------解决方案--------------------
你的Oracle驱动没装好吧，看看是不是放在classpath下了
------解决方案--------------------
ClassNotFoundException
驱动问题,找不到oracle.jdbc.driver.OracleDriver这个类,去下个驱动,放到classpath中,就是tomcat的common\lib下面
------解决方案--------------------
找不到驱动包
------解决方案--------------------
看看你的Web应用中有没有导入ojdbc.jar包，没有的话当然会报错了
