Is it possible to use Dynamic Data with a DB2 Database from a JD Edwards system?  If so, where is the best place to get information on this?

supports Oracle and others, but I don't see DB2. See Dynamic Data FAQ  Q: Can Dynamic Data use a data model generated by a 3rd party O/RM tool?

You would need to use Entity Framwork for Dynamic Data see the supported providers here:

Thanks for list.  It does support DB2.  I assume I will have to research how to use this with the 3rd party.  Do you have a recommendation on where to start this research?

I assume that if you can create an ebmx file for Entity Framework to DB2 then it will just work with Dynamic Data
