Thank's for reading my Post. I am new to hibernate.all i need some clarification and explaination.
Problem 1:
How to create seperate table for all users they sign up for my web app. i need to create 2 table's

1.User Details - Store user mail address,username,password,etc.
2.Media - Allow user to store Mp3 Files.[I have File Id[int],Mp3[LONG BLOB],Tag [Varchar]]

According to the hibernate i tried to create POJO and xml files but i done create and update for a single table. i dono how to automate the creating and updating tables. I saw somewhere in internet they use spring. If so someone explain it to me?.
