I try to learn jsf and I like to play with image processing, so I'm trying to set up an application that shows a picture that will be processed in different ways depending on user action. I've got it working but I use Servlet#doGet().
I feel it is bad practice to mix custom-Servlet with jsf-style. (Is it really?) So how can this be done with beans only?
I have found Forcing a save as dialogue from any web browser from JSF application but I want to see the image embedded, not as a download.
