本人是oracle初学者，用jsp连接时出现ORA-01017: invalid username/password; logon denied错误
我用的是myeclipse+tomcat
代码如下
<%@ page contentType="text/html; charset=GB2312" %>
<%@ page import="java.sql.*" %>
<html>
<head>
<title>使用JDBC直接访问数据库</title>
</head>
<body>
<center>
<font size="5" color="blue"> 使用JDBC直接访问数据库</font>
</center>
<br/>
<br/>
<br/>
<table border="1" align="center">
<tr>
<td>卡号</td>
<td>姓名</td>
<td>班级</td>
</tr>
<%
Class.forName("oracle.jdbc.driver.OracleDriver");
String url="jbdc:oracle:thin:@localhost:1521:LKW";//LKW是全局数据库名称
String user="lkw"; //用户lkw是系统管理员
String password="9371719"; //这个是密码，这个密码是正确的
Connection con = DriverManager.getConnection(url,user,password);
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from card");
while(rs.next()){
%>
<tr>
<td><%=rs.getInt(1) %></td>
<td><%=rs.getString(2) %></td>
<td><%=rs.getString(3) %></td>
</tr>
<%
}
rs.close();
con.close();
%>
</table>
</body>
</html>

[解决办法]
Class.forName("oracle.jdbc.driver.OracleDriver"); 需要修改下面的样子
----------------------------
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
