I cann't get it installed because I don't have the installation key.

When I use the key that above link gives, it doesn't work. Anyone has installed recently? It's Oracle9i Developer Suite, release 2. I think they stopped supporting this, but there's gotta be someway to install.

And I cann't use 10g because I already have 9i Enterprise Version on my computer.

Goto oracle.com/downloads and find oracle 9i developer suite. Then download and install it. You don't need a license for using it just for development but you do have if you go to production which you don't care about now i guess.

MohanB, thanks for your reply, but I don't think i can still download 9i since they don't support 9i anymore. One question, i have 9i Oracle database Enterprise version, but if i use 10g developer suit, will it handle 9iOracle? Please.. sajha IT gurus!! Wake up! Help me!

Who told you that they don't support 9i, they even support 6i and will continue to support. Yes, definately 10g DS can run on 9i database. I am having a feeling that you are just starting in Oracle. Please read some books or goto http://www.otn.oracle.com and update yourself. Good luck.
