Yes, hostname.com *IS* a valid host, and it DOES exist.
I use:
-- snip --
    postgresql.Driver driver = new postgresql.Driver();
    try {
	DriverManager.registerDriver(driver);
    }
    catch(Exception e) {
      textStatus.setText(e.toString());
    }
-- snip --
to register the driver.

This part works though.  The problem is when I try to make
a connection:
    conn = DriverManager.getConnection(connectionURL);

This generate an exception as I mentioned above, and returns
"cannot access <hostname>".  I searched through the java-classes,
but I didn't find this string *anywhere*.  That's why I wondered
where it came from.  (it's not an standard hostnotfound exception)

However, the strange part is, that this *ONLY* happen when I run 
my program as an Applet in IE40.  It *DOES* work perfect if I run
the program as an application or in hotjava.  I.e. It only seem
to happen in MSIE40.  In other words, I know that the JDBCURL is
right and that access-lists are correct.

I was thinking that maybe the postgresql driver doesn't work correctly
when you register it with registerDriver() instead of Class.forName()?

Have you got JDBC working in IE40?
