You can do dynamic images in AcroForms using push button appearances - so when
you using iText to modify the form, you can embed the image at that time. Or
if you really wanted something more dynamic, you can also use SOAP calls from
the JavaScript to fetch the image on the fly and assign it to the button.

What do you mean that the image is passed from server? As you are
building/modifying the PDF, right? It's not coming up dynamically when the
document loads - that's not supported any longer (since Acrobat 8, IIRC).
The server is sending base64 encoded string and the requirement is that the
ArcotForm js would assign this encoded string to the image and hence displays
an image at runtime.
You are correct. I followed this approach as reader 8.1(Security update from
adobe) or later doesn't allow the HREF approach.
This is the reason why I want to use XFA form as I was able to achieve runtime
image display by using ImageField not by AcroForm.
You can only have one type of form in a PDF - either AcroForm or XFA, you can
NOT have both. As long as you have XFA, that will cause Acrobat/Reader to
ignore any AcroForms that you have created. In your case, that's the
pushbutton, which is why it doesn't work in #3, because as far as
Acrobat/Reader is concerned, it doesn't exist. If you want to add a button to
your XFA-based form, that's fine too - you just have to do it using lower level
functionality with iText and XFA/XML.
I was just hoping that I can include both the forms as before this xfa approach
the whole application was using iText to create PDF but as you are guiding the
acroform won't be recognized. I was wrong in choosing this approach :(
I was using XFA form to only display the image rest everything is done
through Acroform(iText) .
Can you give any work around or suggestion to achieve this?

Hi All,
Leonard, Thanks for the reply.
Few more additions.
1) I stamped a pushbutton and javascripts invoked on the buttonClick and
documentOpen event (using iText) on a XFA form PDF (created using designer 8.2)
which already had a button and javascript invoked on a button click event.
In the final output :
1. javascript on button(created using Designer) -- working
2. javascript is getting invoked on document open event(this js was added using
iText) -- working
3. javascript on button(created using itext) -- not working
This makes me believe that the js on the button is not getting propely set.
(code in the below mail)
1) Is it not the case?
2) Is this XFA-Acroform apporach not feasible ?
I am deliberately using the XFA form as I wanted to have runtime image(base64
encoded string passed from server) display functionality which I was able to do
using XFA ImageField property.

And you can't mix XFA and AcroForm - which is what you are trying to do (since
PushButton is AcroForm).

If you're using a XFA all you can do is fill the fields, that's all iText
supports.
