According to build.xml the action and the model source directories both get compiled into the same jar directory. So we're wondering: Is their separation just for clarity? Don't see a difference in the build.xml ant way of exploding or deploying. Don't see a difference in the Eclipse way either. Is there a difference they are treated anywhere? Context: Switching project from Seam 1.2.1 to Seam 2. Looking at seam-gen, making example application, works greats. Noticing model and action directories. Works fine. Very nice to update actions almost immediately with explode. Thanks! Understand (almost obviously) model doesn't allow immediate updating when exploding.
