Catching validation errors

Question

I want to put validation logic inside a setter method of an entity object. Where can I catch exceptions raised inside setter methods? I would like to have something like this:
public class MyEntityImpl extends EntityImpl
public static final int EMAIL = 0;
public void setEmail(String value) throws oracle.jbo.JboException
     boolean isValid =true;
          validation logic
if(isValid) setAttributeInternal(EMAIL, value);
else{
     throw new oracle.jbo.JboException(″An email address must be ...″);
Where do I catch oracle.jbo.JboException?
Where can I catch oracle.jbo.AttrValException: JBO-27014: Attribute ... is required ?
Is there another way to include validation?

Hi,
look at entity object wizard.
There you will find a section for validation.
You can set validation for a whole entity object or for one attribute (either set validation in declarative or in a programmatic way).
Have a look at the brilliant BC4JToyStore example by Steven Muench as well, how EO validation is handled.
Hope, that helps.
