You will have to specify the port of 8080....you can't send and receive a message on the same port at the same time. So you have to use what one of my old bosses called the "backdoor port". 
Since your request will be going out from the hub on 80 you can't receive it on 80 as well. They'll crash. So, just use:
http://hub-ip:8080/hub/zwaveRepair
BTW...i didn't even know that was possible. Good call @aaiyar.
