Question

我在Weblogic Server 12c上创建了一个JNDI。我正在尝试使用数据源连接到服务器上的Oracle数据库，并使用休眠模式在其中创建表。但是我仍然遇到相同的异常 org.hibernate.service.spi.ServiceException：无法创建请求的服务[org.hibernate.engine.jdbc.env.spi.JdbcEnvironment] Part 1 {{ 3}}。我从index.jsp提交ID和名称后出现此异常请查看我的Java代码并提出任何建议：

版本： Java 8 Weblogic 12c 休眠5 甲骨文11g

让我知道您是否需要更多详细信息或问题格式是否需要改进。不是Weblogic btw的专家。谢谢。

Answer 1

对我来说一切都很好。

尝试使用ojdbc6.jar而不是ojdbc14.jar。因为您的Oracle版本是11，而Java是8。ojdbc14.jar现在非常老。

让我知道它是否有效。
