Have tried putting the JDBC driver in $JBOSS_HOME/server/<server config>/lib, that is where the I always put jdbc drivers (The default Hypersonic driver is also in this directory).
Hi, i've just upgraded from posgreSQL 8.1 to 8.2.3. I placed postgresql-8.2-504.jdbc4 in /deploy/ejb3.deployer, restarted jboss and the proces breaks when it gets to detecting what postgresql driver is being used! I remove the jdbc4 driver and replace it with, my original driver, postgresql-8.1-405.jdbc3 and all works fine again!
