Implemented decorator sample (that isn't working yet as well, like my interceptor...).
Finally fixed problem with interceptor and decorator: Renamed bean.xml to beans.xml.
Made interceptors and decorators Serializable.
Apparently, declaration of interceptors and decorators in beans.xml is not needed.
Removed not working logging of intercepted class.
