so we always use the latest in the classpath

RSS is becoming outdated, JSon is a better example

Happens since introduction of new mvc namespace tag for
content-negotiation

There seems to be a conflict between the following:

1) New MVC namespace syntax:
<mvc:content-negotiation use-not-acceptable="true">
	    	<mvc:default-views>
	      		<bean class="org.springframework.web.servlet.view.JstlView">
	      			<property name="url" value="" />
	      		</bean>
	    	</mvc:default-views>
	  	</mvc:content-negotiation>

2) Inside my Unit test:
ResultActions actions =
this.mockMvc.perform(get("/vets.xml").accept(MediaType.TEXT_XML));
        actions.andDo(print()); // action is logged into the console

        actions.andExpect(status().isOk());

We were planning to create a ‘help’ but it never happened

Took that opportunity to use custom tag (14 lines versus 2 lines)

Previously was in session scope (doesn’t scale as well)

- Now using namespace, much simpler (11 lines instead of 27)
- Just a minor issue with:
<bean class="org.springframework.web.servlet.view.JstlView">
	<property name="url" value="" />
</bean>
(should investigate later if we can remove “url” attribute

Also had to make changes because Spring now uses com.rometools for RSS
feeds
See here for more details: https://jira.spring.io/browse/SPR-11893

 * The old datatables-servlet2 dependency has been removed from the pom.xml
 * Some attributes have been renamed (e.g. paginate => pageable)
 * Starting from the v0.10.0, all web components (servlet, filter) must be explicitely declared in the web.xml file. That's why I added the following declaration: DandelionFilter, DandelionServlet and DatatablesFilter
 * Added a new datatables.properties file in order to disable the asset management brought by Dandelion-Core. This is equivalent to the old cdn=true table attribute

jdbc.properties was renamed to data-access.properties, but this file still referred to the old name.

Any method you define in an interface is by definition public

Test in error with french default Locale:
org.junit.ComparisonFailure: expected:<[ne peut pas être vide]> but was:<[may not be empty]>
	at org.junit.Assert.assertEquals(Assert.java:115)
	at org.junit.Assert.assertEquals(Assert.java:144)
	at org.springframework.samples.petclinic.model.ValidatorTests.emptyFirstName(ValidatorTests.java:39)

adding explicit reference to default profile because it doesn't seem to work on on some environments

Spring MVC should server static resources (*.html, ...) located in src/main/webapp instead of returning "404 Not Found"

App should be as simple as possible for beginners
