jsp中代码要写<%%>

<jsp:setProperty name="rent" property="width" param="width"/>

注意param和value ?可能会出错误啊

<jsp:setProperty name="rent" property="*"/>

使用javabean要注意引进包啊

<%@ page import="bean.rent" %>

<jsp:getProperty name="rent" property="xxxxx"/>

<jsp:forward page="c.jsp"/> ?也可以进行跳转

?

oracle:

class.forName("oracle.jdbc.driver.OracleDriver")
