Need input on RxJS :Angular2

[SankarReddy]

Hi,
Basically I am trying to handle the error messages globally for all http calls.Find the below snippet.

private handleError(error: Response) {
Rx.Observable.throw(new Error("error is generated"));
}

return this.sendRequest(new Request(options), headerArgs).map(res => res.json()).catch(this.handleError);


this.loginService.onLoginService(this.user).subscribe(
result => { console.log("executed succesfully";},
error => { console.error("failed to execute"+error);}

);

I should get the output as "failed to execute error is generated".But I am getting Observable is not defined in onLoginServiceMethod at error function.Pls let me know if anyone knows this

Are you getting any 404's in network panel? Observable is undefined sounds like the library is not loaded.
