import org.apache.struts.action.*;

public class LeaveAction extends Action{
    
    public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response)throws Exception{
        HttpSession session=request.getSession();
        session.invalidate();
        return mapping.findForward(null);
