Unable to install Oraclei 8.1.7 on P4 machine

Question

I am unable to install the above version of Oracle on a IBM P4 machine with 256 MB RAM.
Got the following message while installing:
JRE was not found at:
d:\software\Oracle8i\stage\components\Oracle.swd.jre/1.1.7.24/1/Datafiles/Expanded/jre\win32\bin\jrew.exe
Install jre 1.1.7 or above and continue.
After getting the above message, I installed jre 1.1.8_09.
Inspite of this, the installation is not commencing.
The documentation is silent of this. However, it does mention that that it may possibly happen with a Novell Netware system due to the filenames being restricted to 8 characters.
I did try this out to and named the installation directory of jre with 8 characters. But the problem still persists.
Looking forward to a solution from some Oracle gurus.
Thanks in advance.

Workaround
~~~~~~~~~~
Not only will OUI be affected by this bug, most of the post-install
configuration tools will also be affected. Running these tools with "-nojit"
specified will avoid the hang, but it is not simple to specify "-nojit" for
some of the products.
The following workaround works for the Windows operating system:
a. Copy only the install directory from the CD to the hard disk ,say, e:\temp.
b. Open oraparam.ini and make the following modifications (Assuming CD
drive is f:)
* Change the "SOURCE=" line to use the full path to the CD instead of a
relative path. (i.e., SOURCE=f:\stage\products.jar)
* Change the "JRE_LOCATION" line to use the full path to the CD instead of a
relative path. (i.e.,
JRE_LOCATION=f:\stage\Components\oracle\swd\jre\1.1.7\1\DataFiles\Expanded)
* Change the "OUI_LOCATION" line to use the full path to the CD instead of a
relative path. (i.e.,
OUI_LOCATION=f:\stage\Components\oracle\swd\oui\1.6.0.9.0\1\DataFiles\Expanded
* Change the "JRE_MEMORY_OPTIONS" line to add "-nojit" as the first argument.
(i.e., JRE_MEMORY_OPTIONS=-nojit -ms16m -mx32m)
^^^^^^
* Other entries should remain the same
c. Launch setup.exe from the temporary location on your hard drive (i.e.
e:\temp\install\win32\setup.exe). This will use the modified
oraparam.ini and pick up the information from the CD since the absolute
locations are specified.
Choose a Custom install and choose not to create a database during the
install. This way, the Database Configuration Assistant will not be launched
during installation.
The Net8 Configuration Assistant will still be launched, and there is no way
to suppress it. You will need to kill the Net8 Configuration Assistant if it
hangs due to the bug. The installation still will have been successful, and
you can run the DBCA and NetCA after installation.
To kill NetCA if it hangs during installation:
In the "Configuration Tools" window, highlight the "Net8 Configuration
Assistant" and click "Stop". If that does not work, look for the most recent
JRE process using the Task Manager, and kill it manually. NOTE: the OUI
itself will also have a jre process. Be sure to kill the one with the most
recent date, which should be the jre process being used for Net8CA, not the
one for OUI itself.
After killing the configuration tools and continuing through the installation
to the "End of Installation" screen, you should modify the configuration tools
to use "-nojit", then call the appropriate tools from the Start Menu.
Once installation is complete, each of the following files in the ORACLE_HOME
needs to be modified:
assistants\dbca\dbassist.cl
assistants\dbma\dbmig.cl
assistants\ifa\ifa.cl
bin\elogin.cl
bin\owm.cl
ldap\oidamdin\oidadmin.cl
network\tools\netasst.cl
network\tools\netca.cl
owm\install\instelogin.cl
owm\install\instowm.cl
Edit the contents of the above files to add "-nojit" as shown below:
Command=("C:\Program Files\Oracle\jre\1.1.7\BIN\JREW" -nojit -classpath ....
this is the only thing you need to add --> ^^^^^^
Then, launch the necessary tools, like Net8CA and DBCA from the Start Menu.
