Jinitiator is supplied by Oracle as a way to improve performance between your desktop browser and an Oracle Web server. It does this by controlling the Java operating environment (in programming jargon, the Java Virtual Machine or JVM) and by caching (saving) files on the desktop to reduce network traffic. Jinitiator is implemented as an Active-X component for Microsoft Internet Explorer and as a plug-in for Netscape Navigator. You can tell that you are running Jinitiator if you see an icon of a steaming cup of coffee in the upper left corner of the browser window.
You can find more if you do a google search.
