Spring web-flow with JSF ClassNotFoundException issue - maven

Question

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 https://github.com/SpringSource/spring-webflow-samples/tree/master/booking-faces. I get the following error while trying to execute a web-flow.
org/apache/myfaces/renderkit/StateCacheUtils

location=C:\Users\workspace4\.metadata\.plugins\org.eclipse.wst.server.core \tmp1\wtpwebapps\myWebApp\WEB-INF\flows\main\enterSearchCriteria.xhtml
phaseId=RENDER_RESPONSE(6)

I checked the answer from the stackoverflow post: java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener . 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

Answer 1

MyFaces repackaged StateCacheUtils in version 2.1.10. So spring-webflow will not work with myfaces 2.1.10 or higher.
I created an issue in jira for this. Maybe it will be fixed in a further version.
Meanwhile there is a very very VERY ugly workaround for this problem:
Create a class org.apache.myfaces.rederkit.StateCacheUtils in your own project and let it inherit from the new location unsing the following code:
package org.apache.myfaces.renderkit;
public class StateCacheUtils extends org.apache.myfaces.application.viewstate.StateCacheUtils {
}

Answer 2

It looks like StateCacheUtils has moved to a new package as of late last year (2012) and now lives under org.apache.myfaces.application.viewstate. It looks like a dependency issue between Spring Webflow and MyFaces. You might want to raise this on the Spring Weblflow forums.
