Yes, it’s important to note that a web server you start runs as a totally different Java process with its own classpath and the lib folder in the CommandBox installation for the CLI has nothing to do with the libs loaded into your server. libdirs is the correct way to load up extra jars into the JVM for a server. It’s the equivalent of Tomcat’s lib folder. In many cases though you can just use this.javaSettings in your Application.cfc FWIW.
