Calling a controller method from state spring web flow.

[Lucky J Verma]

Hi all,
I am new to SWF2 and working on a flow at the end of which PDF should be displayed inside window.
Since all the execution is controlled by states in xml, i cannt figure out how to break it out to follow controller method which can stream pdf response to browser
I followed this tutorials:
http://duckranger.com/2010/12/display-a-generated-pdf-from-within-spring-webflow/
But my webflow configuration is different and i am not at a point where i can comfortably change the config.

My config:

<beans
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:webflow="http://www.springframework.org/schema/webflow-config"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
						http://www.springframework.org/schema/webflow-config http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.0.xsd">

	<webflow:flow-registry id="flowRegistry" flow-builder-services="flowBuilderServices" base-path="/flows">
	    <webflow:flow-location-pattern value="/**/**-flow.xml" />
	</webflow:flow-registry>

	<bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
	    <property name="flowRegistry" ref="flowRegistry"/>
	    <property name="order" value="0"/>
	</bean>

	<bean id="flowController" class="org.springframework.webflow.mvc.servlet.FlowController">
	    <property name="flowExecutor" ref="flowExecutor" />
	    <property name="flowUrlHandler">
			<bean id="webFlowUrlHandler" class="org.springframework.webflow.context.servlet.WebFlow1FlowUrlHandler"/>
	    </property>
	</bean>
	
	

	
	<webflow:flow-executor id="flowExecutor" flow-registry="flowRegistry"/>

	<webflow:flow-builder-services id="flowBuilderServices" view-factory-creator="mvcViewFactoryCreator" />
	
	<bean id="mvcViewFactoryCreator" class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">
		<property name="viewResolvers">
			<list>
				<ref bean="viewResolver"/> 
			</list>
		</property>
	</bean>	
		
</beans>

Thanks
