Yeah, I noticed that my answer was only half of what you'd need and 
wondered why you didn't ask. Here's some code to create an empty 
signature field. Tell me if it works for you. If it does, then I should 
add it to our example collection.


         PDSignatureField sigField = new PDSignatureField(acroForm);
         PDAnnotationWidget widget = sigField.getWidgets().get(0);
         PDRectangle rect = new PDRectangle(50, 650, 200, 50);
         widget.setRectangle(rect);
         widget.setPage(page);
         page.getAnnotations().add(widget);

I tried that code in the CreateSimpleForm example. Here's the full code, 
remove the parts about the other field (textbox):
