Just some thoughts : AFAIK, we need JDBC wrappers to redefine methods 
that are common to both JDBC 2 and 3, and we left untouched JDBC 3 method.

So, can't a simple solution be an abstract JDBC wrapper that implements 
all of JDBC3 and which is required (through its build.xml) to be 
compiled with a JDK 1.4 ?

A JDK 1.3 should not complain about unkown methods as long as they're 
not used, allowing us to write concrete wrappers that would work equally 
well in 1.3 and 1.4.
