23 +In Cayenne raw row fetches are limited to returning columns from a single table. This differs from EOF which allows for any related key path to be fetched.  In Cayenne the qualifier may still reference key paths, they just cannot be returned in the select.  You could consider rewriting complex EOF Raw Row fetches with SQLTemplate in Cayenne.

43 43  Cayenne is agnostic to the specific deployment environment, however it is almost always deployed to a standard Java Application Server (Servlet container) like JBoss or Glassfish, etc. This is an industry standard approach, which has some advantages. Personally, I quite like that the app is entirely contained in a single .war file.
