This is nothing JSF-special. Just Google for "ImageServlet".

1st hit is not the only one hit =) Just check 50 hits or so.

"imageservlet.java" might be a better keyword though.

But in fact it's simple:

1) store images as BLOB in DB

2) create a servlet which listens on, for example, /image

3) call it with for example h:graphicImage src="/image?id=1", /image/1, /image/blah, etc.

4) in this servlet get the BLOB as Inputstream and write it to the outputstream of the response.

Do a more specific Google search. Search on "imageservlet site:sun.com" (without the quotes btw).

Create the file using FileInputStream. Inject ur bytesreatm that u got from blob object to this streatm and name the file as .jpg (the original file name i mean). The file name shoulf be passed to src entry..regardsShanu
