我编写了一个 java axis2 1.4.1 Web 服务和 .net 3.5 WCF 客户端，我试图捕捉抛出的 wsdl 错误。

与 .net 2.0 不同，.net 3.5 声称支持wsdl:fault并且服务引用向导确实在客户端代理中生成所有正确的故障类。但是当我尝试捕捉错误时，它似乎没有正确序列化，所以我只能catch (FaultException ex)而不是我实际使用的类型FaultException<T>

我查看了我的reference.cs，我可以看到向导已将正确添加FaultContract到我的操作中。

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(Namespace="http://www.mycomp.com/wsdl/Foo", ConfigurationName="FooServiceProxy.Foo")]
public interface Foo {

        [System.ServiceModel.OperationContractAttribute(Action="http://www.mycomp.com/Foo/list", ReplyAction="*")]
 [System.ServiceModel.FaultContractAttribute(typeof(TestWsdlFaultsApp.FooServiceProxy.SimpleFault), Action="http://www.mycomp.com/Foo/list", Name="simpleFault")]
        [System.ServiceModel.XmlSerializerFormatAttribute()]
        TestWsdlFaultsApp.FooServiceProxy.listResponse list(TestWsdlFaultsApp.FooServiceProxy.listRequest request);
    }

我还需要在 .net 中做些什么才能使其正常工作吗？还是 WCF 仅支持来自 .net Web 服务的自定义 wsdl 错误？

这是我的wsdl

WCF should work with axis2 exceptions. I had it working, but I don't remember all the details.

When you use SOAP monitor or something like that, what do you see in the fault message body?

If you're not catching the FaultException<T>, that means you're likely not sending it. Be careful of the XML namespace being used. Take a look at what you're sending, using Fiddler or something like it.

FaultException<T> works fine with Java, or even with WCF.

Thanks john you set me on the right path, Problem was obvious: I was not setting the detail when I threw the fault in java (axis2).

DODGY CODE:

throw new SimpleException("SimpleFault thrown");

WORKING CODE:

 SimpleFault fault = new SimpleFault();
 fault.setReason("SimpleFault reason");

 SimpleFaultE faultMessage = new SimpleFaultE();
 faultMessage.setSimpleFault(fault);

 SimpleException ex = new SimpleException("SimpleFault thrown");
 ex.setFaultMessage(faultMessage);

 throw ex;

So AXIS2 -> WCF wsdl:fault interop works just fine...
