Jenn,
You may have to invest in some feliway to help calm JJ down a bit. It may work... or not, but could be worth a try if he continues to be so aggressive.
When I first brought my Magic home and put him out on a tie out rope he got to meet MIL's very large German Shepard. The first thing he did was walk her up the walk and more or less draw a line on where she could go.
Anytime she started to come down the walk he would run up along side her and walk her back to MIL's house.
The dog used to do a bark and a false start at all the other cats just to watch them jump I think, but she never challenged Magic.
