Blank Logon screen

["Atangcho, Seth G." <Se...@jacobs.com.INVALID>]

I recently did a fresh install of Guacamole 1.0.0 on a CentOS 7 server and I was able to successfully logon the first couple of times. However, after a while, I would get a blank logon screen and get this error message in the logs:



13:23:26.728 [http-bio-8080-exec-8] ERROR o.a.g.rest.RESTExceptionMapper - Unexpected internal error:
### Error querying database.  Cause: java.sql.SQLException: Error setting driver on UnpooledDataSource. Cause: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
### The error may exist in org/apache/guacamole/auth/jdbc/user/UserMapper.xml
### The error may involve org.apache.guacamole.auth.jdbc.user.UserMapper.selectOne
### The error occurred while executing a query
### Cause: java.sql.SQLException: Error setting driver on UnpooledDataSource. Cause: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver


I have the driver in the /lib directory

> cd /usr/share/tomcat/.guacamole/lib/
 :lib -> ls
 mysql-connector-java-8.0.19 mysql-connector-java-8.0.19(1).tar.gz mysql-connector-java-8.0.19.jar

I recently installed a platform independent version of the driver from MySQL's dev website, which temporarily fixed the problem.


Need help ASAP.


Thanks,


Seth
