> Cayenne up to 3.0 supported emulation of JNDI DataSource for local work based on the
Modeler preferences (aka "JNDI hack"):
> In 3.1, Modeler preferences are implemented differently, using "java.util.prefs", and
instead of porting the JNDI hack to the new mechanism, I will provide a more sensible replacement,
based on JVM startup properties. The name of the new DS factory  will be PropertyDataSourceFactory.
PropertyDataSourceFactory will be used to override not only JNDI DataSources, but any other
DataSource configured in the Modeler.
> The property names will be the same as the properties used in unit testing:
> But with a few changes:
> * we'll support  dot notation, not capitalized notation. Dot notation is traditional
Java property naming approach, while capitalized notation was introduced to be able to run
unit tests on Hudson that breaks on dot notation.
> * property names will allow an (optional) suffix with <domain_name>.<node_name>
to make sure multiple connections can be specified per JVM. 
> * cayenne.jdbc.driver[.domain_name.node_name]
> * cayenne.jdbc.url[.domain_name.node_name]
> * cayenne.adapter[.domain_name.node_name]
> * cayenne.jdbc.username[.domain_name.node_name]
> * cayenne.jdbc.password[.domain_name.node_name]
> * cayenne.jdbc.min.connections[.domain_name.node_name]
> * cayenne.jdbc.max.conections[.domain_name.node_name]
> At the minimum, cayenne.jdbc.url and cayenne.jdbc.driver must be present for the overrides
to kick in.
