Managedbean could not be create Can't set managed bean property
[nobr]I know that many people have had this issue in the past, well I have it now ,and I have tryed every solution I have found in the forums.
Some how I cannot get to create the managed bean.
I have used the myeclipse framework to create a simple example of JSF
I am using JDK 5
JBOSS 4
JSF Sun 1.1_01
here is the think I have two String properties that are inicialized by the user in a form, then in the next page I print another managed-bean.
When the app starts the container is supposed to create the bean from the faces-config. But I allways get:
13:28:37,657 ERROR [ApplicationImpl] Managedbean CentralBean could not be created Can't set managed bean property: 'cuantos'.
javax.faces.FacesException: Can't set managed bean property: 'cuantos'.
I have tryed to inicialize the property in the config file, but no matter what type I choose I allways get the same exception.
If I erase the property from the config file, then the form is displayed but at the next page I get a Unknown property'cuantos'
Here is my faces-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC"-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN""http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config >
<managed-bean>
<managed-bean-name>CentralBean</managed-bean-name>
<managed-bean-class>org.invias.bean.CentralBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>user</property-name>
<property-class>java.lang.String</property-class>
<null-value></null-value>
</managed-property>
<managed-property>
<property-name>password</property-name>
<property-class>java.lang.String</property-class>
<value></value>
</managed-property>
<managed-property>
<property-name>cuantos</property-name>
<value>1</value>
</managed-property>
</managed-bean>
here is my java code:
publicfinalclass CentralBeanextends Objectimplements Serializable{
/**
*
*/
privatestaticfinallong serialVersionUID = 151531;
private Proceso procesos;
private Integer cuantos;
/**
*
*/
private String password =new String();
/**
*
*/
private String user =new String();
....
public String loginUser(){
System.out.println("loginuser");
//conecto con los beans.
//InitialContext ctx = new InitialContext();
//Object objref = ctx.lookup("ejb/Central");
//org.invias.ejb.CentralBean SessionBean = (org.invias.ejb.CentralBean) PortableRemoteObject.narrow(objref, CentralHome.class);
//SessionBean.setNombre(getUser());
//es = SessionBean.getText();
FacesContext facesContext = FacesContext.getCurrentInstance();
FacesMessage facesMessage =new FacesMessage("Nuevo Mensaje");
facesContext.addMessage("loginForm", facesMessage);
if("dani".equals(getUser()) &&"myeclipse".equals(getPassword())){
procesos =new Proceso();
cuantos =new Integer(1);
return"success";
}
return"failure";
}
.....
public Integer getCuantos(){
return cuantos;
}
publicvoid setCuantos(Integer cuan){
this.cuantos=cuan;
}
/**
* @param cuantos
*/
publicvoid setCuantos(int cuan){
System.out.println("setCuantos");
this.cuantos =new Integer(cuan);
}
/*
* (non-Javadoc)
* @see java.lang.Object#toString()
*/
public String toString(){
return"";
}
}
fairly simple....
This is the first page, that is supposed to recieve the user, get his user and password, and then proceed to display his info.
Here is my login.jsp:
<f:view>
<f:loadBundle basename="org.invias.MessageBundle" var="bundle" />
Login Page<br>
<h:form id="loginForm" rendered="true">
<h:outputLabel rendered="true" for="user" value="#{bundle.user_label}"/>
<h:inputText value="#{CentralBean.user}" rendered="true" required="true" id="user" />
<P><h:outputLabel rendered="true" for="password" value="#{bundle.password_label}" />
<h:inputSecret value="#{CentralBean.password}" rendered="true" required="false" redisplay="false" id="password" /><BR>
<h:commandButton value="#{bundle.login_button}" rendered="true" action="#{CentralBean.loginUser}" id="submit" />
</P></h:form></f:view>
Once I have user and password, I will look in a DB for the user info, for now I am trying to print some dummy data, but...
here is my code:
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

I have used the guide in a step by step manner, it worked well, but when I tryed to extend the example it failed. I have no idea why.
I all ready have a book about JSF, and according to the book my faces-config is ok, and my java code is working... So I am missing something, please help me find out, I have lost two days in this simple problem.
Thanks for the help
