Simple CGI programming

A simple HTTP server serves static HTML, Javascript, CSS, Images, etc. Sometimes you need a bit of dynamic content from the server-side. There are simple microframeworks to mega frameworks to achieve this. You could use any of these available web frameworks on the server side.

JBang and My Own Custom Catalog

JBang, once installed, allows you to run any java file like a script. Superbly helpful if you want to hack something quickly. It can also install the same as app or binary so it can be found on your PATH. So you can forget about jbang and just run the app.
