asp.net webservices : Preventing Escapes in Post
Hi,
I am trying to consume the webservice which is written with Java through the provided wsdl & xsd definitions. However there is a slight problem. Problem is, they are expecting a clean XML but .NET converts my query XML into escaped form into the SOAP body which makes their service to respond in the following form: <?xml version="1.0" encoding="utf-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><soapenv:Fault><faultcode>soapenv:Server.userException</faultcode><faultstring>java.lang.IndexOutOfBoundsException: Index: 0, Size: 0</faultstring><detail><ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">trajanoxp</ns1:hostname></detail></soapenv:Fault></soapenv:Body></soapenv:Envelope> Now my question is: Is there a way to prevent this escaping? Or I must write all the soap from string and send the whole XML string manually? Thanks for your help in advance. -- SevDer www.sevder.com

This obviously has to do with the way that you are using .NET. Please tell us how you are producing the XML. Also, is there a reason that you didn't just consume the web service by using Add Web Reference in Visual Studio? -- John Saunders [MVP]
Hello John,
Thanks for the reply. I think you should check this again. I've learned that .NET actually escapes the inner XML to prevent bad XML forming on some cases. And as far as I learned this is the behavior of .NET not the way that I use. Additionally the otherway around problem is there too. For your webservice to work with other applications, you will need to escape all received inner XMLs as they (like Java) send it as nonescaped form. Also I added as web reference and I am trying to make the webreference to work not any other way. If I cannot make this working, then I will have to POST using regular HTTP Post and not use wsdl reference. And their WSDL defined method calls does not accept structured objects but simple and generic object which actually is simple XML. The bottom line is, I am just trying to learn if there is a way for .NET to not to escape my request XML while sending over! -- Sevket Seyalioglu CTO www.kbstours.com [quoted text, click to view] "John Saunders [MVP]" <john.saunders at trizetto.com> wrote in message

I promise you that, as a general rule, .NET doesn't prevent people from using XML by escaping it. You are clearly using it in a way that other developers do not use it - they are succeeding and you are failing. Please post some code showing us how you are using XML. Among other things, your mention of "inner xml" is frightening. You are doing something very strange. Please look at some of the following links on Web Service basics.

Thanks for John's input.
Hello SevDer, I agree that the problem should be quite specific to the service and its requirement on the SOAP message format. Would you provide some further information on the service(such as the format and structure of the SOAP message it expects from client). Normally, for any string value inside XML document(include SOAP envelope), it have to escape those special characters so as to ensure the validity of the document. If the customzation requests for your scenario does be reasonable, we may look for some ways to customize the client proxy class. Please feel free to post here if there is anything we've missed.

Hi Steven,
The webservice (not the native .NET webservice) which is written in Java is expecting the string in XML format without being escaped. Its not my service, I am just trying to consume it. So how can I customize it in the proxy class? What are the basics? Are there any samples or guides? -- CTO www.kbstours.com [quoted text, click to view] "Steven Cheng[MSFT]" <stcheng@online.microsoft.com> wrote in message

Hi John,
It is not my first time using webservices. Please see Stevens comments too. He clearly mentions that .NET needs to do this escaping as a safe guard which I am trying to prevent. And this is not an issue when both ends are .NET code but when one of the end is not .NET like Java then you have a problem. I've spent good amount of time to see where I fail and finally find this out by writing the TraceExtension to the webservice call. So if you can find anything for this, please let me know.

He clearly mentions that .NET needs to do > this escaping as a safe guard which I am trying to prevent. You have misread Steven's post. The escaping he's referring to is within text nodes. That is, within an attribute value or within the text value of an element. For instance: <element attr="<x>">Includes "&"</element> The main portion of your SOAP messages should not be getting escaped. If it is, then you are doing something very unusual. As a hint: note that there are many questions about web services on this newsgroup, and yet no questions about how to not escape SOAP messages. Your problem must be unique to your code. Please post some of your code, so we can see what is going on. In particular, if you can create a smaller example that reproduces what you're seeing, and then if you could post the WSDL and client code for that smaller example, then we'd be able to see what you're doing to produce escaped XML. Without that, we're just guessing. And, please let me reiterate that this may very well have to do with the fact that you are manipulating OuterXml. It should be unnecessary to deal with the string representation of XML in a web service. Here are some basic references on Web Services in .NET: Overview of XML Web services: http://msdn2.microsoft.com/en-us/library/7bkzywba.aspx A walkthrough of building a basic XML Web service: http://msdn2.microsoft.com/en-us/library/7hs6sw69.aspx A walkthrough of building a basic client application: http://msdn2.microsoft.com/en-us/library/hk7y1596.aspx Serializing objects with XML web services http://msdn2.microsoft.com/en-us/library/564k8ys4.aspx -- John Saunders [MVP]
Thanks for the reply,
So based on your further description, I know that the java webservice actually expect a webservice SOAP message which contains an XML fragment (which is not escaped) as part of the SOAP body itself. I'm afraid this doesn't quite conform to XML webservice standard. Because for any method's data(parameters or return value) ,if it contains particular charaters, it should be escaped. For example, the SOAP body xml document is used to represent a request message of a method call, however, if your parameters data is a XML fragment and not escaped, how can we know which part of the xml document is the method body and which part are parameters data? Therefore, for the scenario here, I think it would be better to manually post the XML soap message through some network components such as HttpWebRequest as it can let you freely control the underlying tranfered message data. How do you think?

Thanks Steven,
I was actually looking for answer and you've given that to me. At least I do not need to look for more. I also during that time, given up and started developing by my own posting as I didn't see any chance.

Thanks for your followup,
It's a pity that we can not do more here with the built-in features. Also, through XML webservice is designed to provide heterogenious platform interop and recommend document-literal and WSDL/SOAP restricted message formats, there are still many realworld services which do not quite conform to that, that makes the interop difficult :(. Anyway, if you need any further help later, please feel free to post here. Thanks for your posting!
