No. JDBC is described in version 1.4 J2EE.2.6.6. Also, JNDI is
J2EE.2.6.8. Both are distributed as enterprise features in J2SE, though,
along with a couple of other J2EE features as well.

So why do you absolutely not want to use a connection pool for this
purpose? You'll have the opportunity to let each user have more than one
connection at a time, the pool will handle the connection for you
automatically, you won't have to re-connect if the connection closes for
you and so on. Sounds much better to me ... writing code to handle such
standard stuff is just a waste and opens up for nasty bugs nobody really
needs (unless those who write debuggers, ofcourse :-)
