abstractXsltView problem in Spring mvc

[ksh29]

Hi, guys

I am trying to use AbstractXsltView as the viewer. I have followed the instruction provided by spring, but I am getting errors as

org.springframework.web.util.NestedServletException: Couldn't perform transform in XSLT view with name [home]; nested exception is javax.xml.transform.TransformerException: java.lang.NullPointerException

My controller class,

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class HomeController extends AbstractController{

	Logger logger = Logger.getLogger(HomeController.class);

	@Override
	protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
			HttpServletResponse arg1) throws Exception {
	    Map map = new HashMap();
	    List wordList = new ArrayList();
	        
	    wordList.add("hello");
	    wordList.add("world");
	       
	    map.put("wordList", wordList);
	    logger.debug("hello: " + map.get("wordList"));
	    return new ModelAndView("home", map);
	}

}

and my viewer class,

package xslt;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.mvc.AbstractController;

public class HomeController extends AbstractController{

	Logger logger = Logger.getLogger(HomeController.class);

	@Override
	protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
			HttpServletResponse arg1) throws Exception {
	    Map map = new HashMap();
	    List wordList = new ArrayList();
	        
	    wordList.add("hello");
	    wordList.add("world");
	       
	    map.put("wordList", wordList);
	    logger.debug("hello: " + map.get("wordList"));
