Auto merge of multiple configurations is on the TODO lист, but don't  
have ит currently. So you'll have to do it yourself. E.g. exclude  
cayenne.xml from frameworkUsingCayenne.jar, and then manually add  
shared datamaps to /WEB-INF/classes/cayenne.xml.

Any dynamic / non-standard DataSource configuration is done by setting  
a custom DataSourceFactory class in the Modeler for your DataNode.  
Here is the interface you need ti implement:

http://cayenne.apache.org/doc/api/org/apache/cayenne/conf/DataSourceFactory.html

Hope this helps.
