Re: Looking for a sample/example desktop

[Les Hazlewood <lh...@apache.org>]

Hi Surendra,

I don't have a working example, but in a standalone desktop
application, there will be almost always a single SecurityManager
instance for the entire client-side JVM.  In this case, it is usually
safe to set the SecurityManager instance as a static singleton:

SecurityUtils.setSecurityManager(myApplicationsShiroSecurityManagerInstance);

from that point on you can call SecurityUtils.getSubject() anywhere in
your UI code and control buttons and such as necessary.

For example:

Button button = new Button("Delete User") {
    @Override
    public boolean isEnabled() {
        Subject currentUser = SecurityUtils.getSubject();
        return currentUser.isPermitted("user:delete") &&
                 super.isEnabled();
    }
}

This may or may not be the best example (it tightly couples your code
to Shiro's API) and you could clean it up using interfaces and
factories and such, but it should give you some ideas.

HTH!

Les
