Hello everyone,
I have created a new DocumentType. That document will contain pdf files as
content. When I create this document and select the pdf file at its creation
view, a watermark with a date (which is one field of that creation view) is
added to the pdf file. At this point, everything works fine. The pdf file is
attached as content, and if you open it, the correct watermark was added. The
problem comes when I try to modifiy it.
If I change that date in the modification tab, I want the watermark updates,
but I don't get it. I have tried doing it in a java bean associated to xhtml
view, and also in a listener, capturing "documentModifed" event, but it always
remains old watermark. Any error is displayed, and everything seems to work
fine.
To add watermark to the pdf file, I use a temporal file, and I have checked
that that temporal file is created in my filesystem.
Has anyone any idea why this is not working?
This is relevant code:
private String addWaterMark(InputStream content, String fecha, String numReg){
String res = "";
try
{
PdfReader reader = new PdfReader(content);
int n = reader.getNumberOfPages();
// Create a stamper that will copy the document to a new file
File file = File.createTempFile("temp", ".pdf");
PdfStamper stamp = new PdfStamper(reader,
new FileOutputStream(file));
int i = 1;
PdfContentByte under;
PdfContentByte over;
drawRectangle(stamp,reader.getPageSize(1).getWidth()-142,reader.getPageSize(1).getHeight()-
62,140,60);
addWaterMark(stamp, reader.getPageSize(1).getWidth()-140,
reader.getPageSize(1).getHeight() - 19, 15, fecha, numReg);
stamp.close();
res = file.getPath();
return res;
}catch (Exception de) {
}
return "";
}
...........
}else if(event.getName().equals("documentModified") &&
doc.getType().equalsIgnoreCase("Correspondencia")){
Calendar fecha =
(Calendar)doc.getProperty("correspondencia", "fecha");
String fechaString =
fecha.get(fecha.DAY_OF_MONTH) + "/" + (fecha.get(fecha.MONTH)+1) + "/" +
fecha.get(fecha.YEAR);
Blob blob =
(Blob)doc.getProperty("file", "content");
if(blob!= null){
String filePath = this.addWaterMark(blob.getStream(), fechaString, numeroReg);
File
file = new File(filePath);
if(file.exists()){
FileBlob fb = new FileBlob(file);
fb.setMimeType(blob.getMimeType());
fb.setEncoding(blob.getEncoding());
doc.setProperty("file", "content", fb);
}
}
//
documentManager.saveDocument(doc); ---> this line provokes bucle
documentManager.save();
}
