java.lang.ClassCastException: org.ofbiz.geronimo.GeronimoTransactionFactory

qiyadeng
I create a new component in the hot-deploy.
first, i just add a index.jsp in the component's webapp,everything is ok.

I want to test the GenericDelegator  ,so I create a servlet for test.

this is servlet code:

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package qiya.deng.servlet;

import java.io.*;
import java.net.*;

import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;
import java.util.Set;
import java.util.Vector;
import javax.servlet.*;
import javax.servlet.http.*;
import org.ofbiz.entity.GenericDelegator;
import org.ofbiz.entity.GenericEntity;

/**
 *
 * @author qiya
 */
public class ViewMethod extends HttpServlet {
   
    /**
    * Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
    * @param request servlet request
    * @param response servlet response
    */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
       
       
                    out.println("<html>");
            out.println("<head>");
            out.println("<title>Servlet ViewMethod</title>");  
            out.println("</head>");
            out.println("<body>");
            out.println("

Servlet ViewMethod at " + request.getContextPath () + "

");
            out.println("</body>");
            out.println("</html>");

       
        try {
           
                    GenericDelegator delegator;
        StringBuilder xmlString = new StringBuilder();
        List productStoresList = new Vector();
        try {
            delegator = GenericDelegator.getGenericDelegator("default");
            productStoresList = delegator.findAll("ProductStore");

            Iterator itera = productStoresList.iterator();
            Map newmap;
            xmlString.append("<ProductStores>");
            while (itera.hasNext()) {
                xmlString.append("<ProductStore>");
                GenericEntity elem = (GenericEntity) itera.next();
                newmap = new HashMap();
                newmap = elem.getAllFields();

                Set returnMap = newmap.entrySet();
                for (Iterator i1 = returnMap.iterator(); i1.hasNext();) {
                   
                    Entry en = (Entry) i1.next();
                    xmlString.append("<" + en.getKey().toString() + ">");
                    xmlString.append(en.getValue());
                    xmlString.append("</" + en.getKey().toString() + ">");
                }
                xmlString.append("</ProductStore>");
            }
            xmlString.append("</ProductStores>");
        } catch (Exception exe) {
            exe.printStackTrace();
        }
        System.out.println(xmlString.toString());
        out.println(xmlString.toString());


        } finally {
            out.close();
        }
    }

    // <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code.">
    /**
    * Handles the HTTP <code>GET</code> method.
    * @param request servlet request
    * @param response servlet response
    */
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

    /**
    * Handles the HTTP <code>POST</code> method.
    * @param request servlet request
    * @param response servlet response
    */
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

    /**
    * Returns a short description of the servlet.
    */
    public String getServletInfo() {
        return "Short description";
    }
    // </editor-fold>
}



when i calling the servlet ,there is something wrong information in the console.
