把jsp中的逻辑处理的部分提取出来形成servlet

Answer 3

用了啊，el表达式也有，
      <jsp:useBean id="card" class="com.bank.entity.Card" scope="session"></jsp:useBean>
          <td width="451" valign="top"><div id="div1" style="display:none">
            <table width="444" height="218" border="1" cellpadding="0" cellspacing="0" bordercolor="#FF99CC">
              <tr>
                <td width="127" align="center"><jsp:getProperty name="card" property="cardId"/></td>
                <td width="301">&nbsp;</td>
              </tr>
              <tr>
                <td align="center">货币类型</td>

技术都用到了，但是业务不同，只做参考

Answer 6

将页面中的javabean都抽取出来，放在后台用java处理，将页面间的跳转都通过后台web.xml做跳转控制。就可以了。让jsp纯粹的做展示和交互，web.xml和servlet做业务跳转控制，然后由servlet调用具体的代码去处理业务，包括和数据库打交道等等。
