我的web.xml配置如下

用得action-servlet.xml如下:

</bean>
</beans>

哪位朋友帮帮忙!小妹这厢有礼了!!

[miaoliujun]

从你的异常来看，可能是commons-collection的版本不对

[miaoliujun]

或者你引用了多个commons-collection-XXX.jar

[老紫竹]

org.apache.commons.collections.ArrayStack

1 删掉你的 WEB-INF/lib 目录下面的 commons-collection的jar
2 清理你的 tomcat/shared/lib 目录下面的jar, 只保留最新的，删掉老的

[gongyali2005]

ssh真是相当的麻烦,同情中.......

[zhlsyc]

服务器启动出错了，你的类包commons-collection可能有几个版本

[Danny.SHI]

找本《struts开发入门与项目实践》看看，网上可以下到这本书的源码
里面有关于留言板的例子。。。
祝好运！

[laitaogood]

一个留言板，用SSH，至于吗，呵呵

[lyboyc]

我现在用maven2自己搭环境，所有依赖自己加。

这么漂亮还做程序，难能可贵，呵呵，

[chg2008]

一般情况是lib目录下多了commons-collection的jar包
建议只保留一个

[FreedomLeo]

这个问题已经解决了，果然是 commons-collection的问题
呵呵,谢谢各位了!!!

[FreedomLeo]

搞ssh真的是比较痛苦,以后小妹要多仰仗各位前辈指导帮忙了!!!

[jiangyong123]

我的lib下面没有多个commons-collection的jar包啊，怎么也出现这个问题？

[yangguoyk]

同样的问题,为什么不同的解法?
