Question

我们从ojdbc14.jar迁移到ojdbc6.jar以连接到oracle12ee数据库。之后我得到ClasscastException

使用ojdbc7.jar文件检查。改变了eclipselink的版本。已验证的Spring-expression jar文件。已验证的oracle驱动程序声明。

我们正在使用java8，ojdbc6.jar，commons-dbcp-20030825.184428.jar进行oracle12ee连接

最初我认为问题出在TIMESTAMP上，我调试了它。它不会导致问题。当我点击保存时，它会抛出异常。有没有人知道原因是什么。请找到以下例外。

当我做curd操作时，org.apache.commons.dbcp.PoolableConnection无法强制转换为oracle.jdbc.OracleConnection
