Postgres jdbc transactions

Hi,

I am having a hard time to manage transactions with Postgres 8.3.

I am using latest Postgres jdbc driver and apached dbutils library.
After getting a connexion I am trying to set Connection objet to autocommit "false" but I get an error message from DB saying that setting autocommit to off is no longer supported.
Therefore, when I'm trying to call "rollcack" at the en d of my code, I am rejected sayning that my DB is in autocommit true.
Can you tell me what I am doing wrong or which library I should use ? 
so far I have found no example   on the web...

Thanks
O.

It's hard to point out what you are doing wrong if you don't show exactly what you are doing (and the error message). A
vaguedescription doesn't cut it.

Show your code. I'm suspecting the same problem as
http://postgresql.1045698.n5.nabble.com/SET-AUTOCOMMIT-TO-OFF-no-longer-supported-td2169957.html
quoting the glorious Kris:

  Check your classpath.  I'd bet you've got two versions of the driver in
  there.  Try adding this line somewhere in your app.

  org.postgresql.util.PSQLDriverVersion.main(null);

  It will print where it finds the driver on stdout.

(an old version of the driver biting you)
