Why Security in Web Start

[Saravanan Subramanyan]

Hi,
I have one doubt in Jav WebStart. Java WebStart has the security similar to Applet. it means, it won't allow us to access the local resources. I agree this point. But why it don't allow us to read and write the system properties and create classloader. Since each application in webstart is started in different JVM, modifying system properties will not affect the other application. Can anyone clarify me in this regard.
Thanks and Regards

I would expect it is because you don't want just anything downloaded onto your computer. Wouldn't that make viruses easier to spread?
