Java Web 服务使用 .Net

Question

我已经通过右键单击并添加服务引用将 java web 服务用于我的 asp.net 项目。

public static salim.HakedisServiceClient ws = new salim.HakedisServiceClient("HakedisServiceImplPort"); ws.ClientCredentials.UserName.UserName = "****"; ws.ClientCredentials.UserName.Password = "****"; var lstCities = ws.getCities();

但它有一个例外：

System.ServiceModel.FaultException :{"处理时发生故障。"} 服务器堆栈跟踪： 在 System.ServiceModel.Channels.ServiceChannel.HandleReply（ProxyOperationRuntime 操作，ProxyRpc& rpc） 在 System.ServiceModel.Channels.ServiceChannel.Call（字符串操作，布尔单向，ProxyOperationRuntime 操作，Object[] 输入，Object[] 输出，TimeSpan 超时） 在 System.ServiceModel.Channels.ServiceChannel.Call（字符串操作，布尔单向，ProxyOperationRuntime 操作，Object[] 输入，Object[] 输出） 在 System.ServiceModel.Channels.ServiceChannelProxy.InvokeService（IMethodCallMessage 方法调用，ProxyOperationRuntime 操作） 在 System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage 消息)

在 [0] 处重新抛出异常： 在 System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage（IMessage reqMsg，IMessage retMsg） 在 System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke（MessageData& msgData，Int32 类型） 在 salim.HakedisService.getCities（getCities 请求） 在 c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\website1\bdbbd757\4abd3cb7\App_WebReferences.mggi9qhe.0.cs 中的 salim.HakedisServiceClient.salim.HakedisService.getCities（getCities 请求）：第 1392 行 在 c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\website1\bdbbd757\4abd3cb7\App_WebReferences.mggi9qhe.0.cs:line 1398 中的 salim.HakedisServiceClient.getCities() 在 c:\Users\htsapp\Documents\Visual Studio 2008\WebSites\WebSite1\Default.aspx.cs:line 80 中的 _Default.Page_Load(Object sender, EventArgs e) 在 System.Web.Util.CalliHelper.EventArgFunctionCaller（IntPtr fp，对象 o，对象 t，EventArgs e） 在 System.Web.Util.CalliEventHandlerDelegateProxy.Callback（对象发送者，EventArgs e） 在 System.Web.UI.Control.OnLoad(EventArgs e) 在 System.Web.UI.Control.LoadRecursive() 在 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

还有这样的网络服务：

<wsdl:types></wsdl:types>
<wsdl:message name="getFloors"></wsdl:message>

<wsdl:binding name="HakedisSoapBinding" type="tns:HakedisService"></wsdl:binding>      <wsdl:service name="Hakedis"></wsdl:service></wsdl:definitions>

有人推荐吗？

尝试如下设置您的连接：

 HakedisServiceClient client = null;
            ChannelEndpointElement endpoint = null;

            ClientSection clientSection = ConfigurationManager.GetSection("system.serviceModel/client") as ClientSection;              
            ChannelEndpointElementCollection endpointCollection = clientSection.ElementInformation.Properties[string.Empty].Value as ChannelEndpointElementCollection;
            foreach (ChannelEndpointElement endpointElement in endpointCollection)
            {
                if (endpointElement.Name == "BasicHttpBinding_HakedisService") //BasicHttpBinding_HakedisService from your  config file client endpoint  entries
                {
                    endpoint = endpointElement;
                }
            }

            if (endpoint != null)
            {

                BasicHttpBinding binding = new BasicHttpBinding(endpoint.Name);

                binding.SendTimeout = TimeSpan.FromMinutes(1); //Set all this as appropriate
                binding.OpenTimeout = TimeSpan.FromMinutes(1);
                binding.CloseTimeout = TimeSpan.FromMinutes(1);
                binding.ReceiveTimeout = TimeSpan.FromMinutes(10);
                binding.AllowCookies = false;
                binding.BypassProxyOnLocal = false;
                binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
                binding.MessageEncoding = WSMessageEncoding.Text;
                binding.TextEncoding = System.Text.Encoding.UTF8;
                binding.TransferMode = TransferMode.Buffered;
                binding.UseDefaultWebProxy = true;
                binding.MaxBufferSize = 100000; //as large as needed
                binding.MaxReceivedMessageSize = 100000; //as large as needed
                binding.TextEncoding = Encoding.UTF8;


                System.ServiceModel.EndpointAddress address = new System.ServiceModel.EndpointAddress(endpoint.Address.AbsoluteUri);
                SSLAccessPolicy.AllowSSLConnection();
                client = new HakedisServiceClient(binding, address);

                SSLAccessPolicy.AllowSSLConnection(); // only if ssl enabled
                client.Open(); // Now open the client socket.

希望对您有所帮助（您可以先调试通过）。
