hi all,
i m facing a little problem with ejb3.0..

I have an EntityBean which is in CMR with an Item enityt bean (an expense is made of multiple items)

public class Expense {

.....

public void setItems(Collection items) {
..
}


public Collection getItems() {
..
}
}


Now, i would like to write a method (getTotalAmount()) that does the sum of all the Items in an expense and return the total., andp ut this method ont he EntityBean (rather than on a Session)

if i do that, jboss complians that no setter method has been defined for the totalAmount property

am i putting the getTotalAmount method in the wrong bean? shall i put it ont he SessionBean instead?

anyone could help?

thanks and regards
marco
