| # 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.
