Question

I have a web application which uses JSF 2.0 mojjarra. i want to put my managed bean classes to a package named like this.

package com.myapp.managedbean

How can i tell the jsf to scan this package for annotated managed beans.

My maven dependencies

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>

</dependency>
 <dependency>
  <groupId>com.sun.faces</groupId>

    <artifactId>tomcat-servlet-api</artifactId>  
    <version>7.0.26</version>  
    <scope>provided</scope>  
  </dependency>  

My managed bean :

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

@ManagedBean(name="helloWorld")
@SessionScoped
public class HelloWorld{

    @ManagedProperty(value="Hello World")
    private String a;

public String getA() {
    return a;
}

public void setA(String a) {
    this.a = a;
}

}

And my page :

<h:head></h:head>

<h:body>

<p:outputLabel for="extended"  />  
            <p:inputText id="extended" value="#{helloWorld.a}" />

</h:body>

</html>

The page only shows an empty text field.

You don’t have to specify just place the annotations above your class name , like this
It will find them by itself…

@ManagedBean
@SessionScoped
public class MyBean {

instead of

@ManagedProperty(value="Hello World")
private String a;

just do

private String a = "Hello World";

this is not how ManagedProperty are used, do some google about it

in general ManagedProperty are for injecting values / beans

here an example how to inject another bean

@ManagedProperty(value = "#{someOtherBean }")
private SomeOtherBean someOtherBean ; // + getter and setter
