出错：
2013-4-7 19:44:20 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet ServletTest threw exception
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: com/mchange/v2/c3p0/impl/NewProxyDatabaseMetaData

Answer 1

com/mchange/v2/c3p0/impl/NewProxyDatabaseMetaData

c3p0 的.jar不在lib、CLASSPATH中

追问

在tomcat和项目下我都放了c3p0和mysql的jar包
