Hi Prashant,
Note that Cayenne user support is done via the mailing list, as it
allows us to better share the community knowledge. I am ccy'ing the
question to the list. Please feel free to continue this discussion on

Yes you can - this is just XML. Here is one possible scenario that
uses Cayenne to bootstrap Cayenne:
* Create a separate Cayenne project to map you "bootstrap" tables
that store the Cayenne metadata.
* Create your own Configuration subclass that internally instantiates
a temporary throwaway Configuration just to read the metadata.
Feel free to ask if you get stuck with the API.
Cheers,
Andrus
