That's how jdbc works - you load the driver by name.  The jdbc stuff in libgcj
takes care of everything else...

java.sql.DriverManager.registerDriver (Class.forName
("org.postgresql.Driver").newInstance());

I think the problem here is that you've chosen a poor name for the driver
library.  Try calling it `lib-org-postgresql.so' instead of `libjdbc.so'.
That's the name libgcj needs in order to find the driver class.  strace your
application to see the various combinations of names libgcj is attempting.

Better yet - simply download and build the postgresql jdbc driver from rhug...
