I have made a small log service that i want to publish to a subdomain on my webhotel. I make the wcf service and test it locally - no problem. I then go to the [Build] menu and choose [Publish], type in my FTP location and publishes it to the location. No problems.
The problem arise when i need to use it, i try to navigate to the .svc file but gets this error:
This collection already contains an address with scheme http. There can be at most one address per scheme in this collection.
Parameter name: item
What am I doing wrong?
That's because of your IIS configuration. This has already been discussed here: WCF service startup error "This collection already contains an address with scheme http"
Solved! The problem is that i cannot access the IIS configuration, since its on a hosted environment. The solution is described on my blog, since i had so much trouble getting this to work.

After Configuration server Juddi in Eclipse and create environment variable
we get Problem to access to page Gui user and admin and tomcat interface :
I think you are looking at something like :
message java.lang.IllegalStateException: No output folder
I would check the Tomcat logs, the permissions of the user you are running tomcat under, and check the directory that you have installed your tomcat into.
Do not even try to use UDDI
these days. People are moving towards semantic web services ,UDDI is out of the scene.
WSMO and OWL-s are major initiatives for semantic web services. These solutions can provide more precise results.
Here's a few
mDNS/Bonjour/Avahi - can be used to share endpoint information for a web service, or anything else using a TXT record
WS-Discovery - supported by CXF and WCF, shares implementation of a specific interface
ebXML - had a component similar to UDDI

I hosted silverlight application iis and that can be accessed in multiple ways..
When I access using Qualified name of server IP address IT WORKS fine:
http://[QUALIFIEDNAME]/WebUAT/App.aspx
When I access using IP address like below:
http://[IPADDRESS]/WebUAT/App.aspx
It gives error below:
[Async_ExceptionOccurred]
Arguments:
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.1.20913.00&File=System.dll&Key=Async_ExceptionOccurred StackTrace : at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary()
Follow these,
(i) Try to use fiddler and find the request which is making crossdomainpolicy xml request.
(ii)Check whether it is failing, if so add the crossdomain and clientaccesspolicy to the root folder of your Application
(iii)Check whether the service which is invoked by your application is blocked by firewall.
I have REST service application which is hosted in an IIS 8 in a Windows 8 PC. When I request the service I am getting an error as follows ... HTTP Error 404.0 - Not Found.
Here is the detailed error message.
HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
Most likely causes:
•The directory or file specified does not exist on the Web server.
•The URL contains a typographical error.
•A custom filter or module, such as URLScan, restricts access to the file.
Things you can try:
•Create the content on the Web server.
•Review the browser URL.
•Create a tracing rule to track failed requests for this HTTP status code and see which module is calling SetStatus. For more information about creating a tracing rule for failed requests, click here.
Detailed Error Information:
Module IIS Web Core
Notification MapRequestHandler
Handler StaticFile
Error Code 0x80070002
Requested URL http://IP.com/Wining/RService.svc/general
Physical Path C:\inetpub\wwwroot\Wining\RService.svc\general
Logon Method Anonymous
Logon User Anonymous
Any help on this would be greatly appreciated.
There are myriads of possible causes. In general, the target resource at given URL is not found, so it may be simply missing, misconfigured, not started, etc. First - check the server logs, they usually contain more detailed information about the issue.
Also, please doublecheck that the service really is up and running. Connect to the www server and check it via localhost not ip.com.
I'm not an expert, but judging from the snippet you provided, it seems to be WCF service, the Handler: StaticFile seems very odd. It seems like the IIS misinterpretes your request as a StaticFile (a resource read from the disks and just passed-through without any further processing) which for me seems perfectly wrong.
You may have not installed the service properly, or have url mappings and/or handlers messed up, or you may even have NET/ASP framework not properly installed.. What have you installed first? .Net or IIS?
check similar questios, there are many.. for example:
WCF on IIS8; *.svc handler mapping doesn't work
HTTP 404 when accessing .svc file in IIS
I had to enable HTTP Activation in .NET Framework 4.5 Advanced Services > WCF Services (running on WIndows 2012) and after an IISReset it worked fine.
I have added a WCF service to an existing ASP.Net web project on our test website (only accessible on company network). I can access the service by typing the URL in a browser, but if I add a service reference to a web project, I get a runtime error that 'the remote name could not be resolved'.
In my web.config, I have the bypassProxyOnLocal binding attribute set to 'true' (we use a proxy on the company network), but it seems as though our test domain is not recognized as a local domain (or recognized at all, really). Again, this is only when I add it as a service reference. Obviously the domain is valid, because I can add it as a service reference, and can event paste the URL into a browser, and it works. I just get a runtime error after I add it as a service reference. Anyone have any advice?
According to MSDN WSHttpBindingBase.BypassProxyOnLocal Property, "An Internet resource is local if it has a local address. A local address is one that is on same computer, the local LAN or intranet and is identified, syntactically, by the lack of a period (.) as in the URIs "http://webserver/" and "http://localhost/".
If your test domain is "http://test.mycompany.com/", then it won't be viewed as a local address. Perhaps using "http://test/" in this case would work?
Finally got this resolved. The request was somehow being blocked by the company network.
I have a silverlight project that calls into a wcf service. Everything works fine on my local machine.
However when I deploy to a virtual machine, with the exact same query the wcf service returns, but the result is empty.
I've tried debugging, but have not been able to get it to break in the wcf service.
Any ideas what the problem could be, or how I could go about debugging it?
Thanks
I figured out what the problem is, but am not sure what the solution is.
In my silverlight project the wcf service I am referencing is http://localhost/.../SilverlightApiService.svc
I used fiddler on my vm to see the request that was made and instead of trying to contact the above service, it was trying to contact:
http:///.../SilverlightApiService.svc
So, for some reason my machine name is getting inserted in there instead of localhost. Any thoughts on this would be appreciated.
I had this exact problem when deploying to amazon ec2 - The machine name for the service was being returned in the wsdl rather than the dns.
There were a couple solutions (one involved creating static wsdl - yuck!)
But the other was creating a sort of factory pattern for the service

The slight downfall with this is that although it works - if you change the location of the server, you will need to remember to update your config - Which although isn't hard, it's easy to forget to do.
Can you give us a bit more information? What kind of binding are you using? What does the service config and the client config look like? Where do you get your data from that gets returned? Could it be the service on the VM just doesn't get any data? (e.g. queries a database that just doesn't have the data requested?)

I have had that happen before. I would try this. Set you start page as the web service file and run the app. Then set the start page back to your default page. Then update all the server references in your SL project. Recompile everything and republish. This has helped me a bunch of times in the past.
I figured it out.
Basically my machine name was hard coded in my ServiceReferences.ClientConfig file in my silverlight project.
What I had to do was specify programmatically what url to use for the service reference when instantiating my service client:
System.ServiceModel.EndpointAddress address = new System.ServiceModel.EndpointAddress(new Uri
(Application.Current.Host.Source, "../WebServices/SilverlightService.svc"));
ServiceClient serviceClient = new ServiceClient("BasicHttpBinding_IService", address);
I figured out what the problem is, but am not sure what the solution is.
