    FYI, here is a 3.1 rewritten version of the factory:

    https://svn.apache.org/repos/asf/cayenne/main/trunk/framework/cayenne-jdk1.5-unpublished/src/main/java/org/apache/cayenne/configuration/DBCPDataSourceFactory.java

    It is much cleaner and works off of injectable ResourceService that
    can be defined by the user.

    Will probably rename this attribute to "location" in 3.1, as currently
    the name "datasource" makes no sense, and it initializes the
    "location" property in the Java descriptor class.
