[JBoss-user] using a pattern to validate field values

[Tania G. Ramos]

Hi, I was thinking about the several ways that exist to validate a field value....   I had some ideas, but I was wondering if there is a  pattern that does it...     In my entity bean, I am using the pattern VO and when I'm setting the cmp fields, I wanna make a validation of some fields but I don't want to put this validation inside this method. Ex: public void setDVO(ArrayDVO pmtDvo)    {       setName((String)pmtDvo.getFieldByName(this.ATTR_02));       setAge((Integer) pmtDvo.getFieldByName(this.ATTR_03));       setAddress((String)pmtDvo.getFieldByName(this.ATTR_04));   } In this case, I would like to validate if the age value is a correct number..... but I don't want to put this validation inside this method setDVO(). The way I was doing was:             creating the method setVldAge(Integer age) and inside this method, after validating it, I used to call the setAge.....  and in the method setDVO() I was calling the setVldAge(..) instead of calling the setAge(..)             But, I don´t think that this is the best alternative...             I think that using a pattern would be a better solution....     How do you usually validate these fields?   Thanks, Tânia Ramos Analista de Sistemas - NDS * [EMAIL PROTECTED] Fóton® Informática e Serviços ( Fone: (61) 328 5060 R.240
