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:

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.
