I am using JBoss 3.01 and JDK 1.3.1_04. I do have servlets connecting to Firebird with straight JDBC connections, so I am inclined to think the problem is either with my setup in the attached configs or in the driver...

<!--FBManager can be used to create and drop databases.
Drop is especially useful during testing, since it
assures a clean start next time. -->
