i'm trying redirect new page syntax

try {         usuarios usu = new usuarios();         usu.setnombreusuario(request.getparameter("parcodigo"));         system.out.println(usu.getusuario());         usu.setcontrasena(request.getparameter("parcontrasenha"));         system.out.println(usu.getcontrasena());         usu = usuariosdao.login(usu);         system.out.println("es valido? " + usu.isvalid());         if (usu.isvalid()) {             httpsession session = request.getsession(true);             session.setattribute("usuario", usu.getusuario());             response.sendredirect("/kolaescocesacrm/menumobile.jsp");             return;         } else {             response.sendredirect("/kolaescocesacrm/loginmobile.jsp");         }     } catch (exception ex) {         ex.printstacktrace();     }

my problem when submit this:

http://localhost:8084/kolaescocesacrm/srvmenu2?parcodigo=admin&parcontrasenha=kola

i don't know please fine

if dear 404

most of time, because entry application mapped /myapp instead of /(root)

the server says browser go /kolaescocesacrm/loginmobile.jsp should /.myapp/kolaescocesacrm/loginmobile.jsp

the simplest way changing context-path root (/ or empty string)
