Hi Bruno,
Finally, here is my scenario.
- I have a template with two pages. On first page, I have an acro field for
an image, on the second I have three acro fields.
- I used your example (BatchFill.java) and able to write document and fill
acro fields on both pages.
- I am pasting my programme here, when I run this programme, the page 1
and page 2 are getting included in single page. How can we prevent that?
Meantime, I even tried to move to next page also, because if I say,
System.out.println("page No: " + writer.getPageNumber()); its always
showing page 1.
- I read your article and not able to understand, probably you are using
stamp, I don't want to use it since my file size needs to be limited.
I hope you understand my problem.
