Question

前一个星期看夏昕的《SpringGuide》的资料，做了个登录的小练习，运行服务器报错：

望各位前辈指点迷津，以前在网上也找了很多原因，试了都不行。
小弟因为这个原因已经对自学java的信心正慢慢丧失，只是不甘心。

Answer 3

'sessionFactory'的配置有问题。 
org.springframework.orm.hibernate3.LocalSessionFactoryBean这个类是否引入，org.apache.commons.dbcp.BasicDataSource配置是否正确。

Answer 4

你要使用的MyEclipse配置的hibernate和Spring环境
你检查一下Referenced Libaries下面
是否有
asm-2.2.3
asm
这两个jar包，这两个jar包删除一个，重复了注意不要误删了以asm为前缀的包删除之后再重新发布试试

Answer 5

我已经把Spring-Hibernate3.jar包引进来了啊，那org.springframework.orm.hibernate3.LocalSessionFactoryBean这个类也已经引入了，org.apache.commons.dbcp.BasicDataSource配置我检查过 没问题的吧。

Answer 6

导入或替换一个新 的commons-pool.jar

Answer 7

没有这两个包啊，我在导入的Spring 2.0 AOP Libraries这个包里有asm-2.2.3，其他的都没有。
