I'm starting a web page called the "System Properties Repository", aka "What's my line.separator?". This page contains a listing of the values of the Java system properties ("os.name", "line.separator", etc.) for various VMs and platforms. The intention is to allow you to better determine exactly which platform, or which type of platform, your application is running on. I would appreciate submissions for platforms I don't have access to. At the page, I provide an easy to use, pre-compiled class which makes this as easy as possible. The URL is: http://www.tolstoy.com/samizdat/sysprops.html Thanks.
