Erro ao compilar o codigo.

Boa tarde, galera.

eu estou testando meu arduino duemilanove atmega 328 + ethernet shield wiznet 5100.

Tentei compilar o seguinte código:

#include <WString.h>
#include <Ethernet.h>
/*
   Simple Ethernet Test

        Arduino server outputs simple text to browser

   The circuit:
   * Arduino Duemilanove
        * Arduino Ethernet shield
        * Basic FTDI breakout 5V
        *LED connected to GND and digital pin 4 via resistor
   
        By Minde

byte gateway[] = { 192, 168, 1, 1 };         // internet access via router

          //stopping client
          client.stop();
            }
          }
        }
      }
}     





Só que ele me apresenta o seguinte erro:

ethtest.cpp: In function 'void loop()':
ethtest:46: error: 'class String' has no member named 'append'
ethtest:53: error: 'class String' has no member named 'contains'


Alguém pode me ajudar?

Consegui fazer funcionar...

O Rafael me ajudou...

Agora é implementar! :D
