一直在纠结这个问题，但长久找不出原因
下面列子我从官网下了参考的，但还是报同样的错！
请高手们帮我看看到底是什么原因啊？我把我的列子上传上来了！
多谢！

我最近也搭建了这么一个框架 spring集成flex，也遇到过这个问题，我已经把我搭建的框架放到了博客里了，你可以去看看。我也是刚开始学flex。互相学习。

从这里入手检查吧。

Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name '_messageBroker' defined in ServletContext resource [/WEB-INF/config/web-application-config.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/apache/xpath/CachedXPathAPI

虽然不知道你哪里找的例子，但是显然有些地方没有copy完

大致上你的web.xml少了flex的servlet配置

感觉像是缺少jar包

ps: spring 和 flex 貌似不存在什么集成吧，二者分的很开。

从这句话来判断，应该是用错jar包或jar包冲突造成的~

SPRING和FLEX怎么集成....FLEX现在有后端了吗?

应该是 Spring 整合 BlazedDS ,Spring 提供了有官方的整合方案不像早之前那样要自己加工“兵工厂”，去spring 官网上 找 找 ，有很完整的例子的，1.5以上好像支持blazeds4.0以上版本。

已经放弃flex了,前台用这个很蛋疼!!
