Hello, Which query to write in JPQL for backing up database on disk? If in JPQL it's not available even native sql query will do.
Also, i would like to bring one issue in front of stackoverflow developers :- This site doesn't properly work in Opera (Opera 9.63). Whenever i write question and click "Post Your question" The button click event doesn't fire at all, may be, the server side event doesn't fire or something. However, no such problem comes in IE and firefox.
