneDoesNotCausesExceptionWithMultipleUpdates() Encouraged by the result of test 3 I pushed the scenario a step further and perform multiple updates on the entity that started life with a version of Long(1L). This test passes. Reinforcement that this may be a useable work-around. The entity: package com.mvmlabs.domain; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; import javax.persistence.Version; @Entity @Table(name="user_details") public class User { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; @Version private Long version; @Column(nullable = false, unique = true) private String username; @Column(nullable = false) private Integer numberOfVisits; public Long getId() { return id; } public void setId(Long id) { this.id = id;

The last two tests pass as expected. Now change Spring Boot version to 1.1.4 and rerun, all tests pass. Are my expectations wrong?
