Oracle Database Discussions

Hi,
I am trying to Install Oracle 10g release 2(10.2.0.1.0) on Windows XP Professional(SP2).
Existing environment:
1. Java(SDK & Runtime Environment) 6 update 1.
2. Configured Eclipse.

The installed procedure:
1. Downloaded "10201_database_win32.zip" from Oracle website.
2. Unzip it and run setup.exe
3. It gives an error like below :
"javaw.exe - Entry Point Not Found"
"The procedure entry point longjmp could not be located in the dynnamik link library orauts.dll."

Installation completed(forcefully) without the below.
1. Oracle Net Configuration Assistant (Failed)
2. Oracle Database Configuration Assistant (Failed).
and in services: "No Oracle process exist".

I tried the below:
A. Change the environment variables (remove ORACLE_HOME/ORACLE_SID etc)
B. 2 to 5 times un-install oracle(including registry, directory etc) and install.
C. Uninstall Java SDK & Runtime Env. Then install Oracle.
D. Installing Personal edition, Enterprise edition etc etc.
E. Checked the orauts.dll in 3 places(i. BIN ii. out/bin iii. oui/lib/win32
F. Copied the orauts.dll to system32 directory.

What ever I do the above appers all the time and installation is incomplete.

Due to this problem I couldn't move further, please do help me in solving this.

Thanks a lot in advance.
