We can use the following method to specify a composite primary key class for an Entity class:




When an instance of CompositePK class will be created?
When it will be destroyed?
Instances of CompositePK may be pooled?

Please feel kind to answer above three questions.
 
It is sorta covered in the JavaRanch Style Guide.
