Creating Dynamic images on the fly in spring?

[multiplexor]

Hey all,

Hope everyones doing well :-)

I've been reading of a package that can create charts... However!
How could i go about creating a very basic image... ?

Basically i need a random numbered image (security) for my site, however i'm not sure how to go about starting it in the spring environment...

I'd like to have it where I specify some type of hash value that the controller could use to create the image... Then just compare the entered value with the hashed value.. when the page has been submitted...

Thus 1 <input> field and one <img src="dynamicImageCreation.do?hash=AF234FERB4">

Anyone have examples on how to do this or any idea how it could be done via spring?

Thanks all :-)
