I tried to use 2 view resolvers:

<property name="order" value="0" />

</beans>
The application always uses only the one with the lowest order and not the other. In the current case if my controller return "someView" the app will respond with The requested resource (/MyProject/WEB-INF/views/someView.jsp) is not available. even if there is "pages/someView.xhtml".
Spring version - 3.2.3
Edit:
If I have 2 methods in controller and methodA returns "viewA" and methodB returns "viewB". And we have viewA.jsp in 'views' folder and viewB.xhtml in 'pages'.
Case1: UrlBasedViewResolver -> order=1,InternalResourceViewResolver -> order=2
methodA -> The requested resource (/MyProject/WEB-INF/pages/viewA.xhtml) is not available.;
methodB -> OK
Case2: UrlBasedViewResolver -> order=2,InternalResourceViewResolver -> order=1
methodA -> OK ;
methodB -> `The requested resource (/MyProject/WEB-INF/views/viewB.jsp) is not available.`;
I think you misunderstood the order priority. The ViewResolver with the highest order is the last resolver in the chain. Since you gave the InternalResourceViewResolver an order of 0, it will be the first resolver in the chain and the InternalResourceViewResolver will resolve the view whatever view name is returned. So, if you want multiple resolvers, the InternalResourceViewResolver must be the resolver with the highest order.
Change the InternalResourceViewResolver order value to 2 :

</beans>
EDIT :
After checking the javadoc, it seems that these two resolvers cannot be chained since the InternalResourceViewResolver is a UrlBasedViewResolver (InternalResourceViewResolver extends UrlBasedViewResolver). Both resolver always match the returned value. I think you will need something custom to be able to do this.
Chage order in InternalResourceViewResolver from 0 to 1. InternalResourceViewResolver must have largest order (lower priority)

I want to update one column of my database. The column name is status and the type is Enum('waiting' , 'accepted' , 'rejected')
I want to update this column when I click on link:

Reject

I can successfully get these two GET values. (id , a). My VacationDAOImpl:

Session session = sessionFactory.openSession();
Query q = session.createQuery("from Vacation where id = :reqid ");

vacation.setStatus(action);
session.update(vacation);

I have seen this approach in this tutorial.
When I click on links, everything looks good. But the column value does not change. Could someone explain this problem?
I have an application setup based on a previous configuration - which was 100% functional. Now I am using maven and am encountering an Error in my controller class which says i must configure Beans.xml.
I'm not sure exactly what this means, as I have my dispatcher-servlet.xml configured in the same way as the functional application.

Edit: Screenshot of error. Which occurs when using the #Transactional annotation.
According to the documentation http://docs.spring.io/spring-framework/docs/3.2.2.RELEASE/spring-framework-reference/html/beans.html#beans-factory-lazy-init the below should not be instatiating MyDatabase yet I can clearly see this is the case in the afterPropertiesSet method of the HibernateDatabase class when debugging. If I remove MyDatabaseEntityManagerFactory then this does not occur. However this should not matter given that MyDatabaseEntityManagerFactory is also lazy - it should not cause MyDatabase to initialise.
Either I'm misunderstanding the part of the docs that say that a lazy bean referencing another lazy bean shouldn't cause it to initialise or there is a fundamental problem in Spring here. Can anyone shed some light on this or possibly suggest an alternative to what I want to achieve?
Thanks.

I am working on web service with spring-mvc 4, I have to make it multilanguage. Like that: if coming url request contains '..?lang=tr' for turkish and '..?lang=en' for english. I read on stackoverflow that <mvc:annotation-driven /> override LocaleChangeInterceptor. But when I remove that, app is not working.And I was using this tutorial. I didnt find a solution for that yet. For configuration below, messages are always in english even if I switch language. Furthermore I need to get lang messages in java instead of jsp also. But it always return default message there in java class when I syso. I messed up here. and asking for your help.
#Autowired
private MessageSource messageSource;
Locale locale = LocaleContextHolder.getLocale();
String msg = messageSource.getMessage("deneme", null, "Deault Message!", locale);

add this to your xml to register your localChangeInterceptor and it will work

You are missing the actual Thymeleaf jar. You included the Spring jar that provides the integration but you missed the actual implementation of it.
Download the jar from here
