 Connection con;
 PreparedStatement ps;
 String uname,pass;
 ResultSet rs;
%>

{
Class.forName("oracle.jdbc.driver.OracleDriver");
 con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","pro","pro");

推荐答案

你能做的最好的事情是用一个实现JSON RESTFUL Web服务。

The best thing you can do is to implement JSON with a RESTFUL Web Service.

如何创建JSON响应

Android包含JSON类，如JSONArray，JSONObject，可用于解释Web Service将返回的响应。有关详细信息，请参阅此处。

Android includes JSON classes such as JSONArray, JSONObject that can be used to interpret the response the Web Service will return. See more at here.

你不会出错。 JSON很快，如果您实施RESTFUL身份验证，有很多方法可以保护通信。

You can't go wrong. JSON is fast, there are ways to secure the communication if you implement RESTFUL Authentication.

最重要的是，您的Web服务将与iOS应用程序和任何其他具有JSON的平台兼容支持。

Best of all your Web Service will be compatible with iOS Apps and any other platform with JSON support.
