HTTP ERROR 404

Problem accessing /manuais/http/HTTP.html. Reason:

    There is no Action mapped for namespace /manuais/http and action name HTTP. Check if there is such an action name with such namespace defined in the xwork.xml and also if such an action class exists. Check also the log to see if the action class is successfully loaded.

Caused by:

Check if there is such an action name with such namespace defined in the xwork.xml and also if such an action class exists. Check also the log to see if the action class is successfully loaded.
