Method Detail

getPermissions

protected PermissionCollection getPermissions(CodeSource codesource)

Returns the permissions for the given codesource object. The implementation of this method first gets the permissions granted by the policy, and then adds additional permissions based on the URL of the codesource.

Then, if the documentURL passed at construction time is not null, the permissions granted to that URL are added. As a result, the jar file code will only be able to connect to the server which served the document.

Parameters: codesource the codesource

Returns: the permissions granted to the codesource
