How to save, retrieve and draw an image in webapplication using Java and PostgreSQL?
- by spderosso
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!
