no, "yarep core" is an API

https://svn.wyona.com/repos/public/yarep/trunk/src/core/java/org/wyona/yarep/core

, which is a bit simpler than JCR, which is also an API.

Jackrabbit is an implementation of JCR.

There exists a yarep-jcr-impl which is using Jackrabbit

https://svn.wyona.com/repos/public/yarep/trunk/src/impl/java/org/wyona/yarep/impl/repo/jcr

rather the opposite

I think you have two choices:

1) Either find a persistance manager for eXist based on JCR for instance 
within the Jackrabbit environment, e.g.

http://yukatan.fi/2007/1.3/org/apache/jackrabbit/core/persistence/xml/XMLPersistenceManager.html


and then you only have to change the configuration

or

2) Develop an eXist implementation for Yarep, similar to

https://svn.wyona.com/repos/public/yarep/trunk/src/impl/java/org/wyona/yarep/impl/repo/xmldb

whereas I don't think this got ever finished, but maybe helps as a start

Cheers
