1. It seems your path is lacking the very essential entries %SystemRoot% 
and %SystemRoot%\system32 (SystemRoot is probably C:\Windows or similar) 
You won't get much working on Windows without those entries.
2. You don't need to have the CLASSPATH setting since you run PostgreSQL 
8.0 or later and already have this setting in postgresql.conf
3. Your Java is very old. Consider an upgrade to either the latest 1.4.2 
(1.4.2_08) or to a J2SE 5.0
