exploded wars/sars are currently not supported (as stated in the docs).
I tried to hot deploy exploded (unpacked) war in all/farm, but I got:
arm\webapp.war (Access is denied)
at java.io.FileInputStream.open(Native Method)
Neverthless, the change seems to be picked up by the master node (the one with farm folder). But all other nodes don't get redeployed.
I am running 4.0.1-RC2 and hope to get cluster farming hot deployment working with unpacked war and ear files.
Does jboss 4.0 supports exploded hot deployment?
