Publicado por Miguel Angel Martin (1 intervención) el 11/11/2008 23:31:43
Hola estoy montando un ejemplo de struts, me gustaría saber si alguien me puede ayudar con este problema,ya que por más vueltas que le doy no consigo ver el error, el problema me surge al pulsar el botón submit del formulario de ejemplo:
Error Otenido:
type Status report
message No action instance for path /loginUsuario could be created
description The server encountered an internal error (No action instance for path /loginUsuario could be created) that prevented it from fulfilling this request.
