Generating a PDF Document From an Adaptive Form Part II

Avatar

Level 3

Here is a sample that renders an adaptive form, loads some information into a hidden field on the form via JSON to use as a timestamp and save location. Once the form submits, it will submit to a custom JSP that saves the data, generates a PDF, and then renders that PDF back to the user so they can sign or print this as a document of record.

Attached is the package. Below is the JSP to handle the custom submit

Dropbox - Return DOR Custom Submit.zip

<%--

    ~ Demo Sample: Gary Thain 01/12/2015

    ~ Returns a PDF DOR from Adaptive Form

    ~ Uses the data on the form to save Original data,

  ~ XDP data and generated PDF to CRX

    ~ Requires:

  a. User Mapper be set

  b. XDP is selected as Document of Record Template

    ~ Still need to add function so user has permissions to node

    ~ where PDF is saved. Currently only working with Admin permissions
