Wcf service returning 404 on method requests

I have an Apache webserver configured in reverse proxy mode which listens for requests on a public IP address and serves them from the internal IIS host. Is there any setting that can be configured in wcf application's web. I'm having similar issues, one of which was the resolution of public and server addresses.

This solved that issue although I still have a couple authentication problems. See this answer for how to create an extension to allow AddressFilterMode. Any to be specified through configuration without requiring code attributes. In the web. In the same endpoint element, set the listenUri attribute to the absolute URL on which the service host is listening.

The way I determine what the default absolute URI the host is listening on is is to add a service reference in a client application which points the the physical server where the service is hosted. The web. I then copy that into the listenUri attribute in the hosts web. I am not sure if this works with message security or transport security.

Since the transport is secure to the ssl load balancer there were no security issues. Unfortunately, there is a bug in WCF where the the base address of imported schemas in the WSDL have the listenUri base address rather than the public base address the one configured using the address attribute of the endpoint.

To work around that issue, you need to create an IWsdlExportExtension implementation which brings the imported schemas into the WSDL document directly and removes the imports. Additionally you can have the example class inherit from BehaviorExtensionElement and complete the two new methods with:.

This will allow you to add an extension behavior in the. And then reference the new endpoint behavior in your endpoint configuration using the behaviorConfiguration attribute. It is also possible in to leave the listenUri attribute blank, however it must be present. Any ] Putting this attribute on service solves the problem.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I've solved the problem. I updated my configuration so that the transport clientCredentialType was set to None and that resolved the issue:. Assuming you are using. NET 4 your service will be listening on one or more endpoints using basicHttpBinding - this is the default if you don't specify an endpoint when using HTTP.

The easiest way to achieve this is to build a proxy using Add Service Reference in a client project and make calls through the generated proxy class - the WCF plumbing will generate the appropriate message and POST it to the service. Learn more.

I think it would be more useful to view it as "retrieving the metadata works but making a service request fails with a ".

Also, how many service contracts does your service implement? My service implements 1 service contract with about 10 operations. In the WSDL what is the address of the service?

WCF service returning on method requests Ask Question.This is a follow-up to my question regarding an "EndPoint Not Found" exception that I posted here and is identical to the problem that this guy posted here.

The only difference is that he was at least able to get the AutoCompleteExtender to communicate with the WCF service when they were both in the same project.

I can't even get that far. It is also worth noting that my ultimate goal is to deploy the solution to a SharePoint site which is why I'm restricted to an older version of the AjaxControlToolKit and.

NET framework 3. However, as of now I can't even get the code to work when I create a brand new website that is completely independent of SharePoint along with the WCF service hosted in the same site so I can avoid any Same Origin Policy issues that might prevent any of this from working.

I was able to get a jQuery autocomplete solution working using the exact same WCF method but for the purposes of this project I cannot use jQuery. This must be a pure C. NET solution. I have already exhausted all the regular suggestions, including:. All of the required HttpHandlers in the web.

I'm all out of ideas. The only thing I can think of is that since I'm performing all of this work on a server that has SharePoint installed that maybe the SharePoint installation made some wonky configuration changes to IIS that is secretly screwing everything up.

I haven't had a chance to try this on a pure machine that doesn't have SharePoint installed but that is likely going to be my next step. Just to reiterate, although I ultimately want to get this working in a UserControl deployed as a SharePoint solution, at this point I can't even get the autocomplete working in a standalone web application that is completely independent of SharePoint, running on the same physical server as SharePoint but as a separate website using a totally different Application Pool.

Now while I don't have much faith in people who provide solutions to problems that involve leaving out things like interfaces because they don't know how they work I don't think the dude would take the time to post something technical like this, claiming that it's possible when it really isn't. And since he was kind enough to try and share whatever knowledge he gained from his experience it would be pretty ungrateful and kind of jerky for me to knock him for not knowing something at this point.

Finally some progress! Now I know that this won't be possible for my real solution because this won't work on UserControls which are my only option when it comes to SharePoint. But still, after all this time I was just so desperate that I needed to see something work. It still didn't work! Yeah, you heard that right. The only difference was that the error said: "Unknown web method GetItemsList. Parameter name: methodName" Crazy, I know.

So I start digging around the web a little more and that's when I stumbled upon this fun little discussion on how to get AutoComplete to work without using a web service. Now keep in mind that I had already read like of these types of posts before but something about this one was different.

In this post the code was using static methods. I figured what the hell. That did it. I had finally gotten AutoComplete to work. The only problem was that I couldn't make my WCF service methods static. So now what? Back to the drawing board So there I was.

After finally tasting success for just a few brief seconds my hopes were quickly dashed once I realized that this wasn't really going to help me at all. Well, at least I got AutoComplete to work in some capacity right? Yeah, this wasn't going to cut it. There had to be something else I was missing. After readings few more posts on the web I stumbled across one that seemed interesting. As I scroll through the various pieces of code something catches my attention.Last post Sep 04, AM by mike4u.

This is happening to me when running from Visual Studio There were some posts similar to mine but the users were not including the servicename. All the function NOOP does is return the text passed as a parameter. SVC and this loads a page alright explaining how to test the service including things like svcutil. I actually made the adjustments on my web config file and interface based on that post and they are very similar. The only different between the code on that post and my own are the fact that I dont have 2 service contracts, but as the author mentions is not a requirement and I would like to keep it simple with only one service contract.

Perhaps the problem I'm having is the way I'm trying to test it through the browser? Any aditional help is highly appreciated. I've replicated the simple calculator wcf project on the URL you provied as a project and when I run it I still get a resource cannot be found on the browser when I try to call the method AddRest throught the browser.

I have no idea what to do next and googling it isn't taking me anywhere. I wonder what I am missing. I also tried to publish the same calculator project to a local IIS 7 server and same behaviour. Any further help or suggestions is highly appreciated. Print Share Twitter Facebook Email.
