I have a webservice [call it S1] exposed and clients call that service and get back response.So good so far.
I have to change my WSDL a bit [for some very odd reasons] but i dnt want clients to see the change. So my idea is to intercept the soap request somewhere b/w server and client and interceptor should modify the soap request and forward to the server.Similarly on response , again interceptor should intercept the request and change some property name and send it to the client.
Any idea how to do this? One approach IMO is to use handlers but here i dont have control over how server generates service from WSDL.
How can ESB help in this?
Please see its realtime application with huge requests to and from server!!!
An ESB like Mule ESB can help by acting as a proxy for your web service.
Can you not write a new web service with the new wsdl, then alter the old web service to simply call the new web service. A bit like overloading a method. That way you can have V1 and V2 web services.

I have not configured an environment before. However, I have worked in an environment which is restful and basically calling the service was as bare-bone as calling the service URL using AJAX calls from the javascript.
Now, I am in a WCF environment and I am laying out the service here. It sounds like WCF requires a lot of configuration on the client side including a client proxy class (I guess for each service that we want to call?)
This is a lot of boilerplate code that I am going to write here. That is fine but out of curiosity I am just wondering that what is advantage of using WCF and its client Proxies as oppose to simple RestFUL AJAX calls which will return JSON objects to your Javascript. Also this produces more questions like:
Can I use WCF with javascript/AJAX environment? Because there is no way that Javascript is going to be able to create a proxy for it
Even ASMX model was not requiring proxy. Then why WCF added this proxy? what advantage does WCF/proxy have compared to ASMX without any proxy?
So this is in relation to my question here.
So I have an existing wcf service running already, hosted on IIS. I created a Router Service that will do some XPath filtering on the header. So if the header is match then go to service1.
Now, I hosted my Router Service on IIS and I can access it like http://iis.com/myrouter/router.svc/ and give me this wsdl stuff. Now when I try to request a service method on service1 like this http://iis.com/myrouter/router.svc/general/getMyMethod?blah=blahblah. It gives me a 404 error. I used fiddler by the way.
On my request through fiddler I added my custom header like "service_version:1". I used a namespace by the way on my <namespaceTable> but I don't know how to append it on my request. Anyway, my main concern is how can I make my Router Service work on IIS?
Update: I am using System.ServiceModel.Routing.RoutingService by the way. So what I am trying to accomplish is Routing Services.
Your help is greatly appreciated.
You are likely facing this. A SOAP service can't be accessed that way because it relies on the SOAP package. Here is another article that should lead you down the right direction. However, the direction it leads you down is that testing a SOAP service by hand is not to be desired and probably a futile effort.
However, one note is that it leads you to use the WCF Test Client - that's the best direction to go my friend and it's very easy to use. Provide the URL and it will do the rest.
Invoke soap wcf service in Fiddler like in Wcf test client
Accessing the RESTful Endpoint
If you're trying to test the RESTful endpoint then the issue is likely surrounding the routing that is configured. Please refer to this link for assistance - make sure you're setting up your service the same because the attributes they use build the routing properly. Remember that you're not going to reference the RESTful endpoint with the same address as the SOAP endpoint.

Hosting WCF soap and rest endpoints side by side
I have some clients calling my asmx service and I figure out to change my asmx to a Wcf service.
How can my asmx clients call to my Wcf service without modify the client application?
Maybe just a few changes in the config file...
I can't expect than they compile their applications.
The following article illustrates a detailed guide on how you could achieve that.
You need to support basicHttpBinding in your WCF server and provide new URL to your basicHttpBinding endpoint to callers.
Callers only need to change URL they use.
Everything should happen behind the scene for them.
I would like to know, if I need to generate client proxy for self-hosted WCF within Windows Form?
Basically what I'm trying to do is, post Html form to WCF operation. I have checked WCFClientTest to validate that my WCF get picked up including its operations, which it does.
But when I try to post data to Operation, I get Error 400 Bad Request.
Thanks,
I am doing integration testing of my system with a 3rd party web service. They have provided the WSDL and the XML soap response packets but the web service hasn't been built yet. I am using WCF to call the web service.
Any suggestions on how to write the end-point to send back the response contained in the XML file?
I know I can generate the service side from the WSDL but I'd like to verify the integration using the supplied XML packets.
I'm sure there's a more technical way, maybe using an interceptor to replace the soap response form your mock service, but a quick hack might be to just create the Mock service with SvcUtil, and grab your own SOAP response off the wire with fiddler or wireshark and compare the responses.
I think SOAP UI serves your purpose. Using SOAP UI you can have a dynamic behavior to the service you want to mock. For example you might want to:
Read some data in a request and use its value to select which response to return
You can also virtualize the services multiple SOAP request and response very well using ITKO/CA LISA.
LISA will record live service requests and responses, and create a virtual test bed to remove the team's dependency on live, connected systems or fully replicated test beds
You can also mock using concrete WSDL of target system using LISA
