Are you using Application server - Apache - to front Oracle? Have you reverse proxied Application Server? and can you see static pages on it ?? Make sure that the 9iAS is visible and check which port it's on if you're trying the servlet example. Make sure that the connect string in the client points to the reverse proxied port on your ISA server If not The default SQL connection port for Oracle is 1521 I wasn't aware that the standard SQLNET listener would accept HTTP requests, obviously if it does this is the part you'd have to reverse proxy.
