Пользовательский компонент с использованием JSF

Я хочу чтобы создать свой собственный тег, но он не работает

Компонент:

package com;

import javax.faces.component.UIOutput;
import javax.faces.context.FacesContext;
import javax.faces.context.ResponseWriter;
import java.io.IOException;

public class Printer extends UIOutput {
    private String label;

    public String getLabel() {
        return label;
    }

    public void setLabel(String label) {
        this.label = label;
    }

    @Override
    public Object saveState(FacesContext context) {
        Object values[] = new Object[2];
        values[0] = super.saveState(context);
        values[1] = label;
        return ((Object) (values));
    }

    @Override
    public void restoreState(FacesContext context, Object state) {
        Object values[] = (Object[]) state;
        super.restoreState(context, values[0]);
        label = (String) values[1];
    }

    public void encodeBegin(FacesContext context)
            throws IOException {

        ResponseWriter writer =
                context.getResponseWriter();

        writer.startElement("label", this);
        writer.write(label);
        writer.endElement("label");
        writer.flush();
    }

    public String getFamily() {
        return "printer";
    }

    public void encodeEnd(FacesContext context)
            throws IOException {
        return;
    }

    public void decode(FacesContext context) {
        return;
    }
}

Тег

package com;

import javax.faces.component.UIComponent;
import javax.faces.webapp.UIComponentELTag;

public class PrinterTag extends UIComponentELTag {
    private String label;

    public PrinterTag() {
        int i = 10;
    }

    public String getLabel() {
        return label;
    }

    public void setLabel(String label) {
        this.label = label;
    }

    @Override
    public String getComponentType() {
        return "printer";
    }

    @Override
    public String getRendererType() {
        return null;
    }

    protected void setProperties(UIComponent component) {
        super.setProperties(component);
        ((Printer) component).setLabel(label);
    }
}

Я использую 2.0.1-FCS jsf-api / jsf.impl / jstl-1.1.0 jsp-api / servlet-api / standart

В чем я ошибаюсь?
