JDBC drivers for postgres+classpath for windows

Question

I've written an application for university last year, that connects to a postgres database. It worked perfectly on the Debian, but I'm trying to run it on Windows 2000 now.
I've downloaded the driver http://jdbc.postgresql.org/download/postgresql-8.0-311.jdbc3.jar but now what do I need to write in the "Class.forName(String name)" line , as I've put the jar in c:\ ?
Other question while I'm typing : my other java applications run correctly althought no classpath variable exists in the system. How can I set it easily and how can I add the postgres drivers to it ? ( I know how to under Linux, not windows )

Answer 1

You write Class.forName() using the name of the PostgreSQL driver class, just like you always do.
As far as classpath goes, you set that the same way, too: using the -classpath option when you run java.exe.
You shouldn't have a CLASSPATH variable in the system. One size does not fit all. You should know how to set it every time you compile and run using the -classpath option for javac.exe and java.exe. Read the javadocs for these tools.
