I have jsp page that displays the entries of a database. I also have a method that scans this database and which deletes the entries that have "expired". This is based on manipulating dates. I want this method to be called every X seconds in the jsp page using JSTL, so that the entries that have expired are no longer displayed. How would I accomplish this?
Once your JSP is loaded on browser, you can not invoke java code. So there is no point of having any logic to call method every x seconds through jsp.
However, You can -
refresh your jsp every x seconds
make an ajax call to fetch latest data from DB and display it using javascript/jquery
