Pocket J's on AA board

[gman339]

What should my line be here? I thought the initial c/r was just a bluff. I intentionally min raised to attempt to make it look like I was trying to build the pot. Obviously, it didn't scare him. After that though....and with the spade hitting....I have to get away obviously. I can't fold to the initial reraise right? Should I just smooth call there?
