My requirement is to display tables from database in Graph format and I am using fiji for the same. And on doing so I am encountering and exception,
My jsp page is as follows.

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:fiji="http://exadel.com/fiji">
    <fiji:columnChart id="columnChartOne" value="#{GraphBean.monthMap}" title="One-series Column Chart" barCaption="none"
                      barColors="#{GraphBean.colors}" captionX="Months" captionY="Amount" toolTipValue="{y} {name} are sold in {x}"
                      subtitle="Hardware sales per month" width="400" height="400">
        <fiji:chartData type="name" value="#{GraphBean.names}" />
    </fiji:columnChart>
</ui:composition>

My bean is as follows :

import java.util.ArrayList;
import java.util.Date;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Random;


public class GraphBean {

    private Integer data;
    private  Map<String, Integer> monthMap = new LinkedHashMap<String,Integer>();
    private ArrayList<String> names = new ArrayList<String>();
    private ArrayList<String> colors = new ArrayList<String>();
    Random rnd = new Random(new Date().getTime());

    public GraphBean() {
        super();
        generateData();
    }

    private void generateData() {
        monthMap.put("January", getData());
        monthMap.put("February", getData());
        monthMap.put("March", getData());
    }

    public Map<String, Integer> getMonthMap() {
        return monthMap;
    }

    public ArrayList<String> getNames(){
        names.add("Motherboards");
        return names;
    } 

    public ArrayList<String> getColors(){
        colors.add("#5db2c2");
        return colors;
    } 

    public Integer getData() {
        data = rnd.nextInt(50);
        return data;
    }
}

I have made entry for the bean in the faces-config.xml.

    In JSF, you could render the page either with facelet or with JSP (although not recommended)
    As far as I see, you are trying to load JSP page, while adding a facelet tag:

    <ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:fiji="http://exadel.com/fiji">
...
</ui:composition>

    . If you would like to use the pages with facelet, you can download an example that is using facelet here . As you can see, the name of the pages are postfixed with .xhtml and not with .jsp.

    If you would like to use JSP your page has to be:

        <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
    <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
    <%@ taglib uri="http://exadel.com/fiji" prefix="fiji" %>

    <html>
     <head>
      <title>enter your name page</title>
     </head>
     <body>
<f:view>
            <fiji:columnChart id="columnChartOne" value="#{GraphBean.monthMap}" title="One-series Column Chart" barCaption="none"
                              barColors="#{GraphBean.colors}" captionX="Months" captionY="Amount" toolTipValue="{y} {name} are sold in {x}"
                              subtitle="Hardware sales per month" width="400" height="400">
                <fiji:chartData type="name" value="#{GraphBean.names}" />
            </fiji:columnChart>
       </f:view> 
    </body>
    </html>

    Again, I would recommend to you to use facelet, if it’s a new project.
