前台用struts , 数据库用hibernate 出现了这样的错误，请帮忙。。

Question

有可能是你的Tomcat版本问题，建议使用Tomcat6重新试一下

Answer 1

主要是commons-collections.jar包冲突去下载一个最新的，覆盖老的看看另： 看一下你的jar,是不是有2个 主要是commons-collections 的jar啊,只保留最新的。commons-collections-3.2.jar

Answer 2

commons-collections-3.2.jar

Answer 3

谢谢你的建议，我本来的是commons-collections-2.1.jar 然后用你的覆盖了以后，还是有问题，但是报的错误不一样了javax.servlet.ServletException: org/apache/commons/collections/SequencedHashMap

Answer 4

检查一下你的 classpath 的jar 是不是有多个重复的包，重复的老包都删掉。比如 asm-2.2.3.jar 之类的！

Answer 5

阅网上解答，得知为MyEclipse6里面的Hibernate library是有问题的。于是我把Hibernate的库从Build Path中remove掉。然后从网上下载Hibernate，把Hibernate3.jar和其lib下所有jar文件拷贝到我的项目的lib下http://blog.csdn.net/COM_JAVA/archive/2007/12/18/1950413.aspx总之，你目前用的jar估计有问题。

Answer 6

谢谢你 ， 问题已经解决了。 我把commons-beanutils-1.7.0.jar  加到工程里就好使了。
