在TOMCAT 中的SSH 这样配置后日志上显示：



[解决办法]
classpath 里少了hibernate3.jar.
[解决办法]
把hibernate3.jar，数据库驱动包等JAVA类，配置文件中用到的JAR包全放在构建路径里
[解决办法]
我和你的错误差不多拉
也是那个 但是我有hibernate3.jar包
快一天了
还没有解决掉了
[解决办法]
我觉得也像是jar包的问题,
没有加载
org.springframework.orm.hibernate3.LocalSessionFactoryBean]:
Constructor threw exception; nested exception is
类没有定义
java.lang.NoClassDefFoundError: org.hibernate.cfg.Configuration
