why I can not parse this page-thanks a lot

[SpencerWHJ]

The code is in the following list:

import java.util.ArrayList;
import java.util.List;

import org.htmlparser.Node;
import org.htmlparser.NodeFilter;
import org.htmlparser.Parser;
import org.htmlparser.filters.NodeClassFilter;
import org.htmlparser.parserapplications.StringExtractor;
import org.htmlparser.tags.FrameTag;
import org.htmlparser.util.ParserException;

/*
* This is a bean that holds information about a web page
*/
public class TimeReader {

   private String URL;

   public TimeReader(String URL) {
      setURL(URL);
   }

   public void setURL(String URL) {
      this.URL = URL;
   }

   public static void main(String[] args){
 
    TimeReader tr = new TimeReader("http://www.time.com/time/election2004/article/0,18471,709071,00.html");
    tr.process();
 
  }
   /*
    * Use the HTMLParser to parse a HTML Page
    */
   public void process() {
      StringExtractor se = new StringExtractor (URL);
      String contents = null;
      try {
         contents = se.extractStrings(true);
         System.out.println(contents);
      } catch (ParserException e) {
         e.printStackTrace();
         return;
      }

      }
   }
}

The error code:

Exception in thread "main" java.lang.NullPointerException

I believe this is the same problem as bug #1024045 StringBean crashes on an URL:
