You can manually deploy an application (including a war file), by invoking the deploy method on the jboss.system:service=MainDeployer mbean. You can do this through the JMX Console or twiddle. (There are two deploy() methods, you can use either one but the one that takes a String is probably a little simpler. Pass it the full path name of the war file.)
Thanks, that seems to work, although why it doesn't work any longer to just drop the .war in the deploy directory is a question for another day.
Dropping a .ear in the directory works fine...
Well, its all magic anyway. Must be the phase of the moon or something
