The default folder that Nucleus will try to resolve cartridge handlers in is /atg/endeca/assembler/cartridge/handler. The /config subdirectory in that same location contains configuration components associated with the CartridgeHandler components. Similarly, /atg/endeca/assembler/cartridge/handler/xmgr and /atg/endeca/assembler/cartridge/handler/guidedsearch folders contain cartridge handlers that are specific to Experience Manager and Guided Search, respectively, and they also have their own /config sub-paths.

The components in the /atg/endeca/assembler/cartridge/manager Nucleus folder provide additional cartridge support outside of what can be found in the cartridge handlers themselves. For example, the NavigationStateBuilder and NavigationState components build and represent the current navigation state, respectively; the FilterState component represents the state of any filters; and the MdexRequestBuilder component builds MDEX requests.

Note: Currently, the /atg/endeca/assembler/cartridge/handler/xmgr and /atg/endeca/assembler/cartridge/handler/guidedsearch folders are empty and function only as placeholders for future components.
