Hi srg,
I agree with Daniel, 9iAS is a nightmare to install. It took me three days to install it. However, if you are intending to develop J2EE applications, then you don't need 9iAS at all! You just need OC4J. This is a separate, downloadable ZIP file. It took me only 3 minutes to install, start up and test OC4J!

In answer to your other question, yes, OC4J is the "middle" tier and Oracle 8i is the "data" tier, but actually, a web-based client usually means either JSP or servlets -- not the web-browser.

If you're new to J2EE, let me suggest reading the J2EE specification from SUN:
