1. Managed Bean

[code lang=”java”] package net.javabeat.jsf;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

@ManagedBean
@SessionScoped
public class MessageBean {

private String message = "";

public String getMessage() {
return message;
}

public void setMessage(String message) {
this.message = message;
}

public String sendMessage() {
return "inbox";
}

}
[/code]

The managed bean (MessageBean) contains a property of type String called message.
The managed bean (MessageBean) provides an action for navigating from writing message page into viewing of message page.
