public class MailreaderSupport
extends com.opensymphony.xwork2.ActionSupport
implements SessionAware, ApplicationAware

Base Action for MailreaderSupport application.

Note that this class does NOT implement model driven because of the way the pre-existing model is designed. The MailReader DAO includes immutable fields that can only be set on construction, and some objects do not have a default construction. One approach would be to mirror all the DAO properties on the Actions. As an alternative, this implementations uses the DAO properties where possible, and uses local Action properties only as needed. To create new objects, a blank temporary object is constructed, and the page uses a mix of local Action properties and DAO properties. When the new object is to be saved, the local Action properties are used to create the object using the DAO factory methods, the input values are copied from the temporary object, and the new object is saved. It's kludge, but it avoids creating unnecessary local properties. Pick your poison.
