Upload it using FileUpload, get the image as an inputstream and render it as an image for preview. Or store the resulting image in the session (possibly as a RenderedImage object) and then display that.

At what point you decide to store the image is up to you.

After you upload the image you would have to store it somewhere where it is directly accessible by the web application and serve it to the client as if it were already a part of you web app or store the image in memory (to be read session), create a servlet that when called will output this image (use output stream instead of writer) and provide the neccessary header (content type), and provide the image as having the source your servlet.
