我已经下载了 blazeds3.3 并将所有 lib 文件复制到我的 lib 文件夹中并添加了上面的 web.xml 文件。

然后我创建了具有 BlazeDS 支持的 Flex 4 项目。它已创建，没有任何错误。然后我在代码中添加了数据网格。在使用 Flex 4 以数据为中心的驱动功能时，它会询问我用户名和密码。我已选中“无需密码” 然后它给我错误，比如

Error Executing RDS command. Status code 404, Reason: Servlet RDSDispatchServlet is not available

请帮助我。

Answer 1

BlazeDS 3.3 中似乎没有 RDS 内容。据我所知，它是 v4 及以上版本。

因此，由于在类路径上找不到该类，您的服务器可能无法启动 servlet。
