Problem with orion.jar in oc4j

Ranga S

Additional info.
I have downloaded oc4j from following link
http://otn.oracle.com/software/products/ias/devuse.html which runs on all platforms. It is a zip file of about 19MB.
According to installation instructions I have unzipped it and given command % java -jar orion. jar -install ,but there is no file named orion.jar.
How can I get orion.jar or entire oc4j which can be insalled on win98?
It depends on the version.
This could work>

java -jar oc4j.jar -install
