Save typed-in content with Adobe Reader

by Fhomasp :: Rate this Message:

Reply to Author | View Threaded | Show Only this Message

Hey,

I built a DocumentBuilder which builds Pdf Documents using iText.  My idea was to couple setter fields from a Bean receiving form data from a JSF page to the documentbuilder class.  This allows me to dynamically produce Pdf files, however one of the requirements is for the user to fill in missing, incomplete or incorrect Data in the generated pdf document itself, online.

Someone told me to perhaps use rights in the document.  I have the book and I found a few possibilities for setting rights to a document, either by the PdfEncryption class or using a stamper but I'm unsure wheather this will produce the desired effect.  Something tells me that I will need the Adobe Acrobat full version for this.

Or I could create a template document but that would destroy the idea of dynamically generating documents depending on the fields in the online form.

Any advice is greatly appreciated.

Cheers,
Thomas

ps. Nice framework :)

If the user is only going to be posting the data back to a server -  
then you don't need to add any special rights to the PDF.  Reader can  
happily post data...

However, if you wish the user to actually save the PDF to their local  
disk, then you do indeed need Acrobat (or LiveCycle Reader  
Extensions) to enable that option.

OK, but then they have to submit that data to a server.
Note that the EULA of Adobe Reader forbids submission to
the localhost. PDF forms that are filled out can't be
saved locally unless the PDF is Reader Enabled.

That's about setting permissions, not about Reader Enabling.
Technically Reader enabling is similar to signing: the
document is signed with a private key from Adobe and as
a result the end user has extra rights (for instance to
save the filled out PDF locally).

> Something tells me that I will need the Adobe

As the signing is done with a private key from Adobe,
you will need Adobe software. Your instinct was right:
you won't find any other software that allows you to
'reader enable' a PDF.

I don't understand the above sentences, but as far as
I understand it, the problem can easily be solved by
letting the user submit the data to the server.

Thank you all for the quick responses.

I'll clarify the situation.

Somehow I need to figure out a solution for the following situation.

A User who requires assistance needs to fill in a form but is unsure of all of the required information.  
For this matter there is an online form which will already contain info from our database.  However the user needs this form to be portable or at least travel over an offline environment.
Later on, the user needs to be able to submit the PDF document online.
So basically there is an offline time gap between the created pdf document and the submit time of this pdf document.

I was thinking about an XFA form with reader enable but when I add a field to the original JSF form I need to adjust the XFA template.
Or, more on the line of what I'm currently thinking, which goes a little something like this:

I have a copy and license of Adobe acrobat 8 Pro.  I create a Root document with "Reader enable", import this in the Java application using a stamper.  
Will I be able to add any field, table or radiobutton in the future and allow the user to save the document with the new fields set on the document?

Sorry if this is a bit weird or strange, know that I don't do that on purpose :)

        OK, so this is a common situation, but one not solvable by iText  
alone..

        Unless you really want/need XFA - I would stick with standard  
AcroForms.  (regardless of any other choice you make)

        As soon as you start playing with that form with iText, you will  
break the "enablement" - so that's a non-starter.

        That means you have two choices
1) You purchase Adobe LiveCycle Reader Extension Server and then that  
"enables" the document after you've used iText to apply the content.
2) You don't use iText at all - and instead use FDF files in  
conjunction with your "Reader Enabled by Acrobat" file.

In the first choise, and because you would have bought Reader Extensions, you could then use XPAAJ instead of iText, because merging (only) data with XPAAJ should not take the Reader enabled "thing" from your form. This would improve your solution because you would need to send only one time the pdf template to Reader Extensions.
 
Off course iText is more powerful than XPAAJ, but it doesn´t seems to be the best solution in this scenario.

1. Create the *complete* AcroForm first, including all contemplated form fields and "submit" actions.
2. Use Acrobat 8 to make the Acroform Reader-Enabled.

The user will then be able to work the AcroForm offline and later, submit the filled AcroForm. Note that the submit action requires that the AcroForm is displayed in the browser, with Reader as the plugin, at the time the submit action is employed. This has worked for me. YMMV.

That is strange because I have in my hands a recent (6 months old, maybe) recommendation from Adobe, and they told us to use XPAAJ.

Right, thanks for clearing that up.

So after creating the AcroForm template, which I can do programatically or by any other means, it doesn't really matter.  Perhaps creating it programatically is the best solution because I can name the fields myself and be able to recognize them better.

I do have an additional question.

After I created the template and made it Reader Enabled, can I use a PdfStamper or PdfWriter to modify the textfields without breaking the Reader Enable?

Creating the form with iText is especially attractive if the AcroForm has fields or groups of fields that are repetitive, such as in a lineage society application form. I have one Acroform, where all of the genealogical data fields

AFAIK, you should be able to "fill" the form fields with data without breaking the form. Any changes to the AcroForm, other than that should break it.

I don't know who made that recommendation here - but I can vouch for the fact that XPAAJ is dead.  I was involved in the discussions to kill it.

In the first choise, and because you would have bought Reader Extensions, you could then use XPAAJ instead of iText, because merging (only) data with XPAAJ should not take the Reader enabled "thing" from your form. This would improve your solution because you would need to send only one time the pdf template to Reader Extensions.
 
Off course iText is more powerful than XPAAJ, but it doesn´t seems to be the best solution in this scenario.

        Nope :(.

        IF and ONLY IF you write the changes out as an "update" instead of a  
"replacement" AND you only change the things that are allowed...
