添加oracle驱动包：
在lib中添加ojdbc6.jar
在controller中配置插件：
/**
* 配置插件
*/
public void configPlugin(Plugins me) {
/*// 配置C3p0数据库连接池插件
C3p0Plugin c3p0Plugin = new C3p0Plugin(getProperty("jdbcUrl"), getProperty("user"), getProperty("password").trim());
me.add(c3p0Plugin);
// 配置ActiveRecord插件
ActiveRecordPlugin arp = new ActiveRecordPlugin(c3p0Plugin);
me.add(arp);
arp.addMapping("blog", Blog.class); // 映射blog 表到 Blog模型 默认是id
arp.addMapping("em_messages_entities","uuid", EMMessagesEntities.class); // 映射em_messages_entities 表到 EMMessagesEntities模型
arp.addMapping("em_messages_bodies","msg_id", EMMessagesBodies.class); // 映射em_messages_bodies 表到 EMMessagesBodies模型 msg_id为表的主键名
arp.addMapping("em_user","username", EMUser.class); // 映射em_user 表到 UserUploadVideo模型 rowid为表的主键名
arp.addMapping("upload_user_video","videoname", UserUploadVideo.class); // 映射upload_user_video 表到 UserUploadVideo模型 videoname为表的主键名*/
/*Oracle 配置*/
C3p0Plugin cp = new C3p0Plugin(getProperty("jdbcUrl"), getProperty("user"), getProperty("password").trim());
//配置Oracle驱动
cp. setDriverClass("oracle.jdbc.driver.OracleDriver");
me.add(cp);
ActiveRecordPlugin arp = new ActiveRecordPlugin(cp);
me.add(arp);
// 配置Oracle方言
arp.setDialect(new OracleDialect());
// 配置属性名(字段名)大小写不敏感容器工厂
arp.setContainerFactory(new CaseInsensitiveContainerFactory());
// arp.addMapping("user", "user_id", User.class);
// arp.addMapping("EM_MESSAGES_ENTITIES","uuid", EMMessagesEntities.class); // 映射em_messages_entities 表到 EMMessagesEntities模型
// arp.addMapping("EM_MESSAGES_BODIES","msg_id", EMMessagesBodies.class); // 映射em_messages_bodies 表到 EMMessagesBodies模型 msg_id为表的主键名
arp.addMapping("EM_USER","username", EMUser.class); // 映射em_user 表到 UserUploadVideo模型 rowid为表的主键名
// arp.addMapping("UPLOAD_USER_VIDEO","videoname", UserUploadVideo.class); // 映射upload_user_video 表到 UserUploadVideo模型 videoname为表的主键名
}
配置文件：
jdbcUrl =jdbc:oracle:thin:@localhost:1521:jfinalemchat
user = SCOTT
password =123456789
devMode = true

使用Oracle SQLDeveloper连接数据库并创建用户
http://blog.csdn.net/xw13106209/article/details/6594738
操作：
Oracle打开cmd命令窗口 输入 SQLPLUS USERNAME/[email protected]_NAME
SYS密码:
如果忘记了，可以采用如下命令修改SYS密码。
1.首先登陆本地服务器
2.进入命令行
2.sqlplus / as sysdba
4.alter user sys identified by ‘输入密码‘。

权限不足:
以SYS登录，然后执行：GRANT CREATE ANY TABLE TO SCOTT
浏览器打开oracle操作界面：
https://主机名:1158/em
