带Java客户端null返回的SOAP C#服务器

c# java web-services soap

带Java客户端null返回的SOAP C#服务器,c#,java,web-services,soap,C#,Java,Web Services,Soap,我想检查不同平台之间的SOAP互操作性；我是一名Java程序员，不太懂C语言我在C#中做了些什么：传输对象： using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Xml.Serialization; [XmlRoot] public class Pack { private int id; private string name;

我想检查不同平台之间的SOAP互操作性；我是一名Java程序员，不太懂C语言

我在C#中做了些什么：

        };
    }

调用

getName（）

方法时，它应该返回一个简单字符串，但返回null。当试图通过调用

addPackage（pack）

来添加包时，我从客户机上的C#接收到一个异常，使用Java：

我不认为沟通有任何问题，因为例外情况通过得很好；但我相信我没有向.NET服务器添加任何内容。如果您有任何帮助，我们将不胜感激，并为这篇冗长的文章感到抱歉

NET中的Web服务不在请求之间维护会话状态。当您初始化字典时，它仅在该特定请求期间存在。在随后的请求中，它再次为null，因此您将获得异常
如果您想使用在请求之间持久化的对象实现这样的服务，您可以将应用程序用作共享存储。不过，它看起来有点难看，因为访问它时必须键入cast
初始化：
Application["dictionary"] = new Dictionary<int, Pack>();

Application[“dictionary”]=newdictionary（）；

添加：
((Dictionary<int, Pack>)Application["dictionary"]).Add(package.getId(), package);

（（Dictionary）应用程序[“Dictionary”]）。添加（package.getId（），package）；

阅读：
return ((Dictionary<int, Pack>)Application["dictionary"])[id];

return（（Dictionary）应用程序[“Dictionary”]）[id]；

有关应用程序存储区（HttpApplicationState的一个实例）的更多信息，请访问
，如果没有严格必要，我将永远不会使用soap。我建议您使用RESTWeb服务，将JSON对象放入主体中
 您的.asmx文件（ASP.NET web服务）在哪里
您得到的异常来自PackWS.cs：第38行，它应该是getPackage（）web方法
当我运行PackageClient时，我得到

Hello world!

在.NETWeb服务上，我得到了
System.Collections.Generic.KeyNotFoundException was unhandled by user code
  HResult=-2146232969
  Message=The given key was not present in the dictionary.
  Source=mscorlib

  InnerException: 

要解决这个问题，请遵循Scott上面提到的方法
在签出.NET web服务的整个源代码

和Java客户端
谢谢你的回答；将信息保存到文件似乎是最简单的方法。您还知道为什么在调用[WebMethod][xmlclude（typeof（String））]public String getName（）{返回“再见，世界！”}时会出现null。您是否在更新代码后重新部署了服务以仅返回字符串？我刚刚尝试了您的更新代码，我知道从大多数角度来看REST更好，但这是为了学习目的…只是一个小小的建议，不是为了解决您的问题，只是为了以后的维护，在您的WebService注释中，您使用的是远程wsdl位置，最好使用本地uri（示例：WEB-INF/WebContent/wsdl/Service.wsdl）看起来像是wsdl中的问题。xmlns:soap12=”http://schemas.xmlsoap.org/wsdl/soap12/"
表示您正在使用soap 1.2。您的java客户端是soap 1.1。请尝试使用wsimport
工具生成客户端，它通常会显示错误。您的问题不是您接收的字符串不为null。C#web服务正在抛出错误。您应该在C#端获取堆栈跟踪，以查看null引用的位置发生异常。此外，从浏览器转到此处应该会提供一个表单，您可以在其中直接调用WebMethods。您可以使用该表单查看是否发生异常，以及堆栈跟踪是什么。
