LogoutAction代碼：
public class LogoutAction extends Action{
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
// To redirect to the Login page
return mapping.findForward("success");
}
}
struts-config.xml中部分
<action path="/logout" type="com.dna.nsm.sim.action.LogoutAction" >
<forward name="success" path="/tiles/login/body.jsp" />
</action>
建議請。
