@Named bean not found in JSF page

I am using Netbeans 8.0.2. I created a very simple (what is intended to be a JSF) web application by using File -> New Project -> Java Web : Web Application.

I am trying to print a @Named bean's instance variable in my index.xhtml page but its not working as expected. I am deploying the application with the green "Run Project" button in Netbeans, which packages, deploys and launches the browser automatically.

Managed Bean

package my.first.jfs;

import java.io.Serializable;
import javax.faces.bean.SessionScoped;
import javax.inject.Named;

@Named
@SessionScoped
public class MyFirstBean implements Serializable {

    public String name = "Insert your Name here...";

    public MyFirstBean() {
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

Below is a screenshot of my browser after launching the app.

Please let me know if any additional info is required. Thanks!

Solution

  • If you only want to use JSF framwork, you should replace @Named annotation with @ManagedBean. I think it will solve your problem in this case.

    For more details, read this topic: Difference between @Named and @ManagedBean annotations in JSF2.0 Tomcat7

    and this "sub-one": ManagedProperty in CDI @Named bean returns null
