I can't connect

Hi,

I installed debian 2.2r2 with _all_ the postgres-packages,  I created a database and via psql I can do whatever I want
withthe DB. Now I'm trying to make a connection via a Java-program. I downloaded the jdbc-6.5-1.2.jar file and renamed
itto jdbc.jar and moved it to ~/jdk1.3/lib, set the CLASSPATH to ~/jdk1.3/lib and used a program, found in the
Deitel&DeitelJava book. 
After that, I tried to make a connection to the database I created (testing) and I keep getting error-messages.

Can someone help me with this? I'm trying for 3 days now and still no luck.

Thanks,
Bart
