MUTATOR You will need the mutator method obviously `public void setName( String )'
PREFERS INTERFACES Instead of using java.util.Vector, prefer to using an Java
Collection interface java.util.List.
public List getSubscriptionList()
{
List list = new ArrayList();
// fill her up
return list;
}
Pros; you change the type of ``List'' in the future. Suppose a better list appears
tomorrow
Cons: no problem
DELEGATE if you have a business object or DAO consider delegation to access.
Instead copying the accessor / mutators of the DAO to the ActionForm.
Let the DAO be a delegate because Struts supports ``nested bean properties''
out of the box,
public class CreditDetailDAO { ....
public String getAuthority() { .. .}
}
public class Employee extends ActionForm {
// Delegate it!
private CreditDetail cred;
public CreditDetailDAO getCreditDetail() { return cred; }
public void setCreditDetail( CreditDetailDAO c ){ this.cred = c };
}
Then JSP can be written like so <bean:write name="obj"
property="creditDetail.authority" />
