Refactor Managed Bean

Hi Everyone,

I am new at JSF and I am puzzled as to why when I refactor my backing bean, my JSF doesn't work anymore. Let me explain with code.

/*

 * and open the template in the editor.
 */
// filename is Hello.java
package hello;

import javax.faces.bean.ManagedBean;

@ManagedBean
public class Hello {

final String world = "Hello World!";

public String getworld() {
        return world;
    }
}

//My beanhello.xhtml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html">
    <h:head>
        <title>Facelet Hello World</title>
    </h:head>
    <h:body>
        #{[b]hello.world[/b]}
    </h:body>
</html>

//My web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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-app_3_0.xsd">
    <context-param>
        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Development</param-value>
    </context-param>
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
    <welcome-file-list>
        <welcome-file>faces/beanhello.xhtml</welcome-file>
    </welcome-file-list>
</web-app>

Everything works fine. When I run it, my browser displays "Hello World!" The minute I refactor (rename) Hello class to HelloTest and change hello.world (in my beanhello.xhtml) to hellotest.world, it doesn't work when I run it again. My browser display a blank page. I stopped and started the server, rebuild, redeploy and nothing works.

What am I doing incorrectly?

Thank you in advance.

If the new refactored Managed Bean name is HelloTest, you should call it from helloTest from the page, not hellotest. That should work.

Ah yes, thank you Daniel! It works.
