当我将正确的文件放到“in”文件夹中时，我收到以下错误 -

简称：

但是，如果我删除故障转移配置并且只留下带有“out”目录的简单端点，则该文件将成功处理。
我无法理解为什么故障转移会抛出此类异常以及如何修复它。
答案 0 :(得分：0)
不知何故，通过检查各种选项，我发现如果你更改端点名称，你必须再次对wso2esb服务器调用“publish”命令（在WSO2开发工作室中）。在其他情况下，wso2esb没有看到端点的新名称
我仍然不确定为什么会这样（错误？）。至少，现在我有一个解决方法......
答案 1 :(得分：0)
在我的情况下，我从数据库获取URL，无意中将其设置为空，这就是为什么出现上述问题的原因。
