    Trouble implementing XSLT in seam application

    Raghavan TV Newbie

      We are implementing a generic dynamic view generation layer that can render the output using XSLT. We extract the SOAP body from the soap response, apply XSLT to generate template based html output.


      The same implementation works fine using a simple JSP/Servlet implementation.


      But when we implement the same logic within seam, we get an exception

          Hi Raghav,
                   I have tried the same and able to generate dynamic html




          public static void translate(String xmlFile, String xslFileName,StreamResult result) throws Exception
          {                         
                  try
                  { 
                  File xmlFile = new File(xmlFile);
              File xsltFile = new File(xslFileName);

              // JAXP reads data using the Source interface
              Source xmlSource = new StreamSource(xmlFile);
              Source xsltSource = new StreamSource(xsltFile);

              // the factory pattern supports different XSLT processors
              TransformerFactory transFact =
                      TransformerFactory.newInstance();
              Transformer trans = transFact.newTransformer(xsltSource);

               trans.transform(xmlSource, result);
             
                  }
                  catch (Exception e)
                  {
                    e.printStackTrace();
                                 
                  }
                 
          }
