JSF :: Primefaces - Two Messages Getting Displayed Instead Of One For Ajax Blur Event
Jan 28, 2014
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.
JSF page
<h:form id="lpcForm">
<div id="content">
<p:commandLink id="cmdLinkDelete" value="Delete"
style="font-size:15px;padding-left:15px;" ajax="true"
action="#{lpcBean.deleteRecords}" update=":lpcForm:lpcDataTable" />
[Code] ....
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.

I have a problem to display a popup with the information of the registered event. I would like the user to hover over a particular event exhibited only the description of the event without having to click on the event to view information. I would like to make an ajax request to that was displayed a popup.
But do not know how to implement jquery and javascript. Well, I am new to programming. My code that generates the schedule is as follows:
<p: schedule value = "#{bean.datamodel}" widgetVar = "sheldule" locale = "en"
rightHeaderTemplate = "prev, next" leftHeaderTemplate = "today" centerTemplate = "month"
id = "events"
tooltip = "true">
<p:ajax event="dateSelect" listener="#{bean.onDateSelect}" update="eventsNew" oncomplete="eventDialog.show();"/>
<p:ajax event="eventSelect" listener="#{bean.onEventSelect}" update="eventsNew" oncomplete="eventDialog.show()"/>
</ p: schedule>
In my Bean have methods that make the selection of date and event. Have I configured the option of setEditable to true. Ajax function, jquery or javascript to show the popup containing only observation and event date. And looked at the documentation of primefaces and not found any implementation to solve my problem.

I have a small problem with my code that I can't figure out how to make it work the way it is supposed to. The code is supposed to be a game where a user has to guess numbers between 1-1000. The program counts how many times the user tried to guess the number and it displays a certain message if the guess number is less than 10, more than 10 or 10. I was able to write the code using loops. However, the messages will not always get printed on to the screen. The code seems to work fine except for the last part where the messages, "Either you know the secret or you got lucky", "You should be able to do better", "Aha! you know the secret!" are not always displayed like they are supposed to.
import java.util.Scanner;
public class Guess1 {
public static void main(String[] args) {
int secretNumber;
secretNumber = (int) (Math.random() * 999 + 1);
Scanner input = new Scanner(System.in);
int guess;
int replay;
int test;
test=1;
replay=1;
int count=0;
[code]....

I have the following code that comes directly from the book Core Java vol 1. The last two statements are mine but when I change the last statement's String the message being logged doesn't change. For that manner when I change the level of the last statement the file doesn't update to the correct log level. What am I doing wrong?
Java Code:
public class LogTester
{
public static void main(String[] args)
{
if (System.getProperty("java.util.logging.config.class") == null
&& System.getProperty("java.util.config.file") == null)
[code]....
Forgot to say the file also only logs the old message and level from a previous recompilation

I am new to Java/OOP in general, and am trying to implement a multi-threaded system that contains a master thread, and a set of worker threads that are heterogeneous in the work they do. Once they complete the work, the workers indicate to the master by posting the result on to its queue. Here is the problem. The results of each type of work is different, and the master has to process each differently. In C (which I'm familiar with), this can be achieved by having a message type that is a union of all the expected messages, and by using a switch statement.
I thought of doing something similar in Java, by using instance of on each incoming message (each individual message class having been subclassed from a super message class) , and doing switch on that, but it doesn't seem to be the OO way to do things. The only other way I could think of was to implement an abstract method to get the type of each message, and then use the type in a switch statement, or if-then-else. Is there some other Java idiom to do this kind of processing? Also, if this is an acceptable method, why is it superior to using the reflection to find out the message type (instead of using the abstract getType())?
The message types look similar to the code below:
abstract class Message {
abstract String getType();
} class Result1 extends Message {
ResultType1 content;
String getType() {

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 using standard JSF 2.1.
<div style="font-family: Verdana; font-size: 10pt; color: #FFFFFF">
<h2>Calibrations</h2>
<h:form id="tunerSelectionForm" style="color: #000000">
<h:commandLink>

I am attempting to maintain separate files for different types of "messages" (user messages, field labels/buttons, data values). In this attempt I am trying to get the description of different data values. For example, a UserStatus "A" might be displayed as Active or Activo.
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="defaultEncoding" value="UTF-8"/>
<property name="basenames">
<list>
<value>WEB-INF/locale/messages/messages</value>
<value>WEB-INF/locale/fields/fields</value>
<value>WEB-INF/locale/values/values</value>
</list>
</property>
</bean>
Here are the relevant entries in the values_en_us.properties file:
user.status.A = Active
user.status.I = Inactive
user.status.P = Pending
I would like to build an Enum for each type of value that I can get the localized value from. In the code below, I have hardcoded the values being passed to the get message to reduce the number of variables when trying to debug this.
import java.util.EnumMap;
import java.util.HashMap;
import java.util.Locale;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public enum UserStatusEnum {
[Code] ....
When this code runs, I get the following message:
org.springframework.context.NoSuchMessageException: No message found under code 'user.status.A' for locale 'en_us'.
On this line of code:
description = appCtx.getMessage("user.status.A", null, new Locale("en_us"));
The application is already showing my custom application error messages I have in the messages localized files, but in that case the ApplicationContext is already available. Because I can get to the contents of the messages_en_us.property files, I'm assuming me config is correct. However, the classes that get the messages content are instantiated by Spring.
The Enums are not created by Spring, so my assumption is that I am doing something wrong in how I am getting a handle on the ApplicationContext or how I am using it.
After looking at the appCtx values in debug mode, I can see that the messageSource > basenames does at least contain my configuration data.
[WEB-INF/locale/messages/messages, WEB-INF/locale/fields/fields, WEB-INF/locale/values/values]
Although I don't see the whole filenames with the file extension anywhere or the property file entries.

I'm working on a project that has two separate components. The first is a back end, that will do most of the heavy lifting, the other part is a front end GUI. The GUI will include the back end into it's project as an imported JAR file.
I need to be able to keep these two decoupled, as I might be writing different front ends using the same back end. The challenge in front of me (well one of many) is how to pass messages from the back end to the GUI so I can report things that are happening.
For example, if i call method FOO, FOO might do several different things; connect to a database, divide by zero, solve world hunger. I want to be able to either tie a JTextArea , or another component (or multiple components) to this stack of information, or at the very least, have something listening for this information, and when I see that my back end reports something, my front end is quickly aware of this information, and then I can process it and inform the user of the front end.
It would also be useful to be able to send a message from front end to back end , so perhaps the back end might learn that the front end user is unhappy and would like to stop running the current query.

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:
<h:form>
<h:commandButton value="#{text.update }">
<f:ajax execute="@form" render="@form" listener="#{backing.update}" />
</h:commandButton>
</h:form>
Calling the UICommand object (which represents the pressed button) getActionExpression method returns NULL.

When I look at all the showcase from various "faces" components, I see lots of Javascript, powered by jQuery, etc.
Where's the Java part of things? Are JSF component simply JavaScript Ajax widgets?
What makes a JSF component different than say a regular old webpage using jQuery to do something in Ajax to a PHP back end script?

I have a simple method in Java through which I send commands to a machine over TCP. The problem is:
Machine can't accept more than two connections in 20 seconds.
I need to send 15-20 commands to the machine in 3 minutes.
This is my current method which is not working as it should, 2 commands get transmited but third command hangs because of the machine.
void sendCommand(String command) throws IOException {
String ipaddress = "192.168.0.2";
Socket commandSocket = null;
BufferedWriter out = null;
BufferedReader in = null;
BufferedWriter outToDetailFile = null;
[Code] .....
Basically what i need is:
1st: I need to open the connection by calling method
public void openConnection(String ipaddress, String port){
//Code to start the connection
}
2nd: I need to be able to send commands to the connection I have already opened (i will send multiple messages in time period of 5-10 minutes):
public void sendCommand(String message){
}
3rd: Close that connection
public void closeConnection(){
}

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 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 am writing this program for my Java level 1 class. I am able to get it to compile and run, however nothing is outputted. Below are the instructions and the code that I have written.
Instructions:
Write an application that calculates and displays the amount of money a user would have if his or her money could be invested at 5 percent interest for one year. Create a method that prompts the user for the starting value of the investment and returns it to the calling program. Call a separate method to do the calculation, and return the result to be displayed.
Below is the code that I have written
import java.util.Scanner;
public class Interest

//main method
public static void main(String[] args)
{
originalAmount();
