Spring webflow 2 - url mapping not working

Question

I'm using spring mvc 3 along with webflow 2. I have been following online resources and have been trying to get an example working. I am unable to get the webflow url mappings to work. It is only the webflow that is not working, the mvc part is working fine.

The error I keep getting is: No mapping found for HTTP request with URI [/Project2Admin/pizza] in DispatcherServlet with name 'appServlet'

I have pasted my servlet-context.xml below.

Your help is much appreciated! Odie

version of servlet_context.html with only one view resolver (jstl view reolver). Both the mvc and webflow parts did not work with this setup.

Answer 1

Try changing your FlowHandlerMapping to

<beans:bean
    class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
    <beans:property name="flowRegistry" ref="flowRegistry" />
    <beans:property name="order" value="-1" />
</beans:bean>

You are using the annotation driven configuration for Spring MVC which registers a default HandlerMapping for you, and I suspect it doesn't fall through to the next HandlerMapping. This has previously been reported as an issue. You want the WebFlow FlowHandlerMapping to come first - so you set the order to -1. This is what we have in our configs.
