HCM Processes & Forms : Migrating from JSPs to Web Dynpro for ABAP

Question

We are pretty well invested in HCM Processes and Forms.  We currently use JSP based forms as the UI for our notifications.   We do not, use Adobe Forms.
For a number of reasons, we want to transition to forms based in Web Dynpro for ABAP.
We want to bring a new scenario online using WD4A.  Down the road, weu2019ll very likely transition our old JSPs over to the new methodology as well.  
I would expect that this is pretty well doable.  As part of a proof of concept, we did launch notifications from the web dynpro environment, had them initiate workflow, etc .  Weu2019ve also pulled up our web dynpro app from the UWL and portal.
Has anyone gone through this specific exercise u2013 moving from JSPs to WD4A?  We are particularly interested in where the integration points will be, working with ISR_PROCESS_EVENT, etc.
Your comments, suggestions, references, etc. are welcomed, as well as any discussion you may offer.
Thanksu2026

Answer 1

And along the same lines, any thoughts around which of the following QISRDPROCESS_TYPEs might be a better choice?
Entry Using ITS Service
Entry Using Adobe PDF
We currently use the ITS Service type.  I think this may be our first direction, replacing url links with links to our webdynpro application which woulds need to integrate calls through ISR_PROCESS_EVENT
The Adobe Type seems interesting - Again, we do not, nor will, have Adobe Forms in place for this development.  But, I've read some discussion that folks have enhanced out of actual Adobe Form rendering.
Again, the thoughts of the community are welcomed here.
Thanks...
