Spring webmvc chaining viewresolvers gives BeanNotOfRequiredTypeException

Question

I have a simple (sample) web application that i have a problem with if i try chaining multiple viewresolvers. When my application is configured in the way described below, trying to access http://localhost:8080/Library/spring/initApplication will throw the error described below.

It seems as though the InitApplication is erroneously being picked up by the wrong view resolver. If i change the order of the view resolvers everything works, but im still wondering why exactly this error occurs because i cant pinpoint why it happens. Im guessing a configuration issue?

views.properties

pdfPrinter.(class)=library.controller.DummyController

Answer 1

It is certainly because your are mapping your view with a Controller class mate!

pdfPrinter.(class)= you should indicate a View class here!

For example to map a Controller to a jsp View, you will need to proceed like this:

login.(class)=org.springframework.web.servlet.view.JstlView
login.url=/vues/en/login.jsp

Answer 2

have you tried renaming your bean? You may be clobbering an internal bean used by spring
