Hi,
that works for me:
... building PDF ...
then finish it
// add a page break
document.newPage();
// step 5: we close the document (the outputstream is also
closed
// internally)
document.close();
// we have written the pdfstream to a ByteArrayOutputStream,
// now we are going to write this outputStream to the
// ServletOutputStream
// after we have set the contentlength
response.setContentType("application/pdf");
response.setHeader("Content-Disposition","attachment;filename=fileName.pdf")
;
response.setContentLength(baos.size());
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
out.flush();
... catch block ...
then
return null; // in ActionForward execute()
Best Regards.
Michael.
