How to read the data from a PDF document into SAP

Hi Everyone,
I am trying to read a PDF document from my desktop and get the data into SAP but i am not getting successful.
I am using the method cl_gui_frontend_services=>gui_upload and passing the filename and type and importing the file length and the data into an internal table.
I tried the file type as ASC but i couldn't get any records in the internal table and the filelength is displayed as 0.
When i tried the file type as BIN, it is giving the short dump. I guess that is because the file i am trying to read is not with the extension BIN.
Please Advice me on this

How to send digital signature from pdf form to fdf file?

Hi...
I already create the pdf form that contain digital signature field using ACROBAT XPRO...and now i would like to send data from pdf form to fdf file.I already manage to send data from other field except the digital signature.How to send the signature digital value to FDF file so that i can display it back to PDF file next time?Can anyone help me...i really need help right now...
tq..

hi....
thanks for replying..
George Johnson wrote:
It did work with earlier versions that did not perform a full save when a signature was applied. Since Acrobat/Reader now do a Save As when a signature is applied, there are no incremental saves to include in the FDF. This can still be useful for forms that haven't been signed, oddly enough, but since you cannot control whether the user performs a full save, it shouldn't be relied on for general use. The big problem is extracting the appended saves from the FDF so you can concatenate it to original document. The FDF Toolkit is the only thing I'm aware of that helps with this.
as u said that,Fdf tool kits can help to solve my problem.Can u send me the sample of code using java so that i can get the value using Fdf Tool kits?
Thanks..

2. Left-click on the Digital Signature field.
3. Click "Verify/Validate Signature".

Unfotunately, this functionality is not supported in current version of Adobe Reader Touch. But, we have noted down your feature request and we might consider it for our future releases.

How do I customize the Digital Signature Reasons dropdown list?

I added a Digital Signature field to a pdf file, then added an Action to the field properties for "Mouse Down" to run a JavaScript.
I am using Acrobat Pro XI.
Here is the Javascript:
// Obtain the signature field object:
var f = this.getField("SigField");
app.alert("ALERT...ALERT...ALERT...")
f.signatureSetSeedValue(
{ reasons: ["Reason1", "Reason2"],
flags: 8
I included the alert statement just to see if the JavaScript is being executed, and it is. The alert is displayed. But, the Reasons field still contains all the default values; it does not contain the specified values ("Reason1", "Reason2"). The name of the digital signature field is "SigField".
Why does this JavaScript not work?
Thank you to anyone who can solve this problem!

It's not clear to me what you're trying to accomplish. If you get rid of your digital ID you will still be prompted to create/add one when you need to sign a form, which you say you still need to do? Do you really just want to e-sign (hand-drawn signature, or stamp) instead of digitally sign? Do the forms you're using have digital signature fields?

Is the digital signature conserved from a signed .docx converted to .pdf ?

Hi!
I would like to know, before purchase or even try Acrobat XI Pro, the folowing question:
If I sign a Microsoft Word (2010) .docx, and then I convert it to Adobe .pdf with Acrobat XI Pro; is my digital signature yet considered always as a signature, or have I to re-sign it in Acrobat ?
(I think it should have to be conserved, to be really a signature, but am not sure about the technical apsects.)
Thank you in advance for your answers.

Ok, Thank you a lot, Test Screen Name !
Yes, I was actually considering the case of a really digital signature (not only a scribble), of course.
So I understand that the digital signature is not conserved as such trough this conversion.
I am french speaking, and I took a moment to understand you second paragraph... which seems to be obvious enought, indeed:
Yes it would be useful to recognize the signature form a Word converted to a Pdf, but it could mean that, if the signature is identified as such - I was no thinking about to get back the signature separately -, a simple conversion of a .docx in .pdf would be an alteration of data integrity (so, not anymore data intergrity could be garanted).
It was clear for me that a signature meant more or less explicitely, that the file could not be modified. But I was very innocent to consider a file only for its "visible characters", rather than the file format, which is also a part of data integrity - of course...
Allright, your answered perfectly to my question, I'll vote for you, as helpful, and correct.
Tank you one more time !
