Because Commerce Service Center is an agent-facing application, the agent’s internal profile is the active session profile for all requests. To generate customer-specific results from the Assembler, Commerce Service Center swaps the active customer profile for the duration of the call to the Assembler. To do this, Commerce Service Center implements the Assembler’s GenericInvokeAssemblerCallbackImp callback interface. This implementation is configured using the AssemblerTools component:

AssemblerTools.properties:
