java - EditText.setText error -

-

resolved! problem used this.findviewbyid, use dialog.findviewbyid. tnx , beg pardon!

i've strange (for me) problem. try write in edittext string readed cursor, , know that's correct way:

edittext mytext;       final dialog dialog = new dialog(this);      dialog.setcontentview(r.layout.login);      dialog.settitle("login");      dialog.setcancelable(true);       cursor lista=db.listaparametri();       try         {             while (lista.movetonext())             {                  if (lista.getstring(0).equals("username"))                 {                      mytext =  (edittext) this.findviewbyid(r.id.username);                      log.d("log", lista.getstring(1));                      mytext.settext( lista.getstring(1) );                     }                }         }                 {             lista.close();         }

but when try write whit settext() return error:

what's up? tnx!

either:

  1. your textedit has not been defined (but if can other things itthen should fine)
  2. lista.getstring(1) null, try printing catlog saying log.d("log", lista.getstring(1)); should output value of string.

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
