Getting started with Spring Framework 3.1

[Marcos Vidolin]

Hello guys,

I'm trying to build a Maven project with JSF 2 and Spring Framework 3.1 running on Jetty.
I have a class with a @Controller but when I try to access a method declared at this class I got a erro: caixaController resolved to null


It seems the class was not loaded.

These are my configurations files:

pom.xml

	<properties>
		<spring.version>3.1.0.M2</spring.version>
	</properties>

@Controller
@Scope(value = WebApplicationContext.SCOPE_REQUEST)

I am not sure I understand what you really meant. What is the code which you tried to access? Or did you type a URL in browser and the server returns an exception?

Please be more clear.
