• Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

  - by Paul J. Warner

  I am having an issue with a program where after 6 mins +- 5 secs we get the above exception. Some more info about the exception stacktrace is below. This all happens pretty religiously, 6 mins goes by and bam the following 3 exeptions. We have the application installed in 2 other environments and it is working fine there. I am hoping to find some server settings either IIS 6 or Server 2003 settings that may be causing this issue to occur. I have reviewed some of the similar questions and don't see very many answers. I am hoping that maybe the information I have provided may help a little bit. 208741,Exception,,,,2011-06-21 00:30:14.193,SERVERNAME,2624,1,CLIENTNAME,The underlying connection was closed: An unexpected error occurred on a receive. , at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at Microsoft.Web.Services3.WebServicesClientProtocol.GetResponse(WebRequest request, IAsyncResult result) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.FixedSizeReader.ReadPacket(Byte[] buffer, Int32 offset, Int32 count) at System.Net.Security._SslStream.StartFrameHeader(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartReading(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessRead(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.TlsStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead),2004437127,114,1 208742,Exception,,,,2011-06-21 00:30:14.227,SERVERNAME,2624,1,CLIENTNAME,Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. , at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.FixedSizeReader.ReadPacket(Byte[] buffer, Int32 offset, Int32 count) at System.Net.Security._SslStream.StartFrameHeader(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartReading(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessRead(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.TlsStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead),2004437127,114,1 208743,Exception,,,,2011-06-21 00:30:14.287,SERVERNAME,2624,1,CLIENTNAME,An existing connection was forcibly closed by the remote host , at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size),-691097507,62,1

• upload process times out for different time zones

  - by shilezi

  I have an inhouse(NY) app that cients can upload files to. Usually uploads go pretty quickly for most clients but this particularly cient in the UK always have problems with uploads. not sure if they get any errors but since we log all exceptions, we see this...Error: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Net.WebException: The operation has timed out at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at ... This shouldn't even be an issue because since we noticed they have had this issue before so we bumped up these to maxRequestLength="2097151" executionTimeout="14400". Further investigating this error, i read that it could be a thread timeout since the default is 20minute. A worker process with process id of serving application pool was shutdown due to inactivity. Application Pool timeout configuration was set to 20 minutes. A new worker process will be started when needed. Problem is I am not entirely sure if that really is the case as all other cients mostly North American, have no issues but then their uploads don't seem to go beyond 80mb and the UK client have done a 700mb upload before that i know of. We have tested 750mb before and the whole process took about 15min for upload and processing. Any help on what the real issue here might be? Thanks.

• How can I disable keep-alive on ASP.NET Web Service client requests?

  - by Matthew Brindley

  I have a few web servers behind an Amazon EC2 load balancer. I'm using TCP balancing on port 80 (rather than HTTP balancing). I have a client polling a Web Service (running on all web servers) for new items every few seconds. However, the client seems to stay connected to one server and polls that same server each time. I've tried using ServicePointManager to disable KeepAlive, but that didn't change anything. The outgoing connection still had its "connection: keep-alive" HTTP header, and the server kept the TCP connection open. I've also tried adding an override of GetWebRequest to the proxy class created by VS, which inherits from SoapHttpClientProtocol, but I still see the keep-alive header. If I kill the client's process and restart, it'll connect to a new server via the load balancer, but it'll continue polling that new server forever. Is there a way to force it to connect to a random server each time? I want the load from the one client to be spread across all of the web servers. The client is written in C# (as is the server) and uses a Web Reference (not a Service Reference), which points to the load balancer.

• C# webservice async callback not getting called on HTTP 407 error.

  - by Ben

  Hi, I am trying to test the use-case of a customer having a proxy with login credentials, trying to use our webservice from our client. If the request is synchronous, my job is easy. Catch the WebException, check for the 407 code, and prompt the user for the login credentials. However, for async requests, I seem to be running into a problem: the callback is never getting called! I ran a wireshark trace and did indeed see that the HTTP 407 error was being passed back, so I am bewildered as to what to do. Here is the code that sets up the callback and starts the request: TravelService.TravelServiceImplService svc = new TravelService.TravelServiceImplService(); svc.Url = svcUrl; svc.CreateEventCompleted += CbkCreateEventCompleted; svc.CreateEventAsync(crReq, req); And the code that was generated when I consumed the WSDL: public void CreateEventAsync(TravelServiceCreateEventRequest CreateEventRequest, object userState) { if ((this.CreateEventOperationCompleted == null)) { this.CreateEventOperationCompleted = new System.Threading.SendOrPostCallback(this.OnCreateEventOperationCompleted); } this.InvokeAsync("CreateEvent", new object[] { CreateEventRequest}, this.CreateEventOperationCompleted, userState); } private void OnCreateEventOperationCompleted(object arg) { if ((this.CreateEventCompleted != null)) { System.Web.Services.Protocols.InvokeCompletedEventArgs invokeArgs = ((System.Web.Services.Protocols.InvokeCompletedEventArgs)(arg)); this.CreateEventCompleted(this, new CreateEventCompletedEventArgs(invokeArgs.Results, invokeArgs.Error, invokeArgs.Cancelled, invokeArgs.UserState)); } } Debugging the WS code, I found that even the SoapHttpClientProtocol.InvokeAsync method was not calling its callback as well. Am I missing some sort of configuration?

• Replace low level web-service reference call transport with custom one

  - by hoodoos

  I'm not sure if title sounds right actually, so I will give more explanation here. I will begin from very beginning :) I'm using c# and .net for my development. I have an application that makes requests to some soap web-service and for each user request it produces 3 to 10 requests for web-service, they should all run async to finish in one time, so I use Async method of the web-service generated reference and then wait for result on callback. But it seems like it starts a thread (or takes it from pool) for every async call I make, so if I have 10 clients I got to spawn 30 to 100 threads and it sounds terrible even for my 16 cores server :) So i wanted to replace low level transport implementation with my own which uses non-blocking sockets and can handle at least 50 sockets run parallel in one thread with not much overhead. But I actually dunno where to put my override best. I analyzed System.Web.Services.Protocols.SoapHttpClientProtocol class and see that it has some GetWebRequest method which I actually could use. If only I could somehow interupt the object it creates and get a http request with all headers and body from there and then send it with my own sockets.. Any ideas what approach to use? Or maybe there's something built in the framework I can use?

• web service client authentication

  - by Jack

  I want to consume Java based web service with c#.net client. The problem is, I couldnt authenticate to the service. it didnt work with this: mywebservice.Credentials = new System.Net.NetworkCredential(userid, userpass); I tried to write base class for my client method. public class ClientProtocols : SoapHttpClientProtocol { protected override WebRequest GetWebRequest(Uri uri) { System.Net.WebRequest request = base.GetWebRequest(uri); if (null != Credentials) request.Headers.Add("Authorization", GetAuthHeader()); return request; } protected override WebResponse GetWebResponse(WebRequest request) { WebResponse response = base.GetWebResponse(request); return response; } private string GetAuthHeader() { StringBuilder sb = new StringBuilder(); sb.Append("Basic "); NetworkCredential cred = Credentials.GetCredential(new Uri(Url), "Basic"); string s = string.Format("{0}:{1}", cred.UserName, cred.Password); sb.Append(Convert.ToBase64String(Encoding.ASCII.GetBytes(s))); return sb.ToString(); } } How can I use this class and authorize to the web service? Thanks.

• web service slowdown

  - by user238591

  Hi, I have a web service slowdown. My (web) service is in gsoap & managed C++. It's not IIS/apache hosted, but speaks xml. My client is in .NET The service computation time is light (<0.1s to prepare reply). I expect the service to be smooth, fast and have good availability. I have about 100 clients, response time is 1s mandatory. Clients have about 1 request per minute. Clients are checking web service presence by tcp open port test. So, to avoid possible congestion, I turned gSoap KeepAlive to false. Until there everything runs fine : I bearly see connections in TCPView (sysinternals) New special synchronisation program now calls the service in a loop. It's higher load but everything is processed in less 30 seconds. With sysinternals TCPView, I see that about 1 thousands connections are in TIME_WAIT. They slowdown the service and It takes seconds for the service to reply, now. Could it be that I need to reset the SoapHttpClientProtocol connection ? Someone has TIME_WAIT ghosts with a web service call in a loop ?

• System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

  - by coffeeaddict

  We have 2 identical database tables on our dev server. In both is a table that holds an X509Certificate2 data in one of its fields. When I grab the cert along with the password that I've been using all along, it works over the first database just fine. I run the same code though over the 2nd database and get this error and I don't get why if the setup is exactly the same and the database is also on this server. So I'm not sure why when I switch my connection string to talk to Database2, even though it's setup the same and the code I'm running over it is the same, it complains. Here's the stack trace: An existing connection was forcibly closed by the remote host Description: An unhandled exception occurred during the execution of the current web request.

• An existing connection was forcibly closed by the remote host

  - by George

  I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while, I get the subject error. The error happenes The error seems to occur in < 1 min, which is far less that the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server. It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Smit.Pipeline.Bo.localhost.WsSR.SaveOptions(String emailId, DataSet dsNeighborhood, DataSet dsOption, DataSet dsTaskApplications, DataSet dsCcUsers, DataSet dsDistinctUsers, DataSet dsReferencedApplications) in C:\My\Code\Pipeline2\Smit.Pipeline.Bo\Web References\localhost\Reference.vb:line 944 at Smit.Pipeline.Bo.Options.Save(TaskApplications updatedTaskApplications) in I've been looking a tons of postings on this error and it is surprising at how varied the circumstances which cause this error are. I've tried messing with Wireshark, but I am clueless how to use it. This application only has about 20 users at any one time and I am able to reproduce this error in the middle of the night when probably no one is using the app, so I don't think that the number of requests to the web server or to the database is high. It's probably one right now when I just got the error now. It seems to have to do everything with the amt of data being passed in either direction. This error is really chronic and killing me. Please help.

  I just installed Dynamics CRM 4.0. It is working nicely except for workflows. They won't start. I turned on tracing and it appears that there is an IO error. The server is setup with IFD and SSL.

It was blank. That didn't appear to work. After some more research, I think this might be caused because the Asynch service can't access the SDK web services using SSL. If this is correct, how would one configure a CRM server for secure access, internal and external (IFD) and still allow asynch service to hit web site? Thanks for your help!

• A SelfHosted WCF Service over Basic HTTP Binding doesn't support more than 1000 concurrent requests

  - by Krishnan

  I have self hosted a WCF Service over BasicHttpBinding consumed by an ASMX Client. I'm simulating a concurrent user load of 1200 users. The service method takes a string parameter and returns a string. The data exchanged is less than 10KB. The processing time for a request is fixed at 2 seconds by having a Thread.Sleep(2000) statement. Nothing additional. I have removed all the DB Hits / business logic. The same piece of code runs fine for 1000 concurrent users. I get the following error when I bump up the number to 1200 users. System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at WCF.Throttling.Client.Service.Function2(String param) This exception is often reported on DataContract mismatch and large data exchange. But never when doing a load test. I have browsed enough and have tried most of the options which include, Enabled Trace & Message log on server side. But no errors logged. To overcome Port Exhaustion MaxUserPort is set to 65535, and TcpTimedWaitDelay 30 secs. MaxConcurrent Calls is set to 600, and MaxConcurrentInstances is set to 1200. The Open, Close, Send and Receive Timeouts are set to 10 Minutes. The HTTPWebRequest KeepAlive set to false. I have not been able to nail down the issue for the past two days. Any help would be appreciated. Thank you.

• Object of type 'customObject' cannot be converted to type 'customObject'.

  - by Phani Kumar PV

  i am receiving the follwing error when i am invoking a custom object "Object of type 'customObject' cannot be converted to type 'customObject'." Following is the scenario when i am getting the error i am invoking a method in a dll dynamically. Load an assembly CreateInstance.... calling MethodInfo.Invoke() passing int, string as a parameter for my method is working fine = No exceptions are thrown. But if I try and pass a one of my own custom class objects as a parameter, then I get an ArgumentException exception, and it is not either an ArgumentOutOfRangeException or ArgumentNullException. "Object of type 'customObject' cannot be converted to type 'customObject'." I am doing this in a web application. The class file containing the method is in a different proj . also the custom object is a sepearte class in the same file. there is no such thing called a static aseembly in my code. I am trying to invoke a webmethod dynamically. this webmethod is having the customObject type as an input parameter. So when i invoke the webmethod i am dynamically creating the proxy assembly and all. From the same assembly i am trying to create an instance of the cusotm object assinging the values to its properties and then passing this object as a parameter and invoking the method. everything is dynamic and nothing is created static.. :( add reference is not used. Following is a sample code i tried to create it public static object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args) { System.Net.WebClient client = new System.Net.WebClient(); //-Connect To the web service using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl")) { //--Now read the WSDL file describing a service.

See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ********** Exception Text ********** System.InvalidOperationException: Unable to generate a temporary class (result=1). error CS2001: Source file 'C:\WINDOWS\TEMP\wz58eig4.0.cs' could not be found error CS2008: No inputs specified at System.Xml.Serialization.Compiler.Compile(Assembly parent, String ns, XmlSerializerCompilerParameters xmlParameters, Evidence evidence) at System.Xml.Serialization.TempAssembly.GenerateAssembly(XmlMapping[] xmlMappings, Type[] types, String defaultNamespace, Evidence evidence, XmlSerializerCompilerParameters parameters, Assembly assembly, Hashtable assemblies) at System.Xml.Serialization.TempAssembly..ctor(XmlMapping[] xmlMappings, Type[] types, String defaultNamespace, String location, Evidence evidence) at System.Xml.Serialization.XmlSerializer.GetSerializersFromCache(XmlMapping[] mappings, Type type) at System.Xml.Serialization.XmlSerializer.FromMappings(XmlMapping[] mappings, Type type) at System.Web.Services.Protocols.SoapClientType..ctor(Type type) at System.Web.Services.Protocols.SoapHttpClientProtocol..ctor() at SSOClient..ctor() at sc.tradesvc.SSOManager..ctor() at sc.tradesvc.SSOManager.get_Inst() at sc.cashflowgenerator.Controls.LoginForm.btnLogin_Click(Object sender, EventArgs e) at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.PerformClick() at System.Windows.Forms.Form.ProcessDialogKey(Keys keyData) at System.Windows.Forms.TextBoxBase.ProcessDialogKey(Keys keyData) at System.Windows.Forms.Control.PreProcessMessage(Message& msg) at System.Windows.Forms.Control.PreProcessControlMessageInternal(Control target, Message& msg) at System.Windows.Forms.Application.ThreadContext.PreTranslateMessage(MSG& msg) ********** Loaded Assemblies ********** mscorlib Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.1433 (REDBITS.050727-1400) CodeBase: file:///C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/mscorlib.dll CashflowGenerator Assembly Version: 1.0.0.0 Win32 Version: 1.0.0.0 CodeBase: file:///C:/DATA/DEVEL/Output/CashflowGenerator.exe System.Windows.Forms Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.1433 (REDBITS.050727-1400) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll System Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.1433 (REDBITS.050727-1400) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System/2.0.0.0__b77a5c561934e089/System.dll System.Drawing Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.1433 (REDBITS.050727-1400) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Drawing/2.0.0.0__b03f5f7f11d50a3a/System.Drawing.dll System.Configuration Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.1433 (REDBITS.050727-1400) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Configuration/2.0.0.0__b03f5f7f11d50a3a/System.Configuration.dll System.Xml Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.1433 (REDBITS.050727-1400) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Xml/2.0.0.0__b77a5c561934e089/System.Xml.dll System.Core Assembly Version: 3.5.0.0 Win32 Version: 3.5.21022.8 built by: RTM CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Core/3.5.0.0__b77a5c561934e089/System.Core.dll System.Web.Services Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.1433 (REDBITS.050727-1400) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Web.Services/2.0.0.0__b03f5f7f11d50a3a/System.Web.Services.dll ********** JIT Debugging ********** To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section.

Could someone help me with this? As I am new to .net could someone also tell me when why a temporary class needs to be created in the first place? Thank you very much.

• Remove redundant xml namespaces from soapenv:Body

  - by drachenstern

  If you can tell me the magic google term that instantly gives me clarification, that would be helpful. Here's the part that's throwing an issue when I try to manually deserialize from a string: xsi:type="ns1:errorObject" xmlns:ns1="http://www.example.org/Version_3.0" xsi:type="ns2:errorObject" xmlns:ns2="http://www.example.org/Version_3.0" xsi:type="ns3:errorObject" xmlns:ns3="http://www.example.org/Version_3.0" Here's how I'm deserializing by hand to test it: (in an aspx.cs page with a label on the front to display the value in that I can verify by reading source) (second block of XML duplicates the first but without the extra namespaces) using System; using System.IO; using System.Text; using System.Xml; using System.Xml.Serialization; public partial class test : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string sourceXml = @"<?xml version=""1.0""?> <InitiateActivityResponse xmlns=""http://www.example.org/Version_3.0""> <InitiateActivityResult> <errorObject errorString=""string 1"" eventTime=""2010-05-21T21:19:15.775Z"" nounType=""Object"" objectID=""object1"" xsi:type=""ns1:errorObject"" xmlns:ns1=""http://www.example.org/Version_3.0"" /> <errorObject errorString=""string 2"" eventTime=""2010-05-21T21:19:15.791Z"" nounType=""Object"" objectID=""object2"" xsi:type=""ns2:errorObject"" xmlns:ns2=""http://www.example.org/Version_3.0"" /> <errorObject errorString=""string 3"" eventTime=""2010-05-21T21:19:15.806Z"" nounType=""Object"" objectID=""object3"" xsi:type=""ns3:errorObject"" xmlns:ns3=""http://www.example.org/Version_3.0"" /> </InitiateActivityResult> </InitiateActivityResponse> ";

No I won't post the WSDL, it's hosted behind a firewall, for a vertical stack product. No, I can't change the data sender. Is this somehow automagically handled elsewhere and I just don't know what I don't know? I think I want to do some sort of message sink leading into this method, to intercept the soapenv:Body, but obviously this is for errors, so I'm not going to get errors every time. I'm not entirely sure how to handle this, but some pointers would be nice.
