Web服务响应为null，但SOAP消息响应有效

我正在从编写WSDL开始编写web服务。我一直在使用wsimport生成服务器端框架代码，然后编写自己的实现类。我正在Axis2服务器上运行web服务。当使用soapUI时，进出服务的SOAP消息看起来很好，但是当使用web服务客户端时，客户端存根中会出现null。我听说这可能是一个名称空间问题，但我看到了任何错误。这是我的WSDL副本。任何帮助都将不胜感激

这可能是因为单独的WSDL文件

若您在META-INF中单独指定WSDL，那个么AXIS2会将webservice的参数作为OmeElement传递

---

也就是说，如果您在服务API中使用了其他数据类型作为参数，并且在META-INF中使用了WSDL，那么在调用服务时，参数是OmeElement而不是String/int或诸如此类。

我在Soap web服务中遇到了同样的问题，那就是我得到了空响应。我发现原因是我需要在请求中添加适当的头字段：例如-内容类型、内容编码等，具体取决于编写的服务。您最好与编写web服务的人核实一下

您是否也可以发布SOAP请求（从客户端，而不是从SoapUI）？客户机和Web服务在同一个域上吗？
