Is it a must to define Primary Key class for every entity bean, can I not have the same as
String, if so means how can i specify in jetace tool that this field is the primary key field, no option is there in the tool. if I am able to do the same thro' string means how can i define the query for find by primary key, is I have to define any FindByHelper class.
Is it possible to define a find method that returns a Collection object instead of Enumeration.
