A ClassNotFoundException means you *do* have a classpath problem,
whether you like it or not. That exception means that the JVM cannot
find the PostgreSQL JDBC driver class, i.e. it's not in the classpath.
Using -jar has the unexpected behaviour that it makes the JVM completely
ignore any CLASSPATH environment setting. So unless projectname.jar
includes the postgresql driver itself, or references it via manifest
Class-Path, this isn't going to work.
Try an explicit classname and classpath (that includes both the driver
jar and projectname.jar) instead of using -jar.
(also, doesn't the win32/dos JVM expect paths in backslash form? you've
got forward slashes above)
