Change the above to:

and let me know what exception is being thrown.

I haven't been able to find it either.

This sounds like IE40 doesn't like JDBC... I'm actually on holiday this
week, and I don't use IE40 here, so I can't test it.

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().

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.
I assume it was both Netscape and IE
