I have project generated with seam gen. So I have src/model, src/action ,src/data and src/test directories. Everithing was fine, until I correctly sort my classes to model and action directories. Now I have only entities in model directory and actions, entity home objects, web service endpoints etc. in action directory. But when I run explode ant target (or deploy) I will get war directory (war file) with this structure
src/data with all of my entity seam components.

WEB-INF/classes with all of my classes from model dir
WEB-INF/dev with all of my classes from action dir
