    loading xml file problem in jboss developer studio managed bean

    Jayesh Mahato Newbie

      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,
