Hello,
I'm not using JDE but we are using Formscape Version 3 and all our forms have been designed to be emailed as PDFs, if not now the hooks are there to email.
It's fairly trivial to set it up in V3. The object is straight forward taking the email server's name, to address, from address (which does not need to be a valid email address at all I found), then subject, body and any attachments all as child objects of the email object.
There was one issue with formscape runtime server being on Win2003 that formscape has a fix for (2003 lacking a certain DLL). Other than that it is really easy.
We've developed forms that generate text reports as the email body. I have also set up error branches that email me when problems occur.
Hope it works out for you.
Thanks,
Michael Sperl
