Is it worth learning old technologies?

Question

Java

I studied java se and further I want to study jdbc, hibernate and spring. Should I learn servlets, jsp and other old technologies before that? A bunch of configurations via xml is especially scary :) annotations look much friendlier for a beginner.

Answer 1

Servlets are not old technology. The latest version is just over a year old.

Answer 2

A lot of configurations through xml are especially scary

This is because you yourself did not write configurations))). XML/JSON, sometimes ini. There is essentially nothing else.

Answer 3

Spring MVC is actually a front controller architecture and dispatchServlet inside
