我正在使用 WSO2Carbon 4.0.3 版，并通过安装 WSO2 WSAS 应用程序服务器和 WSO2 ESB 对其进行了配置。
我创建了一个 RESTful (JAX-RS) 示例 Web 服务并将其部署到 WSO2 Application Aerver (WSO2 AS)。我使用浏览器测试了部署的服务，它工作正常。
在进行试验时，我决定使用 WSO2 ESB 与示例 Web 服务进行交互。我使用 WSO2 Carbon 管理控制台成功创建了 Web 服务的端点。
现在，当我尝试查看使用管理控制台上的菜单创建的端点时，只显示一个空白页面。查看 wso2server 控制台日志，我看到每次尝试访问端点时都会抛出此异常：

谁能帮我解决这个异常？
WSO2 文档非常模糊，缺乏，我看到分散在各个博客中的示例/信息。我发现很难拼凑和收集有关 WSO2 ESB 设置、理解序列、中介、它们如何相互交互、为什么必须配置它们等的信息。
