对于我目前的任务,我必须部署我们在Liferay门户应用。 部署本身是成功的,但是当应用程序在启动时“无合适的驱动程序”会抛出异常。
环境:
- 甲骨文10g快捷
- 休眠4决赛
- Liferay的6使用Tomcat 7
- OJDBC 6
- C3P0 0.9
- 与Maven构建
我们的应用程序的一个旧的.war文件运行没有任何异常。 不过,也有环境的一些小的差异。
旧的环境:
- 甲骨文10g快捷
- Hibernate 3的最终
- Liferay的6使用Tomcat 7
- OJDBC 14
- 在连接池Hibernate的构建
- 建立一个没有行家
事情我已经尝试过:
- 从移动Web应用程序的lib文件夹中ojdbc.jar到Liferay的Tomcat的lib / ext文件夹
- 强制执行的context.xml类加载器的“Web应用类/库/第一资源”的行为:
- 删除C3P0再次使用ojdbc14(我认为这可能ojdbc6引起的)
- SWAP与ojdbc6的ojdbc14在旧版本(它的工作原理)

你有任何想法如何解决这个问题,或者找到所有的根源?
