Spring Web Flow 2 Setup, not rendering ${flowExecutionUrl} nor even starting - spring-mvc

Question

I am putting together a simple Spring MVC with Web Flow app and I cannot get it to render the flowExecutionUrl on a page so that I can navigate to the next state. Which I assume means the flow isn't starting(is there an explicit trigger?).
I'm assuming there is something wrong in my setup, although the logs suggest I am registering the flow.xml file correctly.
My spring config(mvc-dispatcher-servlet.xml) is:
<beans xmlns="http://www.springframework.org/schema/beans"

And my flow.xml is:

<transition on="cancel" to="cancel"/>
</view-state>
<end-state id="success" view="flows/success"/>
<end-state id="cancel" view="flows/cancel"/>
</flow>
I can successfully navigate to the views.
And my jsp is:
<html>
<head>
<title>spring mvc web flow</title>
<link rel="stylesheet" href="<c:url value="/resources/css/demo_page.css"/>" type="text/css"></link>
<link rel="stylesheet" href="<c:url value="/resources/css/demo_table.css"/>" type="text/css"></link>
</head>
<body id="dt_example">
<div id="container">
<div>
<p class="notice">This is step 1 of the web flow</p>
<form id="step1" action="${flowExecutionUrl}" method="POST">
<button id="cancel" type="submit" name="_eventId_cancel">Cancel</button>
<button id="next" type="submit" name="_eventId_next">Next >></button>
Next
<c:out value="${flowExecutionUrl}"/>
</form>
</div>
<%# include file="/WEB-INF/view/footer.jsp" %>
</div>
</body>
</html>

Ok, got it...
To start the flow, you need to use the flow id in the url. So in my case use the url 'http://localhost:8080/SpringMVC/flow' for the flow with the id of 'flow'.
I was assuming the flow starts when you point to the view.
