Routing WSE 3.0 SOAP request through NAT - c#

I'm trying to send a soap request to a WSE 3.0 service but can't get the request to work.
It's working great when there is a direct connection between computer A and B. When there is a NAT device between them (A -> NAT -> B), I get an error in the event log on computer B:
Message Dispatch Failure:

</soap:Body>
</soap:Envelope>
I also get a exception from the service proxy class in C#:
GetMachineQueue Exception: System.Web.Services.Protocols.SoapHeaderException: Destination Unreachable
From what I understand the problem is that the "wsa:To" tag is pointing at the NAT device and not the final destination. But I have to point the request to the NAT to come to computer B.
The NAT device uses port forwarding to forward the request to computer B. When we have a A -> B setup this code works fine:
EquipmentService client = new EquipmentService();
var machineAddress = GetUri(sMachine);
client.Url = machineAddress;
client.GetMachineQueue(sMachine);
But that doesn't work when doing A -> NAT -> B. I have temporarily solved this by adding this code:
EquipmentService client = new EquipmentService();
var (machineAddress, natAddress) = GetUri(sMachine);
client.Url = machineAddress;
client.Destination.Via = new Microsoft.Web.Services3.Referral.Via(new Uri(natAddress));
client.Destination.Address = new Microsoft.Web.Services3.Addressing.Address(new Uri(machineAddress));
client.GetMachineQueue(sMachine);
I feel this is a bad way of solving the problem tho since what happens if there are more nodes that is has to pass before reaching its destination? Is there any way I can configure the request to automatically "redirect" or something?..

Send special character in SOAP request

I am encountering issue sending a SOAP request containing special char to a Web Service. I have a WinForm textbox where user input text such as "1€" for instance. Then I call a WS method which aims to store the data into database.
I implemented the IClientMessageInspector in order to intercept the
SOAP inbound/outbound messages, and noticed that the string sent to server is "1▒" :
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header>
<Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">urn:MYWebService#insertData</Action>
</s:Header>
<s:Body s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<q1:insertData xmlns:q1="urn:MYWebService">
<note xsi:type="xsd:string">1▒</note>
</q1:insertData>
</s:Body>
</s:Envelope>
Therefore data stored in database table is "1?".
I did many tries, such as using WebUtility.HtmlEncode without success. I am wondering whether I have to do an action on client side or server one. Can you please advise me about any suggestion to follow?
What was the HtmlEncode returning for you? I would suspect something like
<note xsi:type="xsd:string">1€</note>
should have some effect.

Converting a WCF (svcutil) C# code into the corresponding SOAP envelope POST request

This is how I'm currently (and successfully) connecting to a WCF web service in C#. I do not have any control over this web service as it's not developed by me, so I cannot change it. Here is the C# code I use:
WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.TransportWithMessageCredential;
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
binding.Security.Message.NegotiateServiceCredential = true;
binding.Security.Message.AlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Default;
binding.Security.Message.EstablishSecurityContext = true;
EndpointAddress endpoint = new EndpointAddress("<address>");
fooClient client = new fooClient(binding, endpoint);
client.ClientCredentials.UserName.UserName = "the_username";
client.ClientCredentials.UserName.Password = "the_password";
//fooClient class came from running
// svcutil.exe https://<thedomain>/foo/foo.svc?wsdl
//I now work with fooClient, call methods on it, etc.
I want to connect to the web service without C# - by manually creating a SOAP envelope and doing a POST request on the endpoint. I tried doing a POST request that looks like this:
POST /foo/foo.svc HTTP/1.1
Content-Type: application/soap+xml; charset=utf-8
Host: <thedomain>
Connection: close
User-Agent: <my user agent>
Content-Length: 416
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
<soap12:Body>
<someWebServiceFunction xmlns="http://<thedomain>/foo/foo">
<someParameter>some parameter value</someParameter>
</someWebServiceFunction>
</soap12:Body>
</soap12:Envelope>
But this does not work because the credentials are missing. (I get an error back: "BadContextToken", "The security context token is expired or is not valid. The message was not processed.")
My question is, how do I add credentials to my SOAP envelope / HTTP request? I tried doing plain HTTP Basic Auth (in the Authorization HTTP header), but this continues to give me the same "BadContextToken" error.
There are two simple ways to trouble shoot your issue:
If you are using Visual Studio, in debug, send the request and intercept what is the detailed content in the request, and you can simulate it using plain HTTP POST.
If you can use SoapUI, you can target the service using SoapUI and send one working request, in the raw tab, you will see what's the accepted request with credentials.

Service Response to WCF Includes Duplicate Namespace and Tag Prefix

Question:
Why would I receive a SOAP response fragment that contains a duplicate tag prefix namespace?
Why would I receive a different response fragment in SoapUI versus a WCF client using the exact same SOAP request?
Context:
I am calling a third-party, Java based web service with a WCF client. The SOAP fragment response sent from the third party WS contains a duplicate namespace and tag prefix for the soap envelope on the Fault tag line when calling with an incorrect value that results in a fault response. This causes the WCF to throw a CommunicationException with an innerException of XmlException which cites the following as the error:
Start element 'faultcode' from namespace '' expected. Found element 'SOAP-ENV:faultcode'
from namespace 'http://schemas.xmlsoap.org/soap/envelope/'.
This error message leads me to believe the duplicated namespace in the SOAP fragment is the culprit. The weird thing is, using the exact SOAP request sent from the WCF client to the web service in SoapUI does not result in this namespace being duplicated in the SOAP response fragment.
The WCF client is using a basicHttpBinding.
Please see below for SOAP fragments of the request, response through WCF, and response through SoapUI.
Request sent by both WCF and SoapUI:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<TargetId></TargetId>
</Request>
</Search>
</s:Body>
</s:Envelope>
Response received by WCF client:

<SOAP-ENV:Body>

</SOAP-ENV:detail>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Response received by SoapUI:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<SOAP-ENV:faultcode>SOAP-ENV:Server</SOAP-ENV:faultcode>

<SOAP-ENV:detail>

</fns:fault>
</SOAP-ENV:detail>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The problem is not the duplicated namespace declaration. The problem is in this bit:
<SOAP-ENV:faultcode>SOAP-ENV:Server</SOAP-ENV:faultcode>
<SOAP-ENV:faultstring>Invalid action parameters</SOAP-ENV:faultstring>
On the SOAP Specification, the faultcode and faultstring elements are in the empty, default namespace, not in the "http://schemas.xmlsoap.org/soap/envelope/" namespace. So it really should've looked something like this:
<SOAP-ENV:Fault>
<faultcode>SOAP-ENV:MustUnderstand</faultcode>
<faultstring>SOAP Must Understand Error</faultstring>
</SOAP-ENV:Fault>
So looks like this service in particular is not being compliant with the SOAP 1.1 (or 1.2 for that matter) specification.

Error in Amadeus Service: A header representing a Message Addressing Property is not valid and the message cannot be processed

While trying to invoking my Amadeus Fare_masterpricetravelboard Service using SoapUI like mozila poster, Google restclient app, or my .net code, it returns the following error message:
A header representing a Message Addressing Property is not valid and the message cannot be processed
The same webservice is working fine in SOAP UI Tool.

Be sure that the url of the web request matches the value of the tag "add:To", including letter case.
Probably you are developing in .net and, even if you set the url in the same letter case, the request will be sent to the address in lowercase. So nodeD1 become noded1 in http layer but remains nodeD1 in soap envelope. Be careful to use lowercase or uppercase in both fields
This could be because of SOAPAction as well.
In my case ,
Soap UI internally uses : http://webservices.amadeus.com/{{orgCode}}/FMPTBQ_21_4_1A
when generating stub, orgCode is missed it came as http://webservices.amadeus.com/FMPTBQ_21_4_1A
After changing SoapAction explicitly in the code, started working.

How to create an otrs ticket using a soap request .Net

I have created a solution.
Added the WSDL file.
This keeps on popping following error "Length Required".
I tried with the above code in the post (, but seems that is not working.
Where do we specify the Operation name here?
-- Anand
Before getting it to work in java c# .net etc you need to get the SOAP xml correct.
The operation name is added as a tag in the soap body element.
Say for example your operation name is createMyOTRSTicket as specified in OTRS UI Web Service.
The SOAP request sent should look something like this like this:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<createMyOTRSTicket xmlns="WS">
<UserLogin>MyUserName</UserLogin>
<Password>MyPassword</Password>
<Queue>'some queue name'</Queue>
<State>'some state name'</State>
<Priority>1</Priority>
<!-- ...etc.. -->
<Article>
<Subject>some subject</Subject>
<Body>some body</Body>
<ContentType>text/plain; charset=utf8</ContentType>
</Article>
</createMyOTRSTicket >
</soap:Body>
</soap:Envelope>
See the API for what elements are require and which are optional for TicketCreate here
The Soap Message should be sent to /nph-genericinterface.pl/Webservice/CreateTicketWS where CreateTicketWS is the name of the Web Service.
Also note that the attribute xmlns="WS" refers to the Namespace you specify in "Network Transport" config also locatred in the GenericInterface Web Service Management.
I hope this helps you. Sorry it might be a bit confusing for someone new to SOAP and OTRS.
