jdbc配置文件如下:
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:XE
jdbc.username=system
jdbc.password=lxw1993822
c3p0.pool.maxPoolSize=20
c3p0.pool.minPoolSize=5
c3p0.pool.initialPoolSize=3
c3p0.pool.acquireIncrement=2
我使用sqlplus和pl/sql都可以连接到数据库,但是在javaweb项目中,用jdbc连接却出现这个异常,求大神帮我看看,万分感谢!!!!
