Our Corda Enterprise server will be run as a Linux service as described in the Corda documentation. Is it possible to drop a new CorDapp jar file into the cordapp directory and have it recognized by the server, or do you have stop the node server first in order to deploy the CorDapp? As a related question, could you hot deploy (replace) an existing CorDapp on a running Corda Enterprise server node, or do you have to stop the node service first?
