Web Flow 2 maps selected view identifiers to files located within the flow's working directory unless otherwise specified. For existing Spring MVC + Web Flow applications, an external ViewResolver is likely already handling this mapping for you. Therefore, to continue using that resolver and to avoid having to change how your existing flow views are packaged, configure Web Flow as follows:

<webflow:flow-registry id="flowRegistry" flow-builder-services="flowBuilderServices">
    <webflow:location path="/WEB-INF/hotels/booking/booking.xml" />
</webflow:flow-registry>

<webflow:flow-builder-services id="flowBuilderServices" view-factory-creator="mvcViewFactoryCreator"/>

<bean id="mvcViewFactoryCreator" class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">
    <property name="viewResolvers" ref="myExistingViewResolverToUseForFlows"/>
</bean>
		

The MvcViewFactoryCreator is the factory that allows you to configure how the Spring MVC view system is used inside Spring Web Flow. Use it to configure existing ViewResolvers, as well as other services such as a custom MessageCodesResolver. You may also enable data binding use Spring MVC's native BeanWrapper by setting the useSpringBinding flag to true. This is an alternative to using OGNL or the Unified EL for view-to-model data binding. See the JavaDoc API of this class for more information.
