how can I handle error condition during activate()?

[sam lee]

Hey,

I have:

    @Activate
    private void activate(Map<String, ?> config) {
        cdnHost = OsgiUtil.toString(config.get(PROP_CDN_HOST), null);


        if (cdnHost == null) {
            // Do I throw an Exception here?
            // I don't want this component to be Activated if cdnHost isn't
set.
        }

    }


Is exception a proper way?
Or, is there a Service that I can @Reference, that has error flagging
methods?
