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

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,
