Hi, I have an Action and its ActionForm but when the Validate catch an Exception I put: er.add("CodInfo",new ActionError("error.ModificarApliInformacionForm.valor.required")); The value "error.ModificarApliInformacionForm.valor.required" is in com.myApp.properties.MessageResources.properties. The view(input) includes this: <html:errors /> But when an error has been produced: org.apache.jasper.JasperException: Cannot find bean informacion in any scope I tried in the JSP: <html:errors property="CodInfo" /> but its the same error I think that The hashMap ActionErrors can't be created but I don't know why. I have more Actions with ActionForms ang go OK? Any help?
