Servlet can't open a download window on IE, but open it on FireFox

Question

Hello everyone,
I created a attachment Pdf file by servlet. When I run at simulation, "inline" and “attachment” both worked fine.
However, web application doesn't work on IE, either for "inline" or "attachment".
When I tried Firefox, both work fine!
I am crashed. Is there anyone who have some clues for this situation?
my code:     public void doPost(HttpServletRequest request, HttpServletResponse resp)
     throws javax.servlet.ServletException, java.io.IOException
          ByteArrayOutputStream baosPDF = null;
          pdfDocPage=new PdfDocPage(request,resp);//get data
          try
               //get value of parameters from shortcut panel.
               baosPDF = generatePDFDocumentBytes(request, resp, this.getServletContext());
               StringBuffer sbFilename = new StringBuffer();
               sbFilename.append("filename_");
               sbFilename.append(System.currentTimeMillis());
               sbFilename.append(".pdf");
               resp.setHeader("Cache-Control", "must-revalidate");
               resp.setContentType("application/pdf");
               StringBuffer sbContentDispValue = new StringBuffer();
               sbContentDispValue.append("attachment");
               sbContentDispValue.append("; filename=");
               sbContentDispValue.append(sbFilename);
               resp.setHeader("Content-disposition",sbContentDispValue.toString());
               resp.setContentLength(baosPDF.size());
               ServletOutputStream sos;
               sos = resp.getOutputStream();
               baosPDF.writeTo(sos);
               sos.flush();
          catch (DocumentException dex)     {...}
                catch (DbException e) {.....     }
          finally
               if (baosPDF != null)
                    baosPDF.reset();
     @Override
     public void doGet(HttpServletRequest request, HttpServletResponse resp)
     throws javax.servlet.ServletException, java.io.IOException
          doPost(request,resp);
     } To create pdf servlet window:com.google.gwt.user.client.Window.open( "PdfService?op=" + para1+ "&para2=" +para2, "_self", ""); Thanks in advance,
Helen

Answer 1

Hi paul,
I found out that WSSO blocked the pop-up window first time. if I tried more than one time, it works fine. Now, I putted the application to a different path without WSSO log-in requirement, it works.
Now, I am striving to the WSSO log-in part. Is there any good idea for that though?
By the way, I am a pretty brand new Java programmer. I have so many things to learn...
Thanks for your helps,
Helen
