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)
