Sto tentando di utilizzare il servizio web per recuperare i dati dal server. Seguo il tutorial specificato in http://googcloudlabs.appspot.com/codelabexercise5.html, ovviamente ho modificato il codice originale per soddisfare le mie richieste.Tipo di contenuto non supportato: text/html; charset = UTF-8 I supportati sono: [text/xml]
Ora ricevo un errore simile al seguente: Tipo di contenuto non supportato: text/html; charset = UTF-8 quelli supportati sono: [text/xml]
Per visualizzare l'errore completo, scrivo una nuova funzione di errore quando ottiene i dati:
var errorFn = function(e){
for(var p in e){
alert(e[p]);
}
}
var successFn = function(resp){
var data='';
if(resp){
//getting the data from the response object
data=resp.data;
}
//Some other code here...
}
getData("/entity",null,successFn,errorFn);
E il browser avvisa l'oggetto di errore:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<title>Error 500 Unsupported Content-Type: text/html; charset=UTF-8 Supported ones are: [text/xml]</title>

Qualcuno mi aiuti con questo problema ??
Grazie in anticipo!
Sì, penso di sì @Peter ma dove posso configurare le richieste HTTP, nella classe servlet o da qualche parte nella directory/war ?? – sinhzun
@Peter Dove è necessario specificare l'intestazione Content-Type? La richiesta HTTP non è con me. Chiamiamo solo un metodo esposto da wsdl. Sono sicuro che mi manca qualcosa. Per favore guida. – instanceOfObject
