I have two programs:
one which I run via : java JavaProgram
which connects to the Postgresql database, and puts stuff in, etc.
one which I run via a webserver - an applet, which is called in an html
document, and attempts to access a Postgresql database.
Both programs load the driver via "Class.forName("postgresql.Driver")",
and use DriverManager.getConnection - however, the first one, the
application, apparently finds the postgresql.Driver via its CLASSPATH.
The second one, the applet, does not HAVE a CLASSPATH because it is
invoked by the web server, and therefore returns "cannot find suitable
driver".
I have put postgresql.jar (the JDBC driver) in the directory that the
applet is being executed, but it is still not found.
There must be a way to use a JDBC driver with applets, right?
Unfortunately, I don't know how to which is environment variable
"independent"...anyone?

The jar file must be defined in the <applet> tag. Now most browsers don't
support multiple archives, so there are two way around this:
1) unpack postgresql.jar, so that the postgres directory is in the same
directory as your applet.
2) unpack as in (1), but then repack the driver and your applet into a new
.jar file, and refer that in the <applet> tag.

Applets don't have access to environment variables.
