Question

我无法在play框架中连接oracle数据库。我按照以下步骤操作： application.conf文件中的数据库配置如下： default.driver = oracle.jdbc.driver.OracleDriver default.url =＆＃34; JDBC：预言：瘦：@localhost：1521：XE＆＃34; default.username =用户名 default.password =密码 - ＆gt;在项目的lib文件夹中添加了ojdbc14.jar 使用网址http://localhost:9000点击浏览器我收到以下错误：无法连接数据库[默认] 异常如下所示：

     any advice will be appreciated.

基本上，问题是ojdbc14.jar不支持与Play Framework的Oracle连接。

我尝试使用ojdbc6 for Oracle 11g，但它确实有效。

播放框架2.5.10中的Oracle数据库连接
