I am trying to implement prime push counter in my project. I am using PrimeFaces3.5, Jboss7.0 and Eclipse Indigo version.
I have added jars related to prime push:
atmosphere-annotations-1.0.1.jar
atmosphere-compat-jbossweb-1.0.1.jar
atmosphere-compat-tomcat-1.0.1.jar
atmosphere-compat-tomcat7-1.0.1.jar
atmosphere-runtime-1.0.1.jar
primefaces-3.5.jar and jsf and slf4j jars
My xhtml code:

My managed bean:
#ManagedBean(name = "pushBean")
#ApplicationScoped
public class PushBean {
public PushBean() {
}
private int count;
public int getCount() {
return this.count;
}
public void setCount(final int count) {
this.count = count;
}
public synchronized void increment() {
this.count++;
PushContext pushContext = PushContextFactory.getDefault().getPushContext();
pushContext.push("/counter", String.valueOf(this.count));
}
}
When I click the button in UI, the count is incremented on the server, but it is not reflected in UI automatically, because it is not updated. But when I refresh the page, the count is incremented as expected.
Exception I am getting is:
13:00:02,298 ERROR [stderr] (http--0.0.0.0-8080-5) [http--0.0.0.0-8080-5] ERROR org.atmosphere.cpr.AtmosphereFramework - AtmosphereFramework exception

This exception happens when your web app is run in Servlet 3 compliant containers. The correct web.xml must have the async-supported element set to true, for example:
<servlet>
<servlet-name>Push Servlet</servlet-name>
<servlet-class>org.primefaces.push.PushServlet</servlet-class>
<async-supported>true</async-supported>
</servlet>
Reference: Installing Atmosphere
I'm not very sure about push framework but i think the problem is with your javascript.
you are trying to refresh ".display" control but there is nothing like .display.
Try '.out' instead of .display

i have a simple file.xhtml in a JSF2.2 application, that's its code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<html xmlns="http://www.w3.org/1999/xhtml"

<body>
<f:view>
<h:form id="greeting">
<h:inputText id="num1" value="#{jSFeatBean.num1}" />
<h:inputText id="num2" value="#{jSFeatBean.num2}"/>
<h:commandButton type="submit"
value="Submit"
action="#{jSFeatBean.addNumbers()}"/>
<h:outputText value="#{jSFeatBean.result}"/>!
</h:form>
</f:view>
</body>
</html>
and this is my #ManagedBean:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
#ManagedBean(name = "jSFeatBean", eager = true)
#SessionScoped
public class JSFeatursBean {
private String result;
public int num1 = 1;
int num2;
public int getNum1() {
return num1;
}
public void setNum1(int num1) {
this.num1 = num1;
}
public int getNum2() {
return num2;
}
public void setNum2(int num2) {
this.num2 = num2;
}
public String getResult() {
return result;
}
public void setResult(String result) {
this.result = result;
}
public Object addNumbers() {
setResult("il risultato e': "+ Integer.toString(num1+num2));
return null;
}
}
after i start jboss from Eclipse the browser display all elements of my file.xhtml properly but the values in the first (id = num1) inputText is 0 and not 1. Why this happens? If i put new values in the inputText boxes everything works fine, so i think that the Mbean is instantiated and working.
I have the same problem with a h:SelectOneListbox element, that doesn't show the list i create when i call the MBean constructor.
It looks like the MBean gets instatiated right after the display of html page.
The code looks fine to me with just one thing that might cause the problem.
Try remove "eager = true" attribute in your ManagedBean annotation. "eager = true" only works with ApplicationScoped Beans.
I am trying to learn Struts2, I have used a view page that hits action , the action class is using a bean where getter setter methods are written and the action is also using a dao where the connection is written.I want to mention that I am using jboss v5.0 and eclipse, I have added all the jar files.
Now , when I am trying to run this application the welcome jsp page is hitting properly then on clicking submit button the below error is showing:
There is no Action mapped for namespace /controller and action name
I am placing my code and directory structure. I have tried the using namespace="/"
<result name="SUCCESS">/success.jsp</result>, still its is not working

This error
There is no Action mapped for namespace /controller and action name
generally means Struts can't find the action specified in a namespace specified (/controller in this case). BTW in your case you've not specified /controller anywhere and the action name is missing in the error message, so this error could be probably generated by the bunch of other errors you have in your action / JSP / configuration.
you also have two typos, preventing anything to work:
sturts-default instead of struts-default:
<package name="default" extends="struts-default">
"SUCCESS" instead of "success", that is the result mapped to the constant SUCCESS that you are returning from the Action method.
<result name="success">/success.jsp</result>
If using Struts version newer than or equals to 2.1.3, you need the new filter, StrutsPrepareAndExecuteFilter instead of the deprecated FilterDispatcher;
The action method must be a public String something() with no parameters. This:
public String execute(HttpServletRequest request , HttpServletResponse response) throws Exception
is simply wrong, and should be:
public String execute(){}
Here
String Name = request.getParameter("Name");
String Age = request.getParameter("Age");
String Location = request.getParameter("Location");
TestBean bean = new TestBean();
bean.setName(Name);
bean.setAge(Age);
bean.setLocation(Location);
you are reinventing the wheel really badly. Attributes must be private, at class level, with getters and setters, and they'll be populated automatically, with no need to access the request. In your case:
private TestBean bean;
/* GETTER AND SETTER */
public String execute(){
System.out.println(bean.getName());
// ...
}
Unrelated, but Java naming conventions use lower-case names for local variables and instance properties.
In JSP page, you need to access the getter with a starting lowercase character:
<s:textfield name="Name" label="Name"/>
must be
<s:textfield name="name" label="Name"/>
and so the other fields. Also if you point to an object like TestBean, you need to do like this:
<s:textfield name="bean.name" label="Name"/>
This are the main problems... BTW consider start coding after having read a book, or some good tutorial. Starting in the dark like this is not the right way, IMHO.
Following are points which you should notice,
If you are using TestBean class as data carrier, you have to implement ModelDriven Interface.
TestAction.java should present in "Controller" package.
If you want HttpServletRequest and HttpServletResponse in your execute() method, then the simplest way you can get that is to implement ServletRequestAware and ServletResponseAware interfaces and implement respective methods.
And most important if your success.jsp is in Web Content folder, then you dont need to specify
<result name="SUCCESS">/success.jsp</result>
Just make it like
<result name="SUCCESS">success.jsp</result>
And if you have any folder suppose, "Folder1" in Web Content, Then specify like
<result name="SUCCESS">Folder1/success.jsp</result>
I'm new to jsf technology and I'm trying to understand when and how the ViewScoped jsf bean is initialized.
I have a sample app with 2 beans
ApplicationScopedBean.java
#ManagedBean
#ApplicationScoped
public class ApplicationScopedBean implements Serializable {
private int incrementedCounter =0;
public int getIncrementedCounter() {
incrementedCounter += 1;
return incrementedCounter;
}
}
ViewScopedBean.java
#ManagedBean
#ViewScoped
public class ViewScopedBean implements Serializable {
#ManagedProperty(value = "#{applicationScopedBean}")
private ApplicationScopedBean applicationScopedBean;
private int reincarnationNumber;
private int accessCounter;
#PostConstruct
public void initialize() {
accessCounter = 0;
reincarnationNumber = applicationScopedBean.getIncrementedCounter();
System.out.println("Initializing viewScoped stateManager with reincarnationNumber value = " + String.valueOf(reincarnationNumber));
}
public void noAction() {
//do nothing
}
public int getReincarnationNumber() {
return reincarnationNumber;
}
public int getAccessCounter() {
accessCounter += 1;
return accessCounter;
}
public ApplicationScopedBean getApplicationScopedBean() {
return applicationScopedBean;
}
public void setApplicationScopedBean(ApplicationScopedBean applicationScopedBean) {
this.applicationScopedBean = applicationScopedBean;
}
}
ApplicationScoped bean is created only once for the application launch.
Every time ViewScoped bean is being created, the reincarnationNumber is being increased by 1.
I also have a simple jsf page to display these values:
index.xhtml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>View Scoped bean test</title>
</h:head>
<h:body>
<h:form>
<p>ViewScoped bean reincarnation is <h:outputText value="#{viewScopedBean.reincarnationNumber}"/></p>
<p>ViewScoped bean access counter is <h:outputText value="#{viewScopedBean.accessCounter}"/></p>
<h:commandButton type="submit" value="no action" action="#{viewScopedBean.noAction()}"/>
<h:commandButton type="submit" value="reload this page" action="index"/>
</h:form>
</h:body>
</html>
The problem:
When I launch the application the first time, I already have reincarnationNumber value equal to 3.
In other words, I have this info displayed in browser:
ViewScoped bean reincarnation is 3
ViewScoped bean access counter is 1
Why is that?
Why ViewScoped bean has bean created 3 times?
Thanks in advance!
SOLUTION
As it is stated in the comments, the cause was "start browser" checkbox checked in Run Configurations in my IntelliJ IDEA. The trick is when browser is auto-started from IDE I have viewScopedBean initialized 3 times.
It's not created 3 times, just called the getter several times... and that's because... you can check this answer:
Why JSF calls getters multiple times
I put this problem in a simple example, a composite component that calculates the sum of 2 inputs and prints the result in an outputText
Main JSF page:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ez="http://java.sun.com/jsf/composite/ezcomp/">
<h:head></h:head>
<h:body>
<ez:Calculator />
<br/>
<br/>
<ez:Calculator />
<br/>
<br/>
<ez:Calculator />
</h:body>
</html>
Composite component XHTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:composite="http://java.sun.com/jsf/composite"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>This content will not be displayed</title>
</h:head>
<h:body>
<composite:interface componentType="calculator">
</composite:interface>
<composite:implementation>
<h:form>
<h:inputText id="first" value="#{cc.firstNumber}" />
<h:commandButton value="+" action="#{cc.sum}"/>
<h:inputText id="second" value="#{cc.secondNumber}" />
</h:form>
<h:outputText id="result" value="#{cc.result}" />
</composite:implementation>
</h:body>
</html>
Composite component backing bean:
package ez;
import javax.faces.component.FacesComponent;
import javax.faces.component.UINamingContainer;
#FacesComponent("calculator")
public class Calculator extends UINamingContainer {
private Long firstNumber;
private Long secondNumber;
private Long result;
public Calculator() {
}
#Override
public String getFamily() {
return "javax.faces.NamingContainer";
}
public void setFirstNumber(String firstNumber) {
this.firstNumber = Long.parseLong(firstNumber);
}
public String getFirstNumber() {
if(firstNumber == null) {
return null;
}
return firstNumber.toString();
}
public void setSecondNumber(String secondNumber) {
this.secondNumber = Long.parseLong(secondNumber);
}
public String getSecondNumber() {
if(secondNumber == null) {
return null;
}
return secondNumber.toString();
}
public String getResult() {
if(result == null) {
return null;
}
return result.toString();
}
public void setResult(String result) {
this.result = Long.parseLong(result);
}
public void sum() {
this.result = this.firstNumber + this.secondNumber;
}
}
So, I have 3 Composite Components that all should do the same thing, but when I press a SUM button, after the server processes the request, the result is printed out on the page, but the other 2 components are cleared of their values.
How can I prevent this? How can I force it to retain those values?
UIComponent instances are recreated on every request, hereby losing all instance variables everytime. They basically act like request scoped managed beans, while you intend to have them in the view scope. You need to take view state saving into account on a per-attribute basis. This is normally by default already done for all attributes of #{cc.attrs}. So, if you can, just make use of it:
<cc:interface componentType="calculator">
<cc:attribute name="firstNumber" type="java.lang.Long" />
<cc:attribute name="secondNumber" type="java.lang.Long" />
</cc:interface>
<cc:implementation>
<h:form>
<h:inputText id="first" value="#{cc.attrs.firstNumber}" />
<h:commandButton value="+" action="#{cc.sum}"/>
<h:inputText id="second" value="#{cc.attrs.secondNumber}" />
</h:form>
<h:outputText id="result" value="#{cc.attrs.result}" />
</cc:implementation>
with just this (nullchecks omitted; I recommend to make use of required="true" on the inputs)
#FacesComponent("calculator")
public class Calculator extends UINamingContainer {
public void sum() {
Long firstNumber = (Long) getAttributes().get("firstNumber");
Long secondNumber = (Long) getAttributes().get("secondNumber");
getAttributes().put("result", firstNumber + secondNumber);
}
}
Otherwise, you'd have to take state saving into account yourself by delegating all attribute getters/setters to UIComponent#getStateHelper(). Based on the very same Facelets code as you have, the entire backing component would look like this:
#FacesComponent("calculator")
public class Calculator extends UINamingContainer {
public void sum() {
setResult(getFirstNumber() + getSecondNumber());
}
public void setFirstNumber(Long firstNumber) {
getStateHelper().put("firstNumber", firstNumber);
}
public Long getFirstNumber() {
return (Long) getStateHelper().eval("firstNumber");
}
public void setSecondNumber(Long secondNumber) {
getStateHelper().put("secondNumber", secondNumber);
}
public Long getSecondNumber() {
return (Long) getStateHelper().eval("secondNumber");
}
public void setResult(Long result) {
getStateHelper().put("result", result);
}
public Long getResult() {
return (Long) getStateHelper().eval("result");
}
}
See, no local variables anymore. Note that I also removed the need for those ugly manual String-Long conversions by just declaring the right getter return type and setter argument type. JSF/EL will do the conversion automagically based on default converters or custom Converters. As there's already a default one for Long, you don't need to provide a custom Converter.
Unrelated to the concrete problem, you can safely remove the getFamily() method. The UINamingContainer already provides exactly this. If you were implementing NamingContainer interface instead, then you'd indeed need to provide it yourself, but this is thus not the case here. The above backing component examples have it already removed.
I was forced to switch from myfaces (2.1.7) to mojarra (2.1.7). After this I'm getting exceptions like this one below all over the place.
I'm submitting a form, that gives me validation errors. This is correct so far. I submit the form again, that gives me validation errors. This is correct so far. Now I submit the form again and I get the IndexOutOfBoundsException.

I googled this, but haven't found any clue yet.

The stacktrace hints that you're using PrimeFaces.
This problem is known in older versions of PrimeFaces and is actually a bug in PrimeFaces, not in Mojarra. Make sure that you're using the latest PrimeFaces version. As of now that's 2.2.1 when you're using PF2 or 3.2 when you're using PF3.
I have the exact same problem and it is easy to reproduce.
You can reproduce it with the following classes:

The inputText inside the custom component field gets an new Validator added at PreValidateEvent inside the processEvent() method.
If the submit button is now pressed three times in a row with an validation error the ArrayIndexOutOfBoundException will be thrown. I tried to debug and found out that the exception is throwed inside AttachedObjectListHolder#restoreState(FacesContext, Object), afterward my eclipse debugger got crazy...
I think this is a JSF Bug!
