Re: data persistence using hibernate
I've managed to make some progress with database connectivity, ended up using hikaricp instead However, I can't workout where the most appropriate place to put the connection pool close call, is there a close or shutdown function I can override so that the connection pool can be closed cleanly. I haven't had any luck in my search so far Additionally, I keep running into the following error: java.lang.IllegalStateException: Illegal access: this web application instance has been stopped already. Could not load [META-INF/services/org.mariadb.jdbc.plugin.Codec]. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access. I'm assuming this is a error more to do hikaricp so I'll enquire among their community about it, but if someone has encountered this before feel to volunteer any suggestions or recommended actions.
