Hi: I am on the point of implementing lock and unlock method. My question is how most people store cookies with record. I have two ways to do it. 1. I have a object class called Contractor. This object store the information about one record. So I can add a property called cookie to adhere this object. So when someone locks this record, he updates this property and unlock this record by updating this property to 0.
2. Using a Map collection to store cookie, like <Key: recNo, Value: cookie> If record is unlocked, it sets value as null or 0.
Can someone give me suggestion that which one is better? I worry about the synchronize problem.
