Changes in DD4T 2.1 for Java

Version 2.1 of DD4T has seen many improvements and changes with respect to the DD4T 2.0.X branch. While most changes are compatible with 2.0.X, it is recommended to upgrade your web application to the 2.1.X version.

But what if you want to make your own rules for binary paths? And what if you are using the DD4T framework as well? In this post I will explain how to customize the paths to your binaries in DD4T.

Plato (~423 BC – ~347 BC) was a pretty smart guy. Among his many ideas and thoughts, his Theory of Forms had an immense influence on how we perceive and solve the philosophical Problem of universals. It basically comes down to the idea that every physical object has one or more essences (or Forms) and that if that object would not have that Form, it would not be that object: a dog is Mammal, but a giraffe is also a Mammal. What makes both animals Mammals? It’s, simply put, the Idea of the Mammal.
