your error here:
@managedbean @viewscoped public class login { private facescontext fctx; public login() { fctx = facescontext.getcurrentinstance(); } } you should never assign facescontext instance variable of view/session/application scoped managed bean , reuse in different requests, because current instance of facescontext tied current request makes inherently request scoped (but preferably don't in request scoped beans because of poor style may confusing starters).
the facescontext instance released end of request. in subsequent requests, instance obtained in previous request isn't valid anymore. if have worked, getter methods on externalcontext have returned properties (parameters, cookies, headers, etc) of previous http request , setter methods whould set previous http response committed long. isn't right.
you should obtain on per thread local basis (i.e. straight within method block). in specific case, obtain straight within login() method:
public string login() { facescontext.getcurrentinstance().addmessage(null, new facesmessage(facesmessage.severity_info, "info: ", getusername() + ", " + getpassword() + ", ")); homecoming "start.xhtml"; } jsf jsf-2
