如何修复 "org.apache.cxf.interceptor.Fault: null" [Mule/CXF]
How to fix "org.apache.cxf.interceptor.Fault: null" [Mule/CXF]
我正在使用 cxf 网络服务设置一个 mule 应用程序，遵循 offical document，已经尝试了 jaxws 和简单模式，得到相同的错误。
我正在使用 AnypointStudio 6.6 和 MuleESB 3.9.0 CE。
这是界面和class代码。
package jcoservice;
public interface HelloWorld {
String sayHi(String name);
}
package jcoservice;
public class HelloWorldImpl implements HelloWorld {
public String sayHi(String name) {
return "Hello " + name;
}
}
和骡子流 xml。

您缺少 url 中的 ?wsdl 查询参数。
在浏览器或任何 GET 请求中使用 URL：http://localhost:8881/hello?wsdl
如果没有 ?wsdl，您会收到您描述的错误。
