First of all great solution.
I have problem with this code and hebrew (and i think that the same problem is for pdf in Arabic).
The text appear to be mirrored (from left to right instead of from right to left).
Does anybody have a solution?
Thanks in advance

First of all, thank you for posting this article! It's exactly what I needed.
Just wanted to let you know that PDFBox-0.7.3 already has a tool for extracting text (extracttext.exe) and another for extracting images (extractimages.exe). Here's usage information for the former:
C:\PDFBox-0.7.3\bin>extracttext
Usage: java org.pdfbox.ExtractText [OPTIONS] <PDF file> [Text File]
-password <password> Password to decrypt document
-encoding <output encoding> (ISO-8859-1,UTF-16BE,UTF-16LE,...)
-console Send text to console instead of file
-html Output in HTML format instead of raw text
-sort Sort the text before writing
-startPage <number> The first page to start extraction(1 based)
-endPage <number> The last page to extract(inclusive)
<PDF file> The PDF document to use
[Text File] The file to write the text to
I don't know if those tools were available when you posted the article. Thank you once again for taking the time to share your findings with the community.

Hello,
I tried following statements, it is compiling successfully. No error is occurring but document is not getting loaded at first statement.
PDDocument doc = PDDocument.load(SourceFile);
PDFTextStripper stripper = new PDFTextStripper();
return stripper.getText(doc);
I have given valid path, if I give wrong path, it throws error. What can be wrong? The reason I am saying doc object is not getting filled with file is, I am getting "Object reference not set to an instance of an object." error on line 3rd ( return stripper.getText(doc)

Hi
I have tried to use:
PDFTextStripper but it is impossible to parse the text since the table cells are not delimited with any character.
PDFStreamParser but i failed to understand how to navigate through the result . see code bellow:
...
page = CType(allPages.get(pindex), PDPage)
contents = page.getContents()
Dim parser As org.pdfbox.pdfparser.PDFStreamParser = New org.pdfbox.pdfparser.PDFStreamParser(contents.getStream())
parser.parse()
Dim tokens As java.util.List = parser.getTokens()
For tokenI As Integer = 0 To tokens.size()
Console.WriteLine(String.Format(" Token {0}/{1}", tokenI, tokens.size))
Next
1. Is there a way to identify a table in PDF file ?
2. What are the alternatives for extracting tables data only using pdfBox ?
3. How is it possible to step through a table ?
Regards,
Hanan

Initally I used pdfBox with Vb.Net and it is working smoothly.
But when I ported code to C# with this code try catch with WrappedIOException (org.pdfbox.exceptions.WrappedIOException)
is required and always WrappedIOException is thrown for any pdf file;
and e.getMessage() is "The signature is incorrect."
What could be wrong? same time vb.net code is working without any try catch.
I'm using PDFBox-0.7.3
Visual C# 2008 Express edition & VB.Net 2008 Express edition

Why is it you all are able to load a PDFBox-0.7.x.dll into the GAC? Are you compiling your own PDFBox-0.7.x.dll with a .snk? If so, from what PDFBox-0.7.x.dll source? If not, where can I locate, for download, a strongly named PDFBox-0.7.[2 or 3 or whatever].dll?
I've tried PDFBox versions .2 and .3 and my gacutil.exe fails on adding either assembly to the cache.
But you guys appear to have no problem with that. I'm using .NET SDK v2.0.
BTW, is anybody even using the GAC? Or are you allowed to just drop these DLLs directly into a directory path and start compiling the PDF sample?
Thanks for any replies.
