Problem in importing two different classes with same name...

Question

I have to import two different classes in my program with the same name....
import org.apache.lucene.document.Document;
import org.w3c.dom.Document;
//    I AM USING THE DOCUMENT FROM W3C PACKAGE HERE....
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
                 DocumentBuilder builder = factory.newDocumentBuilder();
                 InputSource is = new InputSource( new StringReader( tempString ) );
                 d = builder.parse( is );
                 NodeList images = d.getElementsByTagName("img");
                 int length = images.getLength();
                 for(int i = 0;i<length;i++)
                     Node image = images.item(i);
                     String tempAltText = image.getAttributes().getNamedItem("alt").getNodeValue();
                     altText = altText.concat(" ").concat(tempAltText);
                 }and the error i am getting is
[javac] C:\Documents and Settings\sumit-i\WolframWorkspaces\Base\WolframNutch\src\java\com\wolfram\nutch\indexer\InfoCenterFilter.java:20: org.apache.lucene.document.Document is already defined in a single-type import

Answer 1

now i changed the code to
import org.apache.lucene.document.Document;
import org.w3c.dom.Document;
org.w3c.dom.Document d = null;
try{
     System.out.println("in author");
               URL url = new java.net.URL(urlString);
               java.net.URLConnection conn = url.openConnection();
               BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
               while ((in.readLine()) != null)
                    //tempString = tempString.concat(in.readLine());
                    String temp = in.readLine();
                    tempString = tempString + " " + temp;
               System.out.println("the string in author" + tempString);
                in.close();
                DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
                 DocumentBuilder builder = factory.newDocumentBuilder();
                 InputSource is = new InputSource( new StringReader( tempString ) );
                 d = builder.parse( is );
                 NodeList images = d.getElementsByTagName("img");and their is only one error i am getting ...and that is
