Installing OneStone® Pebbles
OneStone Pebbles are Java Web Start programs
and will work on most machines running Windows 2000 or above, Apple's OS X, Solaris
and most common Linux configurations. Although Java Web Start programs are launched
by clicking on an html link on a web page, they don't run in the web browser. Instead,
they run in their own window, like a typical desktop program.
This isn't the security risk it might sound like - Web Start programs run in a secure
'sandbox' and don't have access to system resources such as files, user information,
etc, without specific user permission. In the case of OneStone Pebbles, no sensitive
system resources are directly accessed. Access to the graphics hardware takes place
through Sun Microsystems' Java OpenGL package, an official extension of the core
Java run-time. The first time any one of the Pebble modules is loaded, a security
dialog will appear seeking permission to download the JOGL package appropriate for
your computer's operating system. Assuming you give your permission, the JOGL package
will be downloaded and stored on your computer - it's only downloaded once, barring
changes to the JOGL revision level.
Pebbles are designed to download themselves every time they are run.
This ensures you always have the latest version on your systems and is not much
of a burden - Pebbles modules are typically less than 200 KB in size.
There are two principal hardware requirements:
- Monitor/video system must be set to a minimum of 16-bit color depth.
- Video board must support OpenGL 3D graphics.
Assuming your hardware meets these requirements, follow these steps to install and
run a Pebble for the first time:
