Unable to set request character encoding to UTF-8 from context [duplicate]

I'm trying to implement example from Primefaces into WAB package.

    <?xml version='1.0' encoding='UTF-8' ?>

import org.glassfish.osgicdi.OSGiService;

// Update form example
@Named("LinuxController")
@SessionScoped
public class Linux implements Serializable {

    private CartesianChartModel categoryModel;

    public Linux() {
        createCategoryModel();

    }

    public CartesianChartModel getCategoryModel() {
        return categoryModel;
    }

    private void createCategoryModel() {
        categoryModel = new CartesianChartModel();

        ChartSeries boys = new ChartSeries();
        boys.setLabel("Boys");

        boys.set("2004", 120);
        boys.set("2005", 100);
        boys.set("2006", 44);
        boys.set("2007", 150);
        boys.set("2008", 25);

        ChartSeries girls = new ChartSeries();
        girls.setLabel("Girls");

        girls.set("2004", 52);
        girls.set("2005", 60);
        girls.set("2006", 110);
        girls.set("2007", 135);
        girls.set("2008", 120);

        categoryModel.addSeries(boys);
        categoryModel.addSeries(girls);
    }
}

When I try to access the JSF page the page is empty. I get this error in Glassfish log file:

How I can fix this problem? I suppose that this maybe caused by POM configuration?

JSF/Facelets uses UTF-8 by default already which get set during restoring the view, however the PrimeFaces ajax view handler tries to access a request parameter before the view get restored, so the server's default character encoding will be used instead which is ISO-8859-1. You need to add the following entry to the <glassfish-web-app> of your /WEB-INF/glassfish-web.xml file to instruct the Glassfish server to use UTF-8 as well:

<parameter-encoding default-charset="UTF-8"/>
