1\先说说偶的配置：
   jdk-6-beta2-windows-i586；
   jakarta-tomcat-5.0.28;
    mysql-connector-java-3.1.13.tar;
   mysql-5.0.3-beta-win32-Setup;
2  classpath :
     .;C:\Program Files\Java\jre1.6.0\lib\servlet-api.jar;C:\jsp\java\lib\tools.jar;C:\jsp\java\lib\mysql-connector-java-3.1.13-bin-g.jar;C:\jsp\java\lib\dt.jar;C:\rain\Tomcat 5.0\common\lib;C:\jsp\Tomcat 5.0\common\lib\servlet-api.jar;C:\jsp\jdbc\mysql-connector-java-3.1.13-bin.jar
   ***“jsp“为偶安装目录*****
3 连接程序：
   <%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%Class.forName("com.mysql.jdbc.Driver".newInstance();
String url ="jdbc:mysql://127.0.0.1:3306/root?user=root&password=123456&useUnicode=true&characterEncoding=8859_1" ;
Connection conn= DriverManager.getConnection(url);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from logi";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为：<%=rs.getString(1)%>
您的第二个字段内容为：<%=rs.getString(2)%>
<%}%>
<%out.print("哦，god，I am success！";%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
  偶单独运行过jsp（不连接数据库的）是成功的 。
4结果是：javax.servlet.ServletException: Communications link failure due to underlying exception:
