Different behaviours when exporting pdf

Question

hi,
i'm facing a strange behaviour when trying to export a pdf that is generated from db. i want to make pdfs available via dialog box. i set disposition to attachment in the response header. whereas FireFox shows the dialog box (as expected), IE renders the pdf in the same window:
   * downloads the report in the requested export format
  public String exportReport()
    String outcome ="error";
    LayoutXSLT layout = null;
    ByteArrayInputStream xslt_bais=null;
    ByteArrayInputStream xml_bais=null;
    byte[] content=null;
    ByteArrayOutputStream fosByte = new ByteArrayOutputStream ();
    String fileName = "Report";
    String disposition="attachment";  
    String contentType="application/pdf";
    FacesContext faces = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) faces.getExternalContext().getResponse();
    FileExporter fex = new FileExporter();
    if (report != null && report.getRowCount()>0)
      try
        layout = accountingRemoteInterface.createXSLTLayout(userID, report.getForm().getId(), XSLT_TYPE.PDF);
      catch (UserAccountingException aex)
        messageError = errorWriter.writeUserAccountingException(rb, aex);
      if (layout != null)
        xslt_bais = new ByteArrayInputStream(layout.getXsltContent()); 
        try
          xml_bais = new ByteArrayInputStream(report.createXMLStream());
          XSLTHelper.doFOP(xslt_bais, xml_bais, fosByte, null);               
          fosByte.flush();
          fosByte.close();        
          content = fosByte.toByteArray();
          reportAvailable=1;
          outcome = fex.export(content, contentType, fileName, disposition, response);
          faces.responseComplete();
        catch (XMLWriterException xex)
          messageError = errorWriter.writeXmlException (rb, xex);
        catch (TransformerException tex)
          messageError = errorWriter.writeTransformerException(rb, tex);
        catch (FOPException foex)
          messageError = errorWriter.writeFopException(rb, foex);
        catch (IOException e)
          e.printStackTrace();
    else
      filteredItems=limitedItems=reportItems="";
      messageError=rb.getString("ERROR_NO_PDF_AVAILABLE");
    return outcome;
  public String export(byte[] cnt, String cType, String fName, String dispo,
      HttpServletResponse response) throws IOException
    String outcome = "error";
    byte[] content = cnt;
    String contentType = cType;
    String fileName = fName;
    String disposition = dispo;
    response.reset();
    response.setContentType(contentType);
    response.setContentLength(content.length);
    response.setHeader("Content-disposition", disposition + ";filename=\"" + fileName + "\"");
    response.setHeader("Cache-Control", "cache, must-revalidate");
    ServletOutputStream out = response.getOutputStream();
    out.write(content);
    outcome = "success";
    return outcome;
    }Any help appreciated!

Answer 1

i checked the server log and couldn't find anything excepting a warning when setting the pdf layout :
WARN  [BreakingAlgorithm] Line 1 of a paragraph overflows the available area. (fo:block, "****************")you mean i shouldn't stop the render response phase, don't you? what's the alternative? a file servlet?
