The way it worked for me was: 1.- You have to extend ActionSupport because it contains the fieldErrors, actionErrors attributes and the validation logic. 2.- I use <s:fielderror><s:param>dniParticipante</s:param></s:fielderror> 3.- You must have de validation and workflow interceptors configured 4.- You must have an "input" result because in case of a validation error the workflow interceptor will ALWAYS return the "input" result. 5.- If you want javascript validation you must use <s:form ... validate="true"/>
