Daniel,
Is this (issues.apache.org) email id where I need to create an issue? As I
am new so not aware of this email id.
As per the understanding sending to '[email protected].
Also attaching the example file -
Problem Description
In my application, its a Document Management application which manages PDF
documents.
so while this PDF documents created in Version '1.4(5.x) or later' by
Adobe Professional 9.0 then 1 revision will be uploaded and pdf generated
successfully.
But If I am trying to create its new revision say 2, then at the time of
creation of 'PDF difference file', the line# 11 below -
1// Text Stripper initialisation
2 PDFTextStripper stripper = new PDFTextStripper();
3 pdfStream = new ByteArrayInputStream(pdf_buf);
4
5 // Open and load PDF document content.
6 document = PDDocument.load(pdfStream);
7 // Get the document content in String format.
8 // And suppress all non ascii characters
9 //try
10 //{
11 PDF_text = stripper.getText(document);
will return null as 'PDF_text' instead of text document of the PDF file.
Thanks & Regards,
Pooja Gupta

Pooja,
Would you create an issue at issues.apache.org for this and attach an
example file?
Thanks.
