Amazing System! More configurable! Efficient code! I like the way it structured!

Hi, First of all, many many thanks for a great Open Source GPS Tracking System and continuous update for the system... Through my 10 years of programming experience. I totally agree with 100yan. The code is completely too complicated, too many complicated call, reinventing the wheel, no clear-cut MVC, too much Servlet use where JSP should be used instead and on and on... If you just want to use it, or customized based on what is available in the config file, or update the interface, it's a good choice with so many great configurable params. BUT IF YOU WANT TO ADD FEATURES, CHANGE THE CODE, IT'S A NIGHTMARE...

OpenGTS is just an amazing example of over-engineering and pathological desire for code bloat and complexity. The worst java code I have seen for ages. The OpenGTS code is like a red book for anti-patterns. Basically the whole framework (or the most important part of it ) is statically coded so that each new server (device handler) should go through the Main class initialization route. Endless chains of call delegations ( loadDevice/loadDeviceBy for e.g ), code coupling, reinventing the wheel - the DB / XML configuration layers are just a marvelous pieces of code redundancy ! Guys, there are things like O/R mapping and XML binding API coming standard in Java, use them - it will benefit the users ! Use an Inversion of Control container (Spring/PicoContainer)- it will make the code modular. Have a look at sites like codinghorror.com more often, or just take a look at java4k.com to see how complete Super Mario/ Wolf3D games with multiple levels, sprites, physics and animations are done in just under 1000 lines of java code. Less is More guys, the KISS principle !!! And yes I can understand why OpenGTS is done like that. Enterprise support :) The more complex it is - the better the chances that nobody will have a clue how to integrate new servers without the help of the authors.
