Technically this is not an iText issue but as I had the time to actually
respond this time, here it is..
You're doing that all wrong...
Create the PDF in a memory stream first.
Then use the following:
(do bear in mind that this is VB code but does lend to conversion to any
other language as I've done to C# myself).
HttpContext.Current.Response.Buffer = True
HttpContext.Current.Response.ClearContent()
HttpContext.Current.Response.ClearHeaders()
HttpContext.Current.Response.ContentType =
"application/pdf"
HttpContext.Current.Response.AddHeader("Content-Disposition",
"attachment;filename=" & usrnm & ".pdf")
HttpContext.Current.Response.BinaryWrite(mStream.GetBuffer())
HttpContext.Current.Response.End()

Subject: [iText-questions] Open an existing PDF instead of creating blank
This should be easy but I'm having a hard time with it. I'm currently doing
the following:
// START OF DOCUMENT
response.setContentType("application/pdf");
Document document = new Document();
try{
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(document, buffer);
document.open();
PdfFormField field = PdfFormField.createSignature(writer);
field.setWidget(new Rectangle(218, 577, 285, 589),
PdfAnnotation.HIGHLIGHT_INVERT);
field.setFieldName("mySig");
field.setFlags(PdfAnnotation.FLAGS_PRINT);
writer.addAnnotation(field);
// END OF DOCUMENT
document.close();
DataOutput dataOutput = new DataOutputStream(response.getOutputStream());
byte[] bytes = buffer.toByteArray();
response.setContentLength(bytes.length);
for(int i = 0; i < bytes.length; i++) {
dataOutput.writeByte(bytes[i]);
}
}catch(DocumentException e){
e.printStackTrace();
}
but I need to open an existing PDF at this location below and do the above.
String rootPath = System.getProperty("catalina.home");
rootPath = rootPath + File.separator + "webapps" + File.separator + "ROOT" +
File.separator;
rootPath = rootPath + "test/reportjsps/MyForm.pdf";
how would I modify the above so that it opens this existing PDF?
thanks
