     //SMS s = new SMS(); 
     SMS.send("9999999999", "password", "8888888888", "Hi How Are u !!"); 

    } 

} 

Aber, wenn ich diesen Code ausführen, ich bin die immer folgende Fehlermeldung:

Exception in thread "main" java.io.IOException: Server returned HTTP response code: 400 for URL: http://www.way2sms.com/FirstServletsms?custid=XXXXXXXXX 
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1615) 
    at SMS.send(SMS.java:115) 
    at SMS.main(SMS.java:142) 

Answer 1

Sie sind nicht der erste, um das Problem zu haben, aber es scheint zu sein, dass die URL, die Sie senden, oder die Daten, die Sie senden möchten, ist falsch.

Einige Vorschläge gefunden here:

• Verwendung Apache Commons HTTP-Client
• Prüfen Sie, ob dies nicht aufgrund eines Proxy auf Ihrer Seite sein könnte (versuchen, von woanders)
• Versuchen Sie stattdessen mit GET von POST
