How would I find out which Invoker I used? I took the default that came with JBoss 4.0.5GA. My EJBs does not declare any Invoker and so do my ejb config files. I searched JBoss's output and found the following: anonymous wrote : | 12:54:19,531 INFO [SocketServerInvoker] Invoker started for locator: InvokerLocator [socket://192.168.1.101:3873/] | 12:54:45,562 INFO [TomcatDeployer] deploy, ctxPath=/invoker, warUrl=.../deploy/http-invoker.sar/invoker.war/ | 12:55:07,625 WARN [BisocketClientInvoker] Unable to send ping: shutting down PingTimerTask Do those mean anything to you?
