| http://joda-time.sourceforge.net/ | |
| http://www.ibm.com/developerworks/java/library/j-jodatime.html | |
| All methods should pass a DateTime object instead of Date. Spring will detect if joda is present on the classpath | |
| and handle all converstions to DateTime automagically. | |
| If you do have to pass a date formated string via url, query param, method signature etc, it should always be: | |
| yyyy-MM-dd |

| <!-- VIEW RESOLVERS IN NESTED ORDER | |

| When the extension is | |
| - '.xml', it will delegate to JAXB Marshalling view | |
| - '.rss', it will delegate to the InternalResourceViewResolver's JstlView | |
| - '.html', it will delegate to the InternalResourceViewResolver's JstlView | |
| - '.json', it will delegate to the MappingJacksonJsonView | |
| Second, delegates to BeanNameViewResolve to find a bean id matching the returned View | |
| Third, delegates to InternalResourceViewResolver and tries to find a matching jsp | |
