I used my service in other places injected automaticaly by angular 2. I want to use the same service in ExceptionHandler. But service doesn't post data to server. I went through debuger and my service invokes.

class MyExceptionHandler extends ExceptionHandler {
  rbJSLogger: RBLoggerService;

  constructor() {
    super(null,null);
    var injector = ReflectiveInjector.resolveAndCreate([
      RBLoggerService,
      JSONP_PROVIDERS,
      Http,
      ConnectionBackend,
      HTTP_PROVIDERS
    ]);
    this.rbJSLogger = injector.get(RBLoggerService);
  }
  call(error, stackTrace = null, reason = null){
    // console.error(stackTrace);
    this.rbJSLogger.searchBy("asd");
  }
}

update ExceptionHandler was renamed to ErrorHandler https://stackoverflow.com/a/35239028/217408

This code

var injector = ReflectiveInjector.resolveAndCreate([...]);

creates a new independent injector that doesn't know anything about services provided in your Angular applications.

You might want to inject the injector used by Angular in your application like

class MyExceptionHandler extends ExceptionHandler {
  rbJSLogger: RBLoggerService;

  constructor(injector:Injector) {
    super(null,null);
    this.rbJSLogger = injector.get(RBLoggerService);
  }
  call(error, stackTrace = null, reason = null){
    // console.error(stackTrace);
    this.rbJSLogger.searchBy("asd");
  }
}

or just

class MyExceptionHandler extends ExceptionHandler {
  rbJSLogger: RBLoggerService;

  constructor(private rbJSLogger:RBLoggerService) {
    super(null,null);
  }
  call(error, stackTrace = null, reason = null){
    // console.error(stackTrace);
    this.rbJSLogger.searchBy("asd");
  }
}
