将mysql-connector-java-3.1.1-alpha-bin.jar文件拷贝到 java的安装目录下的/lib目录.在CLASSPATH中增加了这个jar文件,连接无效.
快疯掉了.
我的系统是RedHat AS 3
测试页代码为:
[PHP]<html>
<head>
<title>Test JDBC For MySQL</title>
</head>
<body>
<%@ page contentType="text/html；charset=gb2312" %>
<%
Class.forName（"com.mysql.jdbc.Driver"）.newInstance（）；
java.sql.Connection conn；
conn = java.sql.DriverManager.getConnection（"jdbc:mysql://localhost/mysql?user=root&password=zxcvbn"）；
%>
</body>
</html>[/PHP]
将
[PHP]Class.forName（"com.mysql.jdbc.Driver"）.newInstance（）；
#换成
Class.forName（"org.gjt.mm.mysql.Driver"）.newInstance（）；
[/PHP]
依旧无效, "涛声依旧啊"!!!!!!!!!!!
错误提示如下 :
