I have a requirement to display a static Adobe form. Please help me with this. Is it only possible via, ACF and Adobe document server?
Using ACF & ADS you will be able to create Adobe interactive forms.That is integrating your webdynpro with Adobe using Adobe Interactive form UI element.
There also two scenarios in this offline(static) and online scenario(dynamic).Are you talking about this static scenario?If this so then you have do the configurations settings and install ACF & ADS.
Else if you want call a pdf file from Webdynpro or portal then follow the steps as suggexted by Bhavik.
Static Adobe forms means you don't want to create Adobe forms and no Adobe form design needed.
But you want to display some PDF files on browser right?
So, for that no need to use ACF or ADS. Just, open external window from your application and then specify path to the your PDF file.
