See this article for some pointers about uploading files in JSF: [http://balusc.blogspot.com/2008/02/uploading-files-with-jsf.html].
And again to show stored jpeg in database to a jsf page.Better use an independent Servlet for this. Obtain the InputStream from the database using e.g. ResultSet#getBinaryStream() and write it to the OutputStream of the HttpServletResponse after having set the headers accordingly. Then call that Servlet in a JSF <h:graphicImage /> tag or just a plain vanilla HTML <img> tag.
