Product Registration is FREE and includes many benefits:

* Notification of new versions, patches, and updates

* Special offers on Sun products, services and training

* Access to early releases and documentation

Product and system data will be collected. If your configuration

supports a browser, the Sun Product Registration form for

the JDK will be presented. If you do not register, none of

this information will be saved. You may also register your

JDK later by opening the register.html file (located in

the JDK installation directory) in a browser.

For more information on what data Registration collects and

how it is managed and used, see:
