java - 如何用blazeds+java+flex+tomcat实现一个web app？

Question

我正在用 flex blazeds 和 Java 编写一个网络应用程序。我安装了使用 WTP 混合项目的 Eclipse 插件。当我运行我的 flex 服务时，我正在使用 flex 的服务器，该服务器使用 tomcat 的模拟，web 应用程序获得了数据，一切正常。问题是当我用我的 tomcat 或 blazeds 的 tomcat 中的 flex 生成的所有文件复制项目时，它不起作用，这是因为我想在服务器上实现我的应用程序错误是:

我不知道为什么 tomcat 找不到用于 my-amf 'http://172.16.8.245:8400/IEC-BLAZEDS/messagebroker/amf 的 flex.messaging.endpoints.AMFEndpoint 类'.一切都在 flex 拥有的模拟服务器中运行良好。

确保 web.xml 有一个用于消息代理的 servlet，并且 BlazeDS 库位于您的 WEB-INF/lib 文件夹中。
