JDBC postgresql.Driver

Hello,

I'm trying out an O'Reilly java example on my Windows95 machine. I have
downloaded the precompiled version of postgresql.jar. But for some reason
the the complier doesn't recongize that the postgresql driver is there.

---
C:\WINDOWS\DESKTOP>javac -classpath c:\windows\desktop\postgresql.jar
ExecuteSQL
.java
ExecuteSQL.java:33: Undefined variable or class name: postgresql
Class.forName(postgresql.Driver);
^
1 error
---

or where I complie woth out specificing the driver I get this:

---
C:\WINDOWS\DESKTOP>java ExecuteSQL -d postgresql.Driver
jdbc:postgresql://beta.pen.k12.or.us/os98

java.lang.ClassNotFoundException: postgresql.Driver
Usage: java ExecuteSQL [-d <driver>] [-u <user>] [-p <password>] <database URL>
---

Should I being calling the driver by a different name? I'm not sure what
is going on here?
