I think you should have the jdbc driver  in your
classpath.

About your URL Prefix:
jdbc:oracle:thin@server:1521:WHTE
Your database  name is "safwhte" but you use "WHTE" as
the name of your database.
jdbc:oracle:thin@server:1521:safwhte

Shouldn't you have a colon after thin?
jdbc:oracle:thin:@

A question: doe's WebSphere 3.5 support oracle  8.05 or
higher?
