Re: Guacamole web application crashes when trying to use DB auth
Ahh. I turned up the verbosity on tomcat and found this in the logs: INFO: Server startup in 15700 ms Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

Re: Guacamole web application crashes when trying to use DB auth
The web application is not crashing, however any errors in your config will result in the auth process aborting, resulting in no login screen. Your logs aren't actually in your post, so please either reattempt sending those or post them elsewhere and send a link to that. I recommend checking both the Tomcat logs (which may be in journalctl) and your audit logs if your distro has SELinux. There may be additional rules you need to add to allow the Tomcat process running guac to connect to your database. - Mike On Sun, Aug 12, 2018, 12:48 doyouhas wrote: > Hello again, > > I am now dealing with some issues trying to configure database > authentication for guacamole.

Guacamole web application crashes when trying to use DB auth
Hello again, I am now dealing with some issues trying to configure database authentication for guacamole. I have successfully logged into the mysql console from the machine in question, so I know there is no networking errors running amuck. I created a skeletal properties file as follows: Once I made these changes to the properties file and restarted tomcat, I was greeted with a blank page when trying to access the web interface. Here is the relevant section from catalina[date].log My question to you fine folks is there some property I am missing which is causing the app to fail? I made sure to follow the docs to a tee after several failed attempts, I feel like I'm at the end of my java troubleshooting abilities. Any help would be greatly appreciated. -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
