title: Spring web-flow with JSF ClassNotFoundException issue
body: <p>I am working on a project using Spring Webflow and JSF. I am trying to accomplish something similar to the booking-faces example of Spring Webflow <a href="https://github.com/SpringSource/spring-webflow-samples/tree/master/booking-faces" rel="nofollow noreferrer">https://github.com/SpringSource/spring-webflow-samples/tree/master/booking-faces</a>. I get the following error while trying to execute a web-flow.</p>

  <p>I checked the answer from the stackoverflow post: <a href="https://stackoverflow.com/questions/10679490/java-lang-classnotfoundexception-org-apache-myfaces-webapp-startupservletcontex">java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener</a> . However I am using Maven and don't have a /WEB-INF/lib directory. I have JSF dependencies on my classpath through Maven dependencies. Not sure, what's going on. Thanks</p>
