Sorry for my ignorance, but what do you mean by the phrase XFA-native APIs?  
Since you use the plural, can you list two such APIs?

  Acrobat 8.1 (and equivalent version of LiveCycle Designer) NO LONGER SUPPORTS 
the mirroring of XFA fields into AcroFields in dynamic documents - which is 
why you can no longer use the method you've chosen on dynamic documents.


  You need to switch to using the XFA-native APIs.

Paulo,
Thanks for your help.  Rather than clog the mailboxes of every iText 
mailing list user I put a sample at 
http://www.xigole.com/scott/itext/pdf1.7issue.zip to download (1.4Mb).  This 
file contains roughly the source I'm using and shows that only Acrobat 8 
dynamic files have a problem but Acrobat 7 static and dynamic and Acrobat 8 
static work.

The file contains a sample XDP (my source data), 4 PDF's (7 and 8 static 
and dynamic), the source code (single Java file) and a build file.  Once built 
run either the batch or shell script to generate 4 different PDF's from the 
source PDF's.  If there is anything I can do to assist this effort I would be 
happy to do so.  I am reading the generated PDF with Adobe Acrobat 8.1.1 
Professional.

Thanks again for any help.

Subject: [iText-questions] Pdf 1.7 and merging XFA data

Hello,
I've got a version 1.7 PDF that I'm trying to get the 
AcroFields out of, 
merge XFA data into it, and save it.  If I save the PDF as an 
Acrobat 7 
(static or dynamic) PDF in LiveCycle Designer 8.0 I can merge 
fine.  If 
I save it as an Acrobat 8 PDF the result from 
PdfStamper.getAcroFields() 
seems to be empty and my resulting PDF does not have the any of the 
fields filled in.

Is this an existing limitation of iText and PDF version 1.7 or should 
the code look different?  Thanks very much for any help.

The code:

// inputDataElement is the xfa:data element from an existing XDP file

PdfReader inputReader = new PdfReader( input.pdf );

File tempPdfFile = File.createTempFile( sd, .pdf );
FileOutputStream tempPdfOutputStream = new FileOutputStream( 
tempPdfFile );
PdfStamper pdfStamper = new PdfStamper( inputReader, 
tempPdfOutputStream );

AcroFields fields = pdfStamper.getAcroFields();
fields.mergeXfaData( inputDataElement );

pdfStamper.close();
tempPdfOutputStream.close();

[iText-questions] How to change a PDF but preserve the rights

2007-12-02 Thread Samuel B. Quiring 
I have a PDF containing an XFA form; isXfaPresent() == true.  The PDF was 
authored so that it can be opened in Adobe Reader, fields in the form can be 
filled, and the form can be saved by Reader to the file system.

Using iText I have read in the PDF, obtained the XfaForm, changed values in the 
XML Document, and written a new PDF to the file system.

The PDF I write out contains the values I put into the XML, but the rights to 
save the PDF from Reader have been lost.  Is this expected?  Other features of 
the original PDF are also lost in the newly-written PDF.

I wrote the changed PDF to a new file.  If this is the reason the save rights 
were lost, is there a way I can modify the existing PDF in place so that the 
rights to save the file from Adobe Reader are maintained?

[iText-questions] Invalid signature file digest for Manifest main attributes (2.0.7)

2007-12-08 Thread Samuel B. Quiring 
I have a small test program that uses iText.  It's been working fine for weeks. 
 Today I downloaded itext-2.0.7.jar and replaced itext-2.0.6.jar.  I rebuilt - 
no problems.  When I tried to execute, I received this stack dump shown below.  
Any ideas?

I should probably mention that my build.xml file builds a single .jar from my 
simple test program and the itext-2.0.7.jar.  To do this it unzips all the .jar 
files my code depends on (only itext-2.0.7.jar in this case) and then jars 
everything up into one big .jar with my main class called out in the manifest.

I invoke my test program like this:java -jar test.jar

Starting with 2.0.7, the official iText jar file is now signed by Bruno.
It seems that your problem comes from the repackaging of parts of the
official jar file done during your build process.

As a first step, you could try to run you application using your own
classes and the official jar file to see if it works in that situation.

If that works then, you'll need to have a closer look at how you're
repackaging the classes. It's probably best to keep the official jar as
is and just add it as a dependency in the manifest file for your
test.jar file.

Re: [iText-questions] How to change a PDF but preserve the rights

2008-02-04 Thread Samuel B. Quiring 
Leonard,

Are you sure?  I have tried a few variations and I have not been able to get 
anything to work.  I now have a simple identity() routine that changes nothing. 
 The incoming PDF has rights that lets Reader save filled-in data.  The 
resulting PDF has the rights removed.  As far as I can tell, I changed nothing. 
 What did I do wrong?  Here is the code:

public static void identity()
{
PdfReader reader = new PdfReader(C:/tmp/niceForm.pdf);
reader.setAppendable(true);
XfaForm xfaForm = new XfaForm(reader);
FileOutputStream pdfOutput = new FileOutputStream(C:/tmp/newFormOut.pdf);
PdfStamper stamper = new PdfStamper(reader, pdfOutput);

xfaForm.setXfa(stamper.getWriter());
stamper.close();
pdfOutput.close();
reader.close();
}

  It _IS_ possible to fill in a PDF that has been Reader Enabled w/o 
violating the rights - but it MUST be done in a very specific fashion using 
append mode on the source PDF AND only modifying a limited number of objects

  So yes, if you are going to create a whole new PDF - you'll break the Reader

It can't. 

If you make ANY changes to the PDF you will break the rights. It's specifically 
designed this way to detect tampering.

The only choice you have, if you wish to distribute a file with Reader 
Enablement is to purchase Adobe LiveCycle ES and have it
process your document AFTER you do whatever dynamic functionality you wish.

I wrote the changed PDF to a new file. If this is the reason the save rights 
were lost, is there a way I can modify the existing PDF
in place so that the rights to save the file from Adobe Reader are maintained?

[iText-questions] Can iText add an attachment to an XFA-style PDF?

2008-02-08 Thread Samuel B. Quiring 
Greetings,
 
I have a PDF that contains Javascript with this pattern:
 
 var oDoc = event.target;
 oDoc.importDataObject(localAttachmentName);
 
The importDataObject method adds an attachment to the
PDF file.  The other related pattern is:
 
  var oDoc = event.target;
  var oAttachments = oDoc.dataObjects;
  . . .
  for(var i = 0; i  oAttachments.length; i++) {
var attMent = oAttachments[i];
recordAttachment(attMent.name, attMent.path);
  }
 
Is there any way in iText to add an attachment to a PDF
file like importDataObject() does?  In particular I need the
attachment to appear on the dataObjects list.
 
-Sam

[iText-questions] Need help Flattening an XFA PDF

2008-02-26 Thread Samuel B. Quiring 
I need help flattening a PDF file where isXfaPresent() is true.  I am
trying to use the following routine.  It works fine for older PDF forms.
When isXfaPresent() is true this routine creates the new file without
error, but Adobe Reader claims I need a newer version of Adobe
Reader to read the result.
 
function void flattener(String filename)
{
PdfReader reader = new PdfReader(filename);
FileOutputStream pdfOutput;

String outputFile = filename.replace(.pdf, _flat.pdf);
pdfOutput = new FileOutputStream(outputFile);

PdfStamper stamper = new PdfStamper(reader, pdfOutput);
stamper.setFormFlattening(true);
stamper.close();
pdfOutput.close();
reader.close();
}
