Question

我正在使用wso2 esb 4.0.3并创建了一个wso2数据服务，它通过传递两个输入参数并获得16列作为响应来调用teradata过程。

有时它会给出正确的输出，但有时它会给出错误：

我怎样才能得到持续的回应？

Answer 1

 HTTPSender Unable to sendViaPost to url[http://localhost:8280/services/SampleSemsDataService1.SOAP12Endpoint]

您的数据服务是在端口8280上运行的吗？您是否在ESB中安装了DS功能？如果是这样，你应该使用servlet传输（端口9763/9443）而不是NIO传输

对于wso2数据服务，获取inputstream不能为null
