Auto Download of the Java Platform

The Windows releases of Java Plug-in and Java Web Start make use of the codebase attribute of the OBJECT element to autodownload and install a particular version of the JRE. See:

• Auto download with Java Plug-in
• Auto download with Java Web Start

By specifying a particular .cab file in the codebase, a particular version of the JRE can be automatically downloaded and installed as required by an applet or application. For a list of the available .cab files, see Autodownload Files. Note that not every release of the JRE has an associated .cab file for autodownload.

For additional information read the technical article on Auto Install.
