There is no Action mapped for namespace [/] and action name [login.action] associated with context path [/chaining].

Answer 1

Remove the suffix from your chained Action name, from this

<result name="success" type="chain">login.action</result>  

to this

<result name="success" type="chain">login</result>  

Note that Action Chaining is not recommended, Redirect Action or some other ways should be preferred.

From the official documentation:

Don't Try This at Home
As a rule, Action Chaining is not recommended. First explore other options, such as the Redirect After Post technique.
