The CRS-M JSP files exist in the Store.Storefront sub-module in store.war/mobile.

The directory structure under store.war/mobile intentionally mirrors that of Commerce Reference Store. An example of the use case that this setup caters for might be described as follows: A retail customer receives an email from a friend containing a link to a product details page. The retail customer (recipient of the email) then clicks that link, for example: http://localhost:8180/crs/storeus/browse/.... from their mobile device. When this happens, the retailer typically wants to take that customer from the desktop version of that product details page to the mobile-optimized version of that page in order to provide the best possible user experience. This mirroring of directory structure combined with simple mobile browser detection facilitates this forwarding action.
