</html>小弟是初学stuts，想问问 怎么提交datagrid数据到 数据库中，提个思路，有源码和例子最好了，还有怎么从数据库中数据用 logic：present和logic：iterate把数据显示出来啊，谢谢各位了
1 <form action="x.do?method=你的struts里的action里面的方法名字但是不包括括号" method="post"> method是你的struts-config.xml里面配置的参数 parameters="method" 配置在<action-mapping>里面
2 request.setAttribute("list",list);
<logic:present name="list">//当前请求是否存在名字叫做list的集合
<logic:Iterater name="list" Collection="${requestScope.list}">//迭代标签
${list.封装数据的javaBean的参数名字}
</logic:iterater>
</logic:present>
