In part 5 of this article we showed a way to stop a Liferay server using Apache Ant. Today we will look into starting a server. A person might say that you just run the start script and you are done. More is needed to verify that the server starts correctly. Furthermore if we need to perform actions after a successful startup we need to delay until the startup is complete. All the tasks we need to accomplish this have already been discussed. So we will start with the whole script and touch on the various areas

Very similar to our previous examples we execute the startup script, wait for the log files to appear and monitor the log files. Once the correct messages appear in the log file appear we have a successful startup. Keep in mind that multiple starts and stops being recorded in the log file will give you false positive results with the log files. You will need to move or truncate the existing log file. This concludes this series of articles.
