I keep getting this message when trying to run the code below. It is supposed to show the test from the document to be uploaded. This is a Java Server Faces program. Why am I getting this message:Unable to find matching navigation case with from-view-id '/upload.xhtml' for action 'vidClass2.upload' with outcome 'vidClass2.upload'

in case you are using JavaBeans components on yours page you should use expression #{bean.method} in action.
<h:commandButton id="button" value ="upload" action ="#{vidClass2.upload}"/>

Given the component: https://www.primefaces.org/showcase/ui/input/oneMenu.xhtml
Full source for my test is at: https://github.com/dannymk/PrimefacesTest
Can't get the component to work with an Object using a converter. Not sure how to solve this one.

I get errors like:

It does not seem to matter what I change and believe me I have tried plenty of implementations of the converter and in the view using "#{palyerConverter}" instead of "playerConverter" and still can't get it to work.
Your problem is at this line:
<f:selectItem itemLabel="Select One" itemValue="" />
Currently you are passing an empty string as the itemValue, which is not expected by your converter. Either use itemValue="#{null}" or totally remove the itemValue from the no select option.

Finally got it to work with just a few changes thanks to #Jasper de Vries:

I'm doing a hotel room reservation page with Java Server Faces. I have a base template that contains a hotel search, with an index template that is where I show the results. I'm loading all the hotels on the front page, like cover. And I show only 9 hotels so that they do not overflow the hotels of the DIV:
Ok, I have only 10 hotels registered in the database in total .... I want to make a pagination for my page where I display only 9 hotels per page .... the result of having this, as I have 10 hotels in the database, it would be that on the next page I should only see 1 single hotel.
This is my index page:
<?xml version='1.0' encoding='UTF-8' ?>

<h:column>
<h:outputLabel value="#{res.c}" escape="false"/>
</h:column>
</h:dataTable>
</h:form>
</ui:define>
</ui:composition>
</body>
I am using a dataTable to display the results. I have two classes: a class that handles rows of the dataTable, and another class that constructs the display boxes of each hotel
With this class I construct each box in the table:
package Clases;
public class ResultElement {
private String nombre, imagen, localidad;
private String display;
public ResultElement(String nombre, String imagen, String localidad){
this.nombre=nombre;
this.imagen=imagen;
this.localidad=localidad;
display = "<div id='HotP'><b><p style=\"text-align:center;font-
style:italic;color:red\">" + nombre + "</p></b>"
+"<img src=\"resources/images/" + imagen +
"\"style=\"width:160px;height:70px;border:1px solid gray;\"/><br>"
+ "<span style=\"color: darkblue;text-align: center;\">"+
localidad +"</span></div>";
}
/**
* #return the nombre
*/
public String getNombre() {
return nombre;
}
/**
* #param nombre the nombre to set
*/
public void setNombre(String nombre) {
this.nombre = nombre;
}
/**
* #return the imagen
*/
public String getImagen() {
return imagen;
}
/**
* #param imagen the imagen to set
*/
public void setImagen(String imagen) {
this.imagen = imagen;
}
/**
* #return the localidad
*/
public String getLocalidad() {
return localidad;
}
/**
* #param localidad the localidad to set
*/
public void setLocalidad(String localidad) {
this.localidad = localidad;
}
/**
* #return the display
*/
public String getDisplay() {
return display;
}
/**
* #param display the display to set
*/
public void setDisplay(String display) {
this.display = display;
}
}
With this class I manage the rows of the table. I show 3 results per row:
package Clases;
public class DisplayResult {
private String A, B, C;
public DisplayResult(String a, String b, String c){
A = a;
B = b;
C = c;
}
/**
* #return the A
*/
public String getA() {
return A;
}
/**
* #param A the A to set
*/
public void setA(String A) {
this.A = A;
}
/**
* #return the B
*/
public String getB() {
return B;
}
/**
* #param B the B to set
*/
public void setB(String B) {
this.B = B;
}
/**
* #return the C
*/
public String getC() {
return C;
}
/**
* #param C the C to set
*/
public void setC(String C) {
this.C = C;
}
}
This class is where I will load the cover of the page and perform searches:

I thought of controlling the pagination of my page with my arrayList but the truth is that I do not know how to place it in the dataTable ...
Is there an easy and practical way to do it?
Native JSF does not have any support/have components for pagination.
You could go for a Component library like Primefaces, which has a pagination components like DataGrid .
While i create a application my page bean not saved in #FlowScoped . by default stored in Request scope here my code :
enter code here
package com.webage.beans;
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.flow.FlowScoped;
#ManagedBean(name="flow1")
#FlowScoped(value = "flow1")
public class Flow1Bean implements Serializable {
public String cusName;
public String city;
public String getName() {
return this.getClass().getSimpleName();
}
public String doReturnValue() {
return "return1";
}
/**
* #return the cusName
*/
public String getCusName() {
return cusName;
}
/**
* #param cusName the cusName to set
*/
public void setCusName(String cusName) {
this.cusName = cusName;
}
/**
* #return the city
*/
public String getCity() {
return city;
}
/**
* #param city the city to set
*/
public void setCity(String city) {
this.city = city;
}
}
My Xhtml file here i'm getting input from page and store it in page bean.:
<p>
<span id="param1FromFlow1">Flow bean
param1Value:<h:inputText id="input"
value="#{flow1.cusName}" /> </span>
</p>
<h:outputText value="#{null != facesContext.application.flowHandler.currentFlow}" >
</h:outputText>
<p></p>
<h:commandButton type="submit" value="Next" styleClass="commandButton"
id="button1" action="flow1a"></h:commandButton>
<p></p>
The below code return "false" in flow/flow1.xhtml file
<h:outputText value="#{null != facesContext.application.flowHandler.currentFlow}" >
</h:outputText>
Flowscope is a CDI scope. Use #Named instead of #ManagedBean.
I am reading Java EE 7 tutorial. In chapter 13.12, there is an example application, ajaxguessnumber. I run the example in Glassfish 4 and everything works fine. I then put System.out.println in bean constructor and I realized that the constructor is being called twice during initial page loading. Why is that so, even for #SessionScoped bean?

Here is the bean DukesNumberBean

}
if (userNumber == null) {

} else {

}
}
}
Any help would be much appreciated. Thank you.
This happens because the scoped objects and injected by CDI using proxies. CDI has first to create a proxy of your object that is a subclass of your real object - this is the first time your constructor gets called because when you instantiate a subclass the parent constructor is always called. And then CDI instantiates your real object in order to inject it - this is the second time your constructor gets called.
A better approach is to put your initialization login in a #PostConstruct method like this.
#PostConstruct
public void init() {
Random randomGR = new Random();
long range = maximum+minimum+1;
randomInt = (int) (minimum + randomGR.nextDouble()*range);
System.out.println("Duke's number: " + randomInt);
}
It will be called only once - when the real object gets instantiated. More info about the proxies you can find here.
EDIT:
I just found another explanation of the problem - here.
I try to learn JSF and encountered on a problem connected with ManagedProperty. However I have tried to use it, it always failed - null exception pointer. What am I doing wrongly?
I have read some "similar posts" on stackoverflow, but they did not helped to me. (I use GlassFish 4.0, JSF 2.2, JDK 1.7, Netbeans 7.3.1 (Java EE pack) and Java EE 6.0)

#ManagedProperty is managed bean annotaion, that can't be used with CDI. In above code, you used CDI bean i.e. #Named that is default in JSF 2.2. In this case you can't use ManagedProperty. Please read following line copied from Java EE docs of ManagedBean.
If this annotation is present on a class that does not have the
ManagedBean annotation, the implementation must take no action on this
annotation.
For details see the link:
http://docs.oracle.com/javaee/6/api/javax/faces/bean/ManagedProperty.html
So, use #Inject instead of #ManagedProperty for CDI bean.
#Inject
private User user;
Note that a getter/setter is unnecessary here.
