Calling webservice from WCF service - wcf

Question

I am having an issue consuming a webservice (c#.net) from a WCF service.
The error i am getting is EndPointNotFoundException "TCP error code 10061: No connection could be made because the target machine actively refused it"
I wrote a unit test to check if i could send a request to the web service and it worked fine
[The unit test is using the same binding configuration as my WCF service]
The web service and WCF service (client) have basichttp binding.
Did anyone had similar kind of issue calling a webservice from a WCF service?
The service Model section is as follows
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="DataService" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:10:00" sendTimeout="00:05:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
<message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://10.22.33.67/Service/DataService.asmx" binding="basicHttpBinding"
bindingConfiguration="DataService" contract="Service.DataService" name="DataService"/>
</client>
<services>
<service name="TestToConsumeDataService.WCFHost.Service1" behaviorConfiguration="TestToConsumeDataService.WCFHost.Service1Behavior">
<!-- Service Endpoints -->
<endpoint address="" binding="basicHttpBinding" contract="TestToConsumeDataService.WCFHost.IService1">
<!--
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
automatically.
-->
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="TestToConsumeDataService.WCFHost.Service1Behavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
The unit test project is also using the same service model section and it works. The only issue is while calling the service from another WCF service. Could you please suggest.

Answer 1

You mentioned "webservice" and "WCF service" - so the "webservice" is a old-style ASMX web service??
How is your WCF service hosted? In IIS? Do you have the necessary endpoint information for the webservice you're calling from WCF inside your web.config ??
Can you show us your relevant configs, e.g. the <system.serviceModel> section of your web.config (or app.config, if you're self-hosting the WCF service), please?
The error means there's either no webservice listening at the address you're using, or you don't have access rights to it. Are you missing some security or something?

It looks like there is some configuration that you need to call your web service.
This configuration is correct in the configuration file of your unit test.
But it is not correct or missing in the configuration file of your WCF service.
When you have two dll's where one calls the other, then it is the config file of the first dll that is used. However, when you go over a WCF hop, it is the config file of the WCF service that takes over.
Hope this helps
