Given an object X; I want this object to have an image. The image must be stored in the database. I can't store the path, the actual image must be in the database.

My question can be answered by answering the following subquestions:

a). What type of field should I put in the database? (e.g VARCHAR)

b) What type of object should I use for storing and manipulating the image (at an object layer)? (e.g java.awt.Image)

c) How do I create an object of the type selected (answer of question b) from the data obtained from the database?

d) How do I save an object of the type selected (answer of question b) to the database?

e) How do I draw the image on a web page?

I am using PostgreSQL, Java and it is a web application.

Thanks!
