--------------------编程问答-------------------- struts.xml 确实是放在 src 目录中了么？也就是确认其会被发布到：WEB-INF\classes目录中？ --------------------编程问答-------------------- 不错哦 --------------------编程问答-------------------- 我认为是很狗血的错误。 --------------------编程问答-------------------- 我确认放置到SRC目录，但还是以上错误
--------------------编程问答--------------------
表单里面加上一个namespace="/"试试看 --------------------编程问答-------------------- 你的struts配置文件，名字错了，你写成strutsl.xml了。 --------------------编程问答--------------------
哥们慧眼呀,在配置时最怕的就是粗心大意了，写错一个单词找半天的错误（在能找到的前提下），LZ要细心哦 --------------------编程问答-------------------- 这种问题确实够让人哭笑不得。不过也确实犯过类似的问题。 --------------------编程问答--------------------
多了个 L， 害死人啊。。。还好楼主贴了图。
补充：Java , Web 开发
