I can't do this because I'm putting those lines in an action who was caled by another action wich fill the response in.
private ActionForward doDispatchMethod(ActionMapping mapping,
                                           ActionForm form,
                                           HttpServletRequest request,
                                           HttpServletResponse response,
                                           String methodName)
                                    throws IOException
            Method method = getMethod(methodName);
            Object[] args = { mapping, form, request, response };
            fwd = (ActionForward) method.invoke(this, args);
        if (request.getAttribute(ERROR_KEY)!=null)
             response.reset();
             response.addHeader("WSC_RESPONSE", "STRUTS_ERROR");
             System.out.println(response.containsHeader("WSC_RESPONSE"));
             response.setHeader("WSC_RESPONSE", "STRUTS_ERROR");
             System.out.println(response.containsHeader("WSC_RESPONSE"));
        else
             response.reset();
             response.addHeader("WSC_RESPONSE", "OK");
             System.out.println(response.containsHeader("WSC_RESPONSE"));
             response.setHeader("WSC_RESPONSE", "OK");
             System.out.println(response.containsHeader("WSC_RESPONSE"));
        return fwd;
    }
