loading xml file problem in jboss developer studio managed bean

[jayesh_rhds]

I am using JBoss developer Studio 4 GA and JBoss 6x. I am trying to implement Richfaces Data Table Sorting from this link. I have created the jsf project and redirected to the page containing sample code given in the website. I have created managed beans for capitalsBean, capitalsSortingBean, capital, capitalsParser in the faces-config. I have included the java classes as found here.

On running the project i get the error :

Unable to set property capitals for managed bean capitalsBean

I have used the sample java class file:

package org.richfaces.demo.tables;

import java.io.Serializable;
import java.util.List;

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

import org.richfaces.demo.tables.model.capitals.Capital;

@ManagedBean
@SessionScoped
public class CapitalsBean implements Serializable{
    /**
     * 
     */
    private static final long serialVersionUID = -1509108399715814302L;
    @ManagedProperty(value = "#{CapitalsParser.capitalsList}")
    private List<Capital> capitals;

    public CapitalsBean() {
        // TODO Auto-generated constructor stub
    }

    public List<Capital> getCapitals() {
        return capitals;
    }

    public void setCapitals(List<Capital> capitals) {
        this.capitals = capitals;
    }

}

This uses the capitalParser class:

package org.richfaces.demo.tables.model.capitals;

import java.net.URL;
import java.util.List;

import javax.faces.FacesException;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;


@ManagedBean
@ApplicationScoped
public class CapitalsParser {

    private List<Capital> capitalsList;

    @XmlRootElement(name = "capitals")
    private static final class CapitalsHolder {

        private List<Capital> capitals;

        @XmlElement(name = "capital")
        public List<Capital> getCapitals() {
            return capitals;
        }

        @SuppressWarnings("unused")
        public void setCapitals(List<Capital> capitals) {
            this.capitals = capitals;
        }
    }

    public synchronized List<Capital> getCapitalsList() {
        if (capitalsList == null) {
            //ClassLoader ccl = Thread.currentThread().getContextClassLoader();
            //URL resource = ccl.getResource("pages/capitals.xml");
            JAXBContext context;
        try {
            context = JAXBContext.newInstance(CapitalsHolder.class);
            CapitalsHolder capitalsHolder = (CapitalsHolder)context.createUnmarshaller().unmarshal(new FileInputStream("/pages/capitals.xml"));
            capitalsList = capitalsHolder.getCapitals();
        }catch (JAXBException e) {
            throw new FacesException(e.getMessage(), e);
        }
        catch (FileNotFoundException e)
        {
            e.printStackTrace();
        }
        }

        return capitalsList;
    }
}

At times I am able to see just the table column headers without any error displayed and any data displayed. At other times i get the error of property mentioned above. Is there anything wrong in referencing the capitals.xml file? or is there any other error?

With regards,

Now, the page loads with only the headers but the data doesn't!!!
