I have two images. I want to be able to click them and kick off a call to a listener in Java to change a value in the bean. I also want the view to update my dropdown (labeled "menuModel") to either be rendered or not, depending on which image I click. Alternatively, I would be fine with the dropdown simply being disabled and enabled for the same criteria.
So far, the listener kicks off fine, and the value gets updated correctly in the bean. However, the view never gets updated. I have tried this a hundred different ways, but nothing seems to work. If I hit refresh on my browser, the view updates. But I want it to do it automatically.
I am building a room management system in Java (Netbeans) and Ms Access. The jasper report is only showing code (source view) instead of design view. The GUI JFrame and Login JFrame are not displaying records in the database and the buttons are not working. Also the labels and text fields are not neatly arranged. The connection to the database is not displaying records.
Connection to the database. COIRMS.java
package Login; import java.sql.*; public class COIRMS { Connection con; Statement st; ResultSet rs; public COIRMS ()
I have a requirement where a form is present with first name, last name, file upload etc. File upload is done through ajax call and then the form is submitted to a servlet. I want to know whether the file has been uploaded or not in the servlet which is called after i click on the form submit button. So is there any way i can read the response of the ajax call in the servlet ?
I'm having problems with using the h:inputFile tag with JSF 2.2 and Glassfish 4.0 on Eclipse. The file uploads work when the enctype is set to "multipart/form-data" in the h:form tag, but AJAX will not work. When I leave out the encType (defaults to "application/x-www-form-urlencoded") AJAX works but the uploads do not work, and in fact Glassfish crashes and generates the message:
The request content-type is not a multipart/form-data
Likewise I'm having the same problems with the PrimeFaces file upload tag p:fileUpload. In a JSF 2.0 it works correctly, but with JSF 2.2 it's giving the same problems and generates the message above.
When I start up Eclipse it tells me that Mojarra 2.2.0 is installed. Is this the source of the problem, and if so, how do I install a later version of Mojarra?
I'm required to implement audit logging of all action requests. The logging should contain the action name and request parameters. I have implemented the logging in a phase listener (PhaseId.INVOKE_APPLICATION).
I'm having trouble figuring out how to get the action name from ajax requests. More specific when the form command button does not contain an action attribute:
I am getting the problem as If call the action class through the ajax, my property values not setting to the formbean class, How can I use the formbean to set the all my property values and getting in action class.
I have a page which lists items using a ui:repeat. The repeat is surrounded by my h:form tag.
Now I have made it so that when click an item, then I load some item details - render them in their own xhtml file and inject the result into the dom tree.
This is causing some problems.
* My injected content has commandButtons and commandLinks which do not work because I don't have a form in my injected page - since this would cause nested forms :-( * tried to replace commandButtons and commandLinks and instead create unique url's that I can call to get my work done - but how to I then re-render a panelGroup on then page? tried using jsf.ajax.request but I'm not able to get part of the page (a shoppingcart) to update
Basic outline
<h:form> <table> <ui:repeat ...> <tr><td onclick="...">Click here to load item details</td></tr><tr><td id="itemDetailPlaceholder"></td></tr> </ui:repeat> </table> </h:form>
I'm trying to pass the form parameters from one JSP. to other using AJAX but my output JSP is only showing [object HTMLInputElement] [object HTMLInputElement] error. Im new ajax.

I am new to JSF and I am working on handling session timeout for a JSF application. I am trying to get the code to work for ajax calls and not able to achieve that so far. I have tried two approaches:
Approach 1: SessionListener (for cleanup work) and SessionFilter (for filtering every request and checking if session timed out)
My Code snippet of doFilter() of SessionFilter:
if ((request instanceof HttpServletRequest) && (response instanceof HttpServletResponse)) { HttpServletRequest httpServletRequest = (HttpServletRequest) request; HttpServletResponse httpServletResponse = (HttpServletResponse) response; // is session expire control required for this request? (not required for home page or timeout page or JSF resources) if (isSessionControlRequired(httpServletRequest)) {
[Code] .....
Both these approaches work for non-ajax POST calls but not for ajax calls. When I run my app in debug mode, I can step through all the statements for ajax calls also, which gives me an idea that the control does come to my code, executes it but for some reason, nothing happens on the UI.
I have been trying to redirect user to a timeout page but the ideal thing would be to display a JSF dialog and upon hitting 'OK' take user to Home Screen (My app does not have a login screen.) I have a basic questions also, is view expiring exactly same as session timeout?
I have one row editable datatable.I have implemented email validation to one of the column where error message must display on blur of email field.This is working fine.I have a dialog with form to be displayed in the same page. Validation is implemented to this form also with on blur event. The dialog validation message gets displayed on blur but along with that the main form also displays the same validation message. This should not happen.
The message with id lpcErrMsg is the one that i am displaying on blur in the main page when email format is wrong.And this message gets displayed with dialog field validation also although i have never referred to this id to be rendered in the dialog.
The message with id lpcDlgMsg is the message that i am displaying inside the dialog with widgetvar dlg on blur.As of now i have implemented blur event validation for the first required field in the dialog.
If user register himself and will go to his own profile then he will be asked upload profile photo at that time when he uploads his photo dynamically... for this I have to insert imageurl/imagepath into table (mysql) using jquery/ajax and image to respective folder depends on userID?
I'd like to disable/enable SelectManyCheckbox and the SelectOneMenu based on my selection. I have two radio buttons to be selected whether A or B. The SelectManyCheckbox and the SelectOneMenu should be disabled at the first run. When the user selects “A” the SelectManyCheckbox and the SelectOneMenu should be enabled and if the users selects “B”, the SelectManyCheckbox and the SelectOneMenu should be disabled and the items should be empty. I tried to use <f:ajax render="certificates"/>, but it doesn't work properly.
I am using JSF2 with Primefaces. Here is my business requirement-Hidden field on JSF page should take the value from the session object that is set in managed bean. Session object is updated every time when the user submits the page. I am able to update the session object in the managed bean and able to get the value in the hidden field first time and after that i see the same value in the hidden field even though session object has different value. Here is the hidden field: <h:inputHidden id="xyz" value="xyz"/> i tried using sessionScope but still didn't work.
I have a jTextPane set up and a panel with radioButtons. My jTextPane displays the contents of a text file I have chosen. The 3rd line, 4th index, displayed in my jTextPane specifies a value of type int. When I click my radioButton, I would like that value to increase by 1. So far, I have the following code. I tried to pane.setText(value + 1), but that doesn't seem to work. How do I update the value and display the updated value in jTextPane?
My code :
private final ActionListener actionListen = new ActionListener() { for(String line: pane.getText().split("")){ String lineThree = line[3]; int value = lineThree.charAt(4); if(radioButton.isSelected()){ pane.setText(value+1); } }};
Is it possible to map URL's with independent view dir structure? If so how?
My goal is to simply point an url to a specific view file:
i.e.
[URL] ....
to not/default/path/views/main/index.xhtml and www.myserver.com/application/admin/ to not/default/path/views/admin/index.xhtml
A couple solutions I found so far where:
Solution 1
PrettyFaces
I just didn't wanted to use a third party solution. This is my best solution so far.
Solution 2(a JSF solution):
navigation rule entries in the faces-config.xml file.
A bean is required, not a bad thing in above example but not great in combination with static navigation like:<h:commandButton action="index"/>
Solution 3 (another JSF solution)
Resource Library Contracts This forces me to work in the contracts file.
None of the solutions gave me a clear solution except prettyfaces.
Are there some elegant native JSF solutions ? Something flexible and reusable? Something like a mvc controller i used to use in php applications. In this controller I was able to add a template file in the constructor and an content file in specific function. Custom paths where no problem. I didn't want to use mvc nor the php language in this project.
The program runs well , it adds the applet but it dosn't update the interface unless I press "_"(Minimize) . To be more clear , the object paints a spring wich goes through 4 stages , it is added to the JFrame but it dosn't uptade until I minimize the frame , that is when it goes to the next stage .
The main class which calls the spring to be added to the frame :
public class principal implements ActionListener ,Runnable{ JTextField field; JFrame frame; private class Action implements ActionListener { public void actionPerformed(ActionEvent event) { frame.repaint();
I am trying to Make A GUI which has a Jcombo box i also want it to have a jlabel that up dates depending on which option the user selects from the JcomboBox
for exampl if i select lion i want it to say you chose lion on the Jlabel and if i choose ostrich i want it to say ostrich and so on
I have loaded the combo box at starting of program.When i am adding the element to combo box through database it's not updating visually.But the inserted data is successfully loaded in List.
When I add an element to my array, I have to make sure that it stays a heap, ie every child is smaller than its parent. However the method that I am using for this, trickling up, is not updating the elements properly, it pretty much just leaves is as is.
Here is the relevant code:
public class MaxIntHeap { int[] array; int actualSize = 0; public MaxIntHeap(){ array = new int[20];
Why the Progress Bar is not Working in Second attempt?When i am Invoking Below Method on actionPerformed at first attempt its Working Fine but After that Its Not Working at all....
My program is working fine. When I executes it, it shows me this:
The clock is 54 minutes over 23 (+41 seconds.
and when i press ENTER, it shows me this:
23:54:41
But then it won't show me the update. I want to update the time, for example when I started the execution the time was 23:54:41 but it must show me something like 23:54:45, because I need the current time.
I have searched the whole internet about this but I don't know how to use the "Date.update ();".
Here is my code
package p2;
import java.util.Calendar; import java.util.Date; import javax.swing.JOptionPane; public class Time { public void myTime() { Calendar cal = Calendar.getInstance();
create an application following the MVC pattern. My frame is composed of a JTable with some JComboBox and classic next/previous buttons to page the table. The table shows data of current accounts of the members of a family. My problem is figuring out how the controller interacts with the view, for example to enable / disable buttons or reset and reload the data in the comboboxes. In the view class all the graphical components are private instance variables. What is the best approach to ensure that the controller can act on them?
I need to create in the view public methods to act on each component like getSelectedItemAccountCombo, getSelectedItemYearsCombo, getSelectedItemMonthCombo, populateAccountCombo (ArrayList <String> list), setNextButton (boolean b) ... and so on (I think that the methods would be many ...) This approach does not convince me because I think that the class is fouled by procedures that should be in the controller class.
