Endpoints when adding assembly references?

I have a WCF service that uses a reference to a class library. Classes in that library do things like interact with a database. I was testing my service (which compiles with no errors) using restful calls through a browser and it just displays a page that simply says "Endpoint not found.". I'm assuming that this is related to the fact that the library has references to connection strings and appsettings etc (which i normally have to include in the applications that use this library). So what I'm having trouble finding is how to properly configure the wcf service to work with this library. I tried simply adding the connection strings and appsetings to the wcf web.config but that doesn't seem to help. I feel like it is just about adding reference to the library through the endpoint section of the service. But I'm lost there. Any help is appreciated. Thanks

<system.serviceModel>
    <services>
      <service name="RestService.RestServiceImpl" behaviorConfiguration="ServiceBehavior">
        <endpoint address="" binding="webHttpBinding" contract="RestService.IRestServiceImpl" behaviorConfiguration="web">

        </endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name ="ServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

ok so I got it working. It APPEARED to be an issue with the host address. I recreated the project as a Service Library instead of a Service Application and I noticed a couple new fields in the default config. One of which was for the host. When I set the base address, everything started working just hunkydory. Here is the config:

<system.serviceModel>
<services>
  <service name="ServiceWithLibraryTest.UtiService">
    <endpoint address="" binding="webHttpBinding" contract="ServiceWithLibraryTest.IUtiService" behaviorConfiguration="web" />        
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8732/ServiceWithLibraryTest/UtiService/"/>
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="False"/>
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
</behaviors>

I'm kind of new to WCF and from what I understand, it is notorious for the config constantly being a head scratcher. I'm still working on wrapping my head around endpoints, but I'm starting to get a better understanding of how endpoints are just the means of exposing the service and behaviors being how they are communicated. Then of course, rest services add a whole new layer to that. I appreciate the thoughts :)
