if u have overridden validate method in the actionForm then ActionServlet
automatically take u to the mapping.getInput() ( i.e ur input jsp file )
where u can show the errors using <html:errors> tag . Basicallly
ActionErrors are kept in the request scope which are retrieved in the
<html:errors> tag
Else if u want to do validation even in ur action class , then create a
instance of ActionErrors in the action class and add errors to it . save the
errors using saveErrors(request , actionErrros) method available in the
Struts- Action class . So errors will be kept in the request scope and again
use same <html:errors> tag to display them
For both editUser and save saveUser use same actionForm
