    how to display response in new window

    Wingman Boby Newbie

      Hi how to display data in new window though servlet

       

      here am  calling servlet from my managed bean

       

      <h:form>


      <h:commandLink id="viewFileData"  action="#{viewFileDataMBean.downloadFile}" value="fileName"></h:commandLink>





      </h:form>

       

       

      and my managed bean has the method like

       

      public void downloadFile() throws IOException, SQLException{

                    String url = "/DisplayFile ";

                    FacesContext context = FacesContext.getCurrentInstance(); 

              try { 

                 context.getExternalContext().dispatch(url); 

              }catch (Exception e) { 

                 e.printStackTrace(); 

              } 

              finally{ 

                 context.responseComplete(); 

              } 

       

       

      and my Servlet code is

       

      public class DisplayFile extends HttpServlet {

       

       

                public void doPost(HttpServletRequest request, HttpServletResponse response)

                                    throws ServletException, IOException {

       

       

                            File                f        = new File("C:/files/123.txt");

                      int                 length   = 0;

                      ServletOutputStream op       = response.getOutputStream();

                      ServletContext      context  = getServletConfig().getServletContext();

                      String              mimetype = context.getMimeType( "E:/images/123.txt" );

                      System.out.println("......"+mimetype);

                   

                      response.setContentType("text/html");

                      response.setContentType( (mimetype != null) ? mimetype : "application/octet-stream" );

                      response.setContentLength( (int)f.length() );

                      response.setHeader( "Content-Disposition", "inline; filename=\"" + f.getName() + "\"" );

       

       

                      byte[] bbuf = new byte[2024];

                      DataInputStream in = new DataInputStream(new FileInputStream(f));

       

       

                      while ((in != null) && ((length = in.read(bbuf)) != -1))

                      {

                          op.write(bbuf,0,length);

                      }

       

       

                      in.close();

                      op.flush();

                      op.close();
