Note on Java complexity

The problem is that much of the Java stuff out there is just written by really smart morons who seem to love complexity for complexity's sake. Even in the API itself! Ever used the Calendar API? It's written by a monkey. Ever check out the code under the JSTL? Those guys have to be on crack. It's not the language itself that causes these problems, it's the culture around the language. When programmers respect patterns more than solutions, you know something is broken.

Complexity leads to disaster. Your application should be built around simple constructs and understandable layers, which combine to perform complex tasks. The code itself, however, should avoid complexity at every stage. This is much easier to say than to do, though, since many programmers are afraid of missing important pieces, or of oversimplifying.
