Can ControlTier scan for exception messages in my app server log?
Application servers (i.e., servlet containers, J2EE servers) are notorious for creating the scenario where the server itself starts up fine but the webapp or EJBs that they load and run begin to spew exception messages during their startup. These exception messages might be caused by ports that are not listening, database misconfigurations, etc. ControlTier provides an Ant task called FileMonitor which should be used in a Start workflow sequence that scans the log file for success and failure criteria. This FileMonitor runs in its own thread and reads the log file for pre-configured regular expressions. When a success or failure point is reached, the configured action is then dispatched. We often also use the WaitFor task in this process.
