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
