        java.lang.NoClassDefFoundError: javax/servlet/ServletContextListener

Possible fixes

The guacamole upstream image uses tomcat 8 per https://hub.docker.com/layers/guacamole/guacamole/latest/images/sha256-b1e04f8d133044992c489550ac95c16ffef2be924330a33667b136411a3ae8c4?context=explore

According to https://stackoverflow.com/a/66712199 the error above is due to using tomcat 10 instead of an older tomcat.
