You want to create a server and you're surprised you have to install and maintain server software?
The "concept or vision" that you're running up against is the idea that if you're running a server, you really should use something solid and mature that can be monitored with standard tools, instead of just running some code and starting to roll your own admin tools as soon as you want to do anything more with it.
Besides, it's not as if setting up Tomcat (let alone Jetty) were all that complex. You don't have to understand all its capabilities to use it for a simple project like this.
