Maybe you should use jdbc:mariadb://
instead of jdbc:mysql:// ?? According to this page, https://mariadb.com/kb/en/about-mariadb-connector-j/ , jdbc:mysql scheme compatibility MariaDB Connector/J 3.0 only accepts jdbc:mariadb: as the protocol in connection strings by default. When both MariaDB Connector/J and the MySQL drivers are found in the class-path, using jdbc:mariadb: as the protocol helps to ensure that Java chooses MariaDB Connector/J. Connector/J still allows jdbc:mysql: as the protocol in connection strings when the permitMysqlScheme option is set. For example: jdbc:mysql://HOST/DATABASE?permitMysqlScheme (2.x version did permit connection URLs beginning with both jdbc:mariadb and jdbc:mysql) HTH Regards Lorenzo Da: Viktor Nikolov <[email protected]> Inviato: lunedì 4 settembre 2023 19:32 A: [email protected] Oggetto: "No suitable driver found for jdbc:mysql" after upgrade to 1.5.3 Hi! My Guacamole installation stopped working after the upgrade from 1.4.0 to 1.5.3. :-( I'm getting the "No suitable driver found for jdbc:mysql" when the Guacamole starts. Please see attached catalina.out (logging level: debug). I'm using native installation on Ubuntu 22.04.3 running Tomcat 9.0.58 with MariaDB 10.6 authentication and I believe I did everything according to the manual. I compiled and installed guacd from sources. I downloaded guacamole-1.5.3.war and copied it to /var/lib/tomcat9/webapps/guacamole.war . I downloaded guacamole-auth-jdbc-1.5.3.tar.gz, extracted it and copied guacamole-auth-jdbc-mysql-1.5.3.jar to /etc/guacamole/extensions . I deleted the jar with previous version. I downloaded recommended MariaDB Connector/J 3.2, mariadb-java-client-3.2.0.jar, and copied it to /etc/guacamole/lib . I deleted the jar with previous version. I rebooted the system. I didn't make any changes to guacamole.properties. It worked fine with 1.4.0. Parameter mysql-driver is set to mariadb (see the attachment). What am I missing??? Viktor
