    - by Kyle Partridge
    Is it possible to have a static collection as a member of a hibernate entity? Say I have an object Question: public class Question { private String category; ... } Would it be possible to populate a static Set<String> that is a distinct set of all categories in the Database?

    - by Zubair
    For example, to denote a String I could use: {string,"hjggjhhggJ"} and a list would be: {list, [1,2,3]} : I guess I have found that I am running into situations where I need types, for example to distinguish between strings and lists and I am not sure how to proceed.

I'd like to use the java.sql.PreparedStatement to create my statements so that i don't have to validate every string etc. with my own methods. Is there a way to use the PreparedStatement without the calling java.sql.Connection.prepareStatement(String) function, because I don't have a java.sql.Connection?
