 Spring Travel Reference Application
 - demonstrates Spring Framework 3 with Web Flow 2.1
 
-NOTE: 
-At this time this sample is fully functional and upgraded. 
-However, some work is still in progress as listed below. 
-
-Known issues:
-- The sample currently uses an extension for resource handling until mvc:resources support is integrated into Spring Framework 3.1 trunk.  This built-in resource handling support in Spring Framework will supercede the ResourceServlet in the Spring JavaScript module (see SPR-7116).
-- JSR303 support is not yet integrated

-
-TODO:
- - support user registration using Facebook + Spring Social
- - support RESTful authentication from clients in a secure way (SSL + some sort of shared secret? )
