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. This is discussed in more detail in the section entitled Mobile Interceptor within the General Configuration section.
