Introduction to JSF

1. Managed Bean

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";
	}

}

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.
