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 - JPABookingService findHotels(SearchCriteria criteria) is currently vulnerable to HQL injection - Use of <persistence-context/> in the hotels/booking flow should be removed in favor of detached objects
