Spring web flow: Not proceeding from first page to second page

I am writing a web flow. the first page could be displayed using the /loginForm.htm url given for the Login controller. Once I fill the login page and click on submit, it is not moving to the second page. No message is being displayed on the console. Please kindly look into it.

loginForm.jsp

webFlows.xml

customer-servlet.xml
