A customer of mine who deploys Oracle Forms 10g on the wild wild web, ran into a little problem.
They don't have control over the java plugin being installed on the client machine and with the latest java 1.7 update
they encountered the following forms error :
FRM-92095: Oracle Jnitiator version too low - please install version 18.104.22.168 or higher
Doh - we're running java 1.7 - not Oracle's obscure Jnitiator.
This seems to be a know issue on metalink see
