Urgent!!! Storing and using images in Binary.

Hi all,

I am in need of an urgent requirement. My requirement is that i want to store an image in a java dictionary table and then use it in web dynpro for displaying the same.

The images need to be saved in binary in the tables. But i am unaware of how that can be done.

Can anybody please help?

Is there any standard web service in the J2EE engine that can convert a jpg image to binary? Also I need to know the way it can be retrieved in web dynpro.

Please help... Its very urgent.
