It looks like maybe you used an older version of the MySQL JAR with the newer Guacamole WAR file. Are you downloading/installing all of this from the Guacamole web page, or have you custom built any of it? If you're building from the git repo, I'd suggest removing all of your WAR and JAR files, doing a clean build, and installing everything from the clean build.
