Ah ballistae, the epitome of a wasted roster slot. Immobile, easily routed, and capable of killing 40 men max.
Javelins aren't completely useless, it's just that they have a limited function and it's usually best to fill the roster slot with something else. I did find a great situation for javelins once, so I built them specifically for one battle. The AI had a stack of several royal bodyguards and not much else in one province, and I tried to come up the least painful way to assault it. So I made a stack of spears and javelins, pinned the royals with the spears, and ran the javelins behind them. Easy-peasy, then promptly disbanded the javelins...
