/*
* sdkAddSignature.js
*
*
* Folder Javascript Created by Acrobat SDK.
* This JavaScript sample shows you can programmatically sign a PDF document using
* your digital ID file.
*
* As a sample, this file has included all the digital signature information
* except the path and password for the digital ID file to be used.
* When you are ready to sign a PDF, click the newly added "Add My Signature"
* menu item under the Edit>Acrobat SDK JavaScript menu.
*
* After you input the platform independent path and
* the password through a dialog, the program will create a digital
* signature field in the top-left corner, and sign it with your data. The path
* and password are valid in a Acrobat session, so you can continue to sign more
* documents in the session without the input dialogs.
* If you change the code to specify the path and password for the digital ID
* file to be used in this file, then when you click the menu item, the program will
* go automatically to sign PDFs without UI.
*
* Using the function SetUserPassword() and function SetUserDigitalIDPath() in this
* folder JavaScript code, you can call the JavaScript to quietly sign a PDF from other
* JavaScript code, or from a plug-in or IAC VB or VC program through function
* ExecuteThisScript( ). The VB and C Sample code is attached in end of this file.
*
* A digital signature file ( DrTest.pfx ) is provided with the sample for your test
* To use it, put it in a folder, and specify the proper DIpath ( e.g. /C/DrTest.pfx ).
* Its password is "testpassword".

I placed the code above (I found it the Adobe Acrobat SDK website) in the 'javascipts' folder of my Adobe Reader XI installation folder. The two menus correctly appear under the edit menu. I provide the digital ID path and password but the signature field is blank eventually. I had the same result even when I hard coded the digital ID path and password. Any ideas?
