Archers, crossbows are able to wreck havoc from behind your main line. Javelins have to be in front of your main line first and when the enemy infantry is committed, sweep them around the line and let them throw their things into the back of the enemy. Javelins works the best when they don't have friendly units between them and the enemy.
To be honest, I don't like javelins. I use them if I don't have anything else (like Rome, they have to start with them until they can have the crossbows). I rather like to use slingers (the Funditori, Briton slingers), Egyptian/Persian archers, crossbows. These are also very handy to lure the enemy out of their forts if you don't have onagers because they outrange the fortress towers. They also do quite some damage to defenders on the wall if you happen to attack a walled settlement (but this can be avoided by luring them out by sieging or attacking a reinforcement force in the area)
