It just occurred to me why this is broken. Two copies of the Tomahawk library in both the WAR and the EAR because they both have a dependency. When the schedule component in the web application checks the class type for the parameter, the classes fail to match because they come from two different libraries. (Or at least something close to this.) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3970777#...
