Well I do not manage multiple access. This is standalone application so trying to run it twice leads to multiple access, but in such situation JDBC driver forbids to connect for second instance. But I will look at it closer. Maybe preventing running two apps silmutanously would solve all the problems. > What JVM? java.vm.version=1.5.0_06-b05 > what OS?

IDE disk (C:) on one machine. > I was not clear from below, do multiple users use the same database - > possibly trying at the same time? They are not supposed to do, but I check what if running the app multiple times. Thanks.
