Has anyone used xstream with jws?
Each application is, by default, run in a restricted execution environment, similar to the Applet sandbox. The security element can be used to request unrestricted access.
If the all-permissions element is specified, the application will have full access to the client machine and local network. If an application requests full access, then all JAR files must be signed. The user will be prompted to accept the certificate the first time the application is launched.
