请问高手们一个关于Servlet和xml的一个问题！！！~~~~~
现在我有一个xml
aaa.xml
<?xml   version= "1.0 "   encoding= "UTF-8 "?>
<?xml-stylesheet   type= "text/xsl "   href= "DeviceGroup.xsl "?>
<languages>
<language> zh_CN.xml </language>
</languages>

zh_CN.xml
<?xml   version= "1.0 "   encoding= "UTF-8 "?>
<root>
      <table> 你好 </table>
</root>

en_US.xml
<?xml   version= "1.0 "   encoding= "UTF-8 "?>
<root>
      <table> hello </table>
</root>

bbb.xsl
<?xml   version= "1.0 "   encoding= "UTF-8 "?>  
<xsl:stylesheet   version= "1.0 "   xmlns:xsl= "http://www.w3.org/1999/XSL/Transform ">  
  <xsl:output   method= "xml "   version= "1.0 "   encoding= "UTF-8 "   indent= "yes "/>  
  <xsl:template   match= "/ ">  
  <groups>  
      <xsl:apply-templates   select= "/root/table "/>  
  </groups>  
  </xsl:template>  
  <xsl:template   match= "root/table ">  
  <table   border= "2 ">
          <tr>
<td> <xsl:copy-of   select= "document(.)//table "/> </td>
          </tr>
</table>
  </xsl:template>  
</xsl:stylesheet>  

还有一个Servlet当中的doGet方法
public   void   doGet(HttpServletRequest   request,   HttpServletResponse   response)throws   ServletException,   IOException,
java.net.MalformedURLException   {
          try   {
response.setContentType( "text/html;   charset=UTF-8 ");
PrintWriter   out   =   response.getWriter();
Locale   clocale   =   request.getLocale();
StringWriter   resultStringWriter   =   new   StringWriter();
XSLTProcessor   processor   =   XSLTProcessorFactory.getProcessor();
processor.setStylesheetParam( "lpfile ",   "clocale ");
String   xml_doc   =   "E:/test/aaa.xml ";
String   stylesheet   =   "E:/test/bbb.xsl ";                                                       processor.process(new   XSLTInputSource(xml_doc),new   XSLTInputSource(stylesheet),   new   XSLTResultTarget( resultStringWriter));
              out.write(resultStringWriter.toString());
              out.close();
    }   catch   (SAXException &n
