Hi are you using pg73jdbc3.jar, I had a similar problem and when I switched back to the previous version driver it all started working fine.
May be you want to try switching to the previous version of the JDBC driver and see if it works
Could you tell me what version of driver you using and where I cand find it.
OK!
Thank you all for your answers, problem was realy in driver. After I've started to use previous driver I've got success with this stuf. Uhh, it was terrible to find such kind of problem.
Oleg.
