自己写的基于JSP+servlet+Javabean的bookshop源代码

<jsp:useBean id="cart" scope="session" 
             class="beans.CartBean"/>

<%
    String strBookId=request.getParameter("id");
    if(null==strBookId || "".equals(strBookId))
    {
        response.sendRedirect("index.jsp");
        return;
    }
    else
    {
        cart.deleteItem(Integer.valueOf(strBookId));
        response.sendRedirect("showcart.jsp");
    }
%>
