public class DCSAction extends org.apache.struts.action.Action
Base Action class that sets up access to global structures as instance variables. NOTE: using instance variables this way in an Action is dangerous. We have to at least make sure we don't use any session-specific variables this way, since the Action class is shared by all threads, and the session-specific vars may be re-assigned by another thread.
