Default Schema for DefaultConnectionIdentifier

[aw]

I specify my database by specifying a jndiName for
DefaultConnectionIdentifier:

DefaultConnectionIdentifier.jndiName = "jdbc/myOracleDb"

I really need to specify a default schema too... (For Hibernate, I
would specify this in persistence.xml.) Is there a way to specify a
default schema?

I found DB.globalDefaultSchemaName, but the Schemifier is still
breaking:

OK, I'm not 100% sure what DB.globalDefaultSchemaName is supposed to
do because specifying it broke Schemifier as well as my queries.
Certainly, it sounded like what I needed, but doesn't do what I
expected...

Basically, I am looking for the Lift equivalent to:
hibernate.default_schema
