Hi!

I making a list of time-slots with a checkbox against every such time-slot in a JSP page. My requirement is that when one or more checkboxes are checked and the delete button is clicked, then the selected time slots should be deleted. The time slots are getting added in ArrayList but they are not getting removed. The code is=
