Um, no.
JDAM's work exceptionally well at being tossed. In 2006, an F-22 threw a 2,000 pound JDAM 24 miles. The whole point of tossing bombs is to out-range your target - i.e, air defence.
Yes, you can loiter and drop JDAM's directly near or above the target (which admittedly is their primary use in Iraq & Afghanistan), but these suckers can be tossed like crazy if they need to be (and if the aircraft is fast enough, of course).
