LiveCycle Forms Design using Java API

Do you mean "Java" running on the server? Or JavaScript, which is the internal programming language for implementing interactive features on LiveCycle forms? What kinds of changes?

I am using Java on the server side. I want to add Javascript functions to the forms using APIs.
Is that possible ?

Thanks,

Yes, but it's not easy. There are lots of 3rd party Programming tools for manipulating PDFs and AcroForms, but only Adobe has programming tools for manipulating LiveCycle forms. But this doesn't mean it can't be done.

There is a free Java Object Library for PDF called iText. This is a really well thought out and maintained SDK. It allows for easy to write, simple manipulations of PDF at a high level. But if you know what you are doing, you can drill down through the Java Objects to the lowest level of the PDF structure. You could use this library to access and modify the XDP in the LiveCycle PDF.

Alternatively, you can modify a LiveCycle form by importing an XDP file. I don't know if the XDP can be used to add a script to the form template, because I haven't tried it. But if this does work it would be much, much easier than using iText.
