我从别人那里拿了项目得源码和数据库的.dmp文件，然后我把.dmp文件导入到oracle中，项目使用SSH框架做的，然后我改了spring的配置文件。但是启动tomcat6.0的时候报错了警告: oracle.jdbc.driver.OracleConnection@63b2e6 threw an Error when we tried to check its default holdability. This is probably due to a bug in your JDBC driver that c3p0 can harmlessly work around (reported for some DB2 drivers). Please verify that the error stack trace is consistentwith the getHoldability() method not being properly implemented, and is not due to some deeper problem. This message will not be repeated for Connections of type oracle.jdbc.driver.OracleConnection that provoke errors of type java.lang.AbstractMethodError when getHoldability() is called.严重: Context initialization failed
