Overview

WildFly class loading relies on modules that have to define explicit dependencies on other modules. This model is different from the previous EAP 5 hierarchical class loading model.

WildFly adds module dependencies for a JEE deployment in a very specific order, starting from the highest priority to the lowest priority:

1. System Dependencies - these are the dependencies that are automatically added by the container. For more details see automatic dependencies
