error handling - Why ErrorHandler component is not registering properly in SlingMainServlet? -

i have simple component own errorhandler implementation:

@component(immediate = true) @service @properties(         @property(name = "service.ranking", intvalue = 1) ) public class myerrorhandler implements errorhandler {      @override     public void handleerror(int status, string message, slinghttpservletrequest request, slinghttpservletresponse response) throws ioexception {         handleerror(status, request, response);     }      @override     public void handleerror(throwable throwable, slinghttpservletrequest request, slinghttpservletresponse response) throws ioexception {         handleerror(505, request, response);     }      private void handleerror(int status, slinghttpservletrequest request, slinghttpservletresponse response) throws ioexception {         if (status != 200) {             try {                 request.getrequestdispatcher("/etc/errors/" + status + ".html").forward(request, response);             } catch (servletexception e) {                 throw new illegalstateexception("no error pages");             }     } } 

if deploy component sling, nothings happen until restart of whole sling. it's not solution guess.

short explanation using errorhandler instead of handling scripts (for ask 'why didn't use overloaded script)

1. writing own servlet complex easy behaviour
2. scripts less maintainable java code (in sling).
