This just applies to the <sql:setDataSource> tag, which is intended mostly
for prototypes and small applications.  But you can make any DataSource
available in any of the scopes and then refer to it directly using the
expression language.  (Or see chapter 14 of "JSTL in Action" to see how to
set up a default DataSource object for all of your <sql:*> tags.)
