\t\t\t\tUno de los primeros reclamos de los desarrolladores cuando comienzan a utilizar servicios sobre Datapower es los mensajes de error poco expl\u00edcitos y en siempre con la misma informaci\u00f3n.<\/p>\n

En general la pol\u00edtica que aplica el appliance es divulgar la menor informaci\u00f3n posible hacia el exterior, pero a nivel de administraci\u00f3n o logs la informaci\u00f3n tiene un nivel de detalle adecuado.<\/p>\n

Existe una forma muy simple de personalizar los mensajes de error en un servicio XML Firewall en Datapower para obtener respuestas m\u00e1s amigables o que cumplan un determinado formato.<\/span><\/p>\n

<\/p>\n

Lo que se debe hacer es agregar una regla de Error a la Pol\u00edtica y utilizar una plantilla para obtener el formato deseado.<\/p>\n

Paso 1: Crear una Regla de Error.<\/p>\n

Paso 1 – Click en la im\u00e1gen para maximizar<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Paso 2:<\/div>\n

Paso 3.b – Click en la im\u00e1gen para maximizar<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
De esta forma muy simple se puede lograr una respuesta mas adecuada al desarrollador o al programa que consume los servicios expuestos en Datapower.<\/div>\n
