I'm actually on holiday this week, and I don't use IE40 here, so I can't test it. > I was thinking that maybe the postgresql driver doesn't work correctly > when you register it with registerDriver() instead of Class.forName()? Class.forName() simply loads the supplied class into the VM. the postgresql.Driver class does contain a static initializer which registers the driver using registerDriver(). > Have you got JDBC working in IE40? All of my java work is with applications. I haven't tried it with IE40, although I know people have got the driver working with Applets - they haven't told me what browsers they were using.
