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.

Class Loading Precedence

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.
  2. User Dependencies - these are the dependencies that are added through jboss-deployment-structure.xml, through the Dependencies: manifest entry for modules or through Class-Path: for JAR files.
