Hi I'm trying to test jsf's navigation rules.
My Person bean:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean
@SessionScoped
public class Person {
private int id;
private String name;
private int age;
public Person(){
id = 1;
name = "No name!";
age = 0;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String validate(){
if(this.name.equals("Evgeny")){
return "success";
}else{
return "failure";
}
}
}
My faces-config.xml:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
<navigation-rule>
<from-view-id>/view.xhtml</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/destination.xhtml</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>failure</from-outcome>
<to-view-id>/view.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
</faces-config>
And that's my form:
<!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:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:body>
<h:form>
<h:outputText>Some Text!</h:outputText>
Name: <h:inputText value="#{person.name}" id="inName"></h:inputText>
<br></br>
Age: <h:inputText value="#{person.age}" id="inAge"></h:inputText>
<br></br>
<h:commandButton value="OK" action="#{person.validate}"></h:commandButton>
</h:form>
</h:body>
</html>
When I try to call person.validate I get javax.el.MethodNotFoundException Why that happens?
I'm using MyFaces2.0.4 and Tomcat 7
Save all files, rebuild the project, redeploy the webapp and restart your server.
In other words, everything looks fine. You are just not running the code you think you're running.
