JDBC for 7.2.x

Hi

I upgraded postgres from 7.1.3 to 7.2.1 and now to 7.2.2 version....
All works ok except I cannot obtain LO data in servlet with new version of
JDBC. It just return OID of LO instead of data.

I work now with posgres using jdbc7.1-1.3.jar file. I think it's wrong but
it only file working with Large Objects well....

How I can upgrade to correct version of JDBC?

I tried pgjdbc2.jar also (from jdbc.postgresql.org) - same problem.

Thanks.
Alexander
