Retrieve 'relying-party.xml' via HTTP

Yes.  You need to generate the bean (as you did) and then stick a reference to it in shibboleth.RelyingPartyResolverResources/

> <util:list id="shibboleth.RelyingPartyResolverResources">
>        <ref bean="FileBackedRelyingParty"/>
>    </util:list>

> <util:list id="shibboleth.RelyingPartyResolverResources">
>         <value>%{idp.home}/conf/credentials.xml</value>
 >        <value>%{idp.home}/system/conf/relying-party-system.xml</value>
>    </util:list>

You cannot create the same bean twice.  Just remove the file name and replace it with the reference

   <util:list id="shibboleth.RelyingPartyResolverResources">
        <value>%{idp.home}/conf/credentials.xml</value>
        <ref bean="FileBackedRelyingParty"/>
    </util:list>
