I have a business resource for which operations (create, update, list, ...) are distributed over several services. I use the following configuration:

<jbi:jbi ...>
   <jbi:services binding-component="true">
      <jbi:consumes interface-name="inscription-cantine:inscriptionCantine">
         <cdk:timeout>${municipalite.timeout.clt-services.qf}</cdk:timeout>
         <cdk:mep xsi:nil="true" />

            </rest:operation>
         </rest:mapping>
      </jbi:consumes>

         </rest:mapping>

With the first section 'consumes' a servlet is created. A check prohibit to create another servlet with the same base path.

Instead of creating a second servlet, the first one should be updated with configuration of other operations
