<%@ page import= "java.sql.*"%>
<jsp:useBean id="dbBean" scope ="session" class = "test.db.conn" />
<%
	dbBean.connection();
	Connection conn = dbBean.con;
	Statement stmt = conn.createStatement();
	String sql;
	ResultSet rs;
	ResultSet rs1;
	ResultSet rs2;
	ResultSet rs3;
	String sql1;
	String sql2;
	String sql3;
	%>

答案：<jsp:useBean id="dbBean" scope ="session" class = "test.db.conn" />
楼主,个人感觉,你的class只是指向了一个包而已,缺少类名吧.难道你定义的类教conn吗,你为什么不大写第一个字母呢,不过这个不重要.楼主的类真的是conn吗,还是conn只是一个包.

其他：jsp的错误报告没什么用。
尝试Debug一下，看是哪一步出了问题 
扣扣：271047329 看一下你  test.db.conn 这个类 你没有导入相应的包文件，提示空指针错误 

上一个：jsp 按钮中写代码吧text.value中的数据存入到yidong(库名)mian(表名)中
下一个：一个网站论坛用PHP的，其它的用JSP的，想问下对以后租服务器有关系吗？必须租两个吗？
