Bom dia Galera to começando a mexer com o SuperWaba agora…
E parti para a parte de conexão… Copiei a classe httpConnection que é disponibilizada no próprio site do superwaba só que ela esta dando uns erros e eu não consigo identificar quais são os erros será que alguém poderia me dar uma luz…
Abaixo segue o código da classe httpConnection
package connection;

Bom pelo que vi no eclipse ele da erro nas linhas que contem o seguinte
xkeys.get(x);
Mas será que eu to fazendo algo errado ou tenho que mudar algo mesmo…
Tava olhando na API do Superwaba e a classe vector não contem o método get e nem um outro método que eu possa utilizar para pegar um objeto
