Well, you could hack up the code to put it there but it still won't work
- DataSource is not serializable.

Weblogic's datasource implementation is an RMI server object. Just
because they do this doesn't make it a good idea - think about it -
You're in one process, the datasource is in another, and the database in
a third. That means that if you use this feature, your doubling the
number of times you go through the OS network stack, doubling the number
of times your poor data gets bounced around. This is just from a
physical architecture point of view - from a logical point of view how
do you intend to maintain a system where data access can happen from any
random bit of code in any layer? How many classes will you need to touch
when your schema changes?
