Java Virtual Machine

The client runs a browser and, in the case of web-deployed forms, the browser runs a Java Virtual Machine (JVM) supplied by JInitiator. JInitiator is the Oracle version of a Sun Microsystems browser plug-in. The plug-in extends the capabilities of the browser so it can present the interface to a form running on an application server. JInitiator takes input from the client as well, but most of the processing, such as validation and trigger code, executes on the application server or database server. It contains the results of network optimizations that Oracle has built into the code. JInitiator contains the same functionality as AppletViewer (an earlier version of the Oracle JVM). Both JInitiator and AppletViewer are pure Java solutions and rely heavily on Sun’s Java implementations. Oracle has certified Microsoft Internet Explorer (IE) Release 5.0 as a stand-alone environment for web-deployed forms with no plug-in (JInitiator) requirement. JInitiator offers some benefits over the native(IE 5.0) browser support, such as on-demand JAR files, which load Java class archive files when required instead of at startup, and persistent JAR file caching, which saves JAR files onto the disk so they can be used from a local installation instead of from a network installation. This saves download time. JInitiator offers the level of support required for running Oracle Applications on the Web.
