Struts 2 : Warning :No configuration found for the specified action: 'Login.action' in namespace: '/'

By -
No configuration found for the specified action: 'Login.action' in namespace: '/'''. Form action defaulting to 'action' attribute's literal value. Solution: To remove this warning you need to change following... See your struts.xml file what name you have specified... If you are using namespace / and your action name is 'Login' then  replace Login.action to Login as given below... <s:form action=" Login.action " method="post" >   Use below with namespace  1) <s:form action=" Login " method="post" namespace="/">   Or   2) <s:form action=" /Login " method="post" >   Now you will not get this warning.
