Hi,
I have given 2 weeks to solve JRE installation problem with Oracle 9i on Windows XP Prof Sp2.
1- Create a folder in and assign this name C:\Ora9i and create Disk1, Disk2, Disk3 folders into it. Extract zip files into related folders.(You understand this anyway!)
2- Download and istall "j2re-1_3_1_02-win"
https://ny168amicasb.cpmc.columbia.edu/plugins/jre/1_3/
3- Download and install "jre-1_1_8_010-windows-i586-i"
http://java.sun.com/products/archive/jdk/1.1.8_010/jre/
4- My computer(right click), Properties, Advanced, Environment Variables.
There is a "Path" variable and its value in "System Variables" section.
5- Add this line into value of "Path" (don't delete anything);
C:\Program Files\JavaSoft\JRE\1.3.1_02\bin;C:\Ora9i\disk1\stage\Components\oracle.swd.jre\1.3.1.1.0a\1\DataFiles\Expanded\bin;C:\Program Files\JavaSoft\JRE\1.1\bin
6- Restart you computer.
7- Start installation process in Autorun folder of Disk1.
8- You shouldn't have any problem after all.
9- I did it at the end of the fight with this.
10- Good luck
Regards
