Java WSO2碳管理控制台异常

我使用的是WSO2Carbon版本4.0.3，并通过安装WSO2 WSAS应用服务器和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应用程序Aerver（WSO2 AS）中。我使用浏览器测试了部署的服务，效果很好

在进行实验时，我决定使用WSO2 ESB与示例web服务进行交互。我使用WSO2碳管理控制台成功地创建了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，只会显示一个空白页面。查看wso2server控制台日志，每次尝试访问端点时都会引发此异常：

有人能帮我解决这个异常吗

WSO2文档非常模糊，缺乏，我看到示例/信息分散在各个博客中。我发现很难拼凑和收集有关WSO2 ESB设置、理解序列、中介、它们如何相互作用、为什么必须对它们进行配置等方面的信息。

我看到在配置中出现错误时会发生异常。您是否可以尝试转到服务总线->源代码视图，看看您创建的内容是否确实存在？如果您可以看到它，请尝试删除它，这样可能会消除异常。如果无法删除以这种方式创建的端点，请尝试通过转到以下位置来删除它：

$ESB_HOME/repository/deployment/server/synapse-configs/default/endpoints/

如果您发布您正在尝试的端点配置，以重现错误，这可能会有所帮助
