请先看最后一段红色的话
运行一个JSP页面，发生如下错误(部分错误代码)：type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: /rwstar/rwstar/WebRoot/index.jsp(16,4) The value for the useBean class attribute DBConn is invalid.
上面是运行一个JSP页面是发生的错误，它的大概意思好像就是javaBean没有正确引用。以下是我的javaBean代码：package DB;
import java.sql.*;
import javax.naming.InitialContext;
import javax.sql.DataSource;
public class DBConn {
private Connection conn;
private Statement stmt;
private PreparedStatement pstmt;
private ResultSet rst;
private String str1;
private void init(){
Connection conn=null;
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn=DriverManager.getConnection("jdbc:odbc:rwstar");
}
catch(Exception e){
e.printStackTrace();
}
}
public DBConn(){ //构造函数
try{
init();
stmt=conn.createStatement();
}
catch(Exception e){
e.printStackTrace();
}
}
//执行数据库查询语句
public ResultSet executQuery(String s){
try{
if(stmt!=null){
rst=stmt.executeQuery(s);
}
}
catch(Exception e){
e.printStackTrace();
}
return rst;
}
}
以下是我的JSP页面代码：<%@ page language="java" import="java.util.*,java.sql.*" pageEncoding="gb2312"%>
<%@ page import="DB.DBConn" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>电子科技大学</title>
<link rel="stylesheet" href="CSS/main.css" type="text/css" media="screen,projection"/>
<link rel="stylesheet" href="CSS/default.css" type="text/css" media="screen,projection"/>
</head>
<body>
This is my JSP page. <br>
<jsp:useBean id="test" class="DBConn" scope="page" >
（就是这一行出错的） </jsp:useBean>
<%
ResultSet rs=test.executQuery("SELECT name FROM stu");
%>
<p>从STU中取值：<%=rs.getString("name") %>
</body>
</html>
希望懂javaBean的GG帮我看看，到底是哪出问题了。
刚才仔细调试了下，发觉是这句话有问题：<%@ page import="DB.DBConn" %>
想问下有javaBean经验的GG，怎么判断正确设置引入的包的路径？
我用的编写工具是MyEclipce5，用的WEB服务器是TOMCAT5。[ 此帖被clylove在2007-11-21 23:10重新编辑 ]
