Thx for the very fast answer.
new StandardDecryptionMaterial( password );
I have no password. The pdf is a public user manual.
Use an empty password :-)

Betreff: Re: extracting text from an "encrypted" pdf
Am 08.05.2015 um 17:36 schrieb Clemens Wyss DEV:
When I try to extract an "encrypted" (which can be read in AcrobatReader)
document with:
pdfDocument = PDDocument.load( is );
add
if( document.isEncrypted() )
{
StandardDecryptionMaterial sdm = new StandardDecryptionMaterial( password );
document.openProtection( sdm ); }
or use loadNonSeq()
PDFTextStripper pdfStripper = new PDFTextStripper(); parsedText =
pdfStripper.getText( pdfDocument );
I get an empty string, and " o.apache.pdfbox.pdfparser.PDFParser - Document is
encrypted" is logged.
When, on the other hand, I do:
ContentHandler handler = new BodyContentHandler( -1 ); ParseContext
context = new ParseContext(); parser = new AutoDetectParser();
context.set( Parser.class, parser );
parser.parse( is, handler, metadata, context ); parsedText =
handler.toString();
I get to see the text/content of the very pdf.
1) What ist he preferred way to extract text from a
pdf("-that-can-be-read-in-AcrobatReader")?
https://svn.apache.org/viewvc/pdfbox/branches/1.8/pdfbox/src/main/java/org/apache/pdfbox/ExtractText.java?view=markup&sortby=date
2) Does the second approach possibly return "more than text"? Blobs? Binary data?
That is TIKA, isn't it?
