(一)//装载驱动
      //首先在控制面板中,找到管理工具,然后在里面打开ODBC源,在里面新建一个oracle的数据源,OK即
      //可,这不还很容易。
      Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
      //连接
      Connection ct = DriverManager.getConnection("jdbc:odbc:myorcl","user","psw");//红色的分别为
      //ODBC数据源,oracle里面的账户,相应的密码
      Statement sm = ct.createStatement();
      ResultSet rs = sm.executeQuery("select * from emp");//这句就是例子了

注:此方法只适用于服务器与数据库在同一台电脑上的情况,我在用MyEclipse启动tomcat时可以正常运行,但是部署到tomcat上后,单独启动tomcat,就不能运行了,这个不解,所以我又试了第二种方法。

(二)//装载驱动
      //首先点到你的工程,属性->ADD EXTRA JARS,在到oracle下搜索classes12.jar,并加载进去,具体路
      //径忘了
      Class.forName("oracle.jdbc.driver.OracleDriver");
      //连接
      Connection ct = DriverManager.getConnection("jdbc:oracle:thin:@IP:1521:myorcl");//IP为你本机
      //IP,,因为用localhost和127.0.0.1测试均不好用;myorcl为你的数据库实例
      //下面和第一种方法一样了,就不写了
     //第二种方法还有个有点就是,服务器和数据库可以不在同一台机子上

哎,其实很容易,让我折腾了一天的时间。
