I managed to solve the problem, in case someone has the same problem. Was in the URL

Wrong

conexao = DriverManager.getConnection("jdbc:oracle:thin:@IP:1521/xe", "USUARIO", "SENHA");

Right (MY CONNECTION DIDN’T USE XE BUT THE NAME OF THE SCHEME.

conexao = DriverManager.getConnection("jdbc:oracle:thin:@IP:1521/ESQUEMA, "USUARIO", "SENHA");
