jsp代码如下：
<%@ page contentType="text/html;charset=gbk"%>
<%@ page import="java.sql.*"%>
<html>
<title>测试数据库</title>
<body>
<%
out.println("测试数据库");

try {
Class.forName("org.gjt.mm.mysql.Driver").newInstance();

}
catch (Exception E) {
out.println("Unable to load driver.");

}

try {
Connection C = DriverManager.getConnection("jdbc:mysql://localhost/netshop?user=mysql&password=&useUnicode=true&characterEncoding=8859_1");
Statement s=C.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
ResultSet rs=s.executeQuery("select * from shop_admin");
out.println("<table border=1>");
int i=1;
for (i=10;i<20;i++)
{
if (rs.absolute(i))
{
out.println("<tr><td>");
out.println(rs.getString(1));
out.println("</td>");
out.println("<td>");
out.print(rs.getString(2));
out.println("</td>");
out.println("<td>");
out.print(rs.getString(3));
out.println("</td></tr>");
}
else
{
break;
}

}
out.println("</table>");
rs.close();
s.close();
C.close();

}
catch (SQLException E) {
out.println("SQLException: " + E.getMessage());
out.println("SQLState: " + E.getSQLState());
out.println("VendorError: " + E.getErrorCode());
}

%>
</body>
</html>

出现的错误页面如下：测试数据库

Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.io.EOFException

和MySQL的“交流”失败，因为出现了异常** BEGIN NESTED EXCEPTION ** java.io.EOFException

这个jsp编程错误需要你把JSP的应用掌握透哦

说明在Windows下没有设置用户名和密码

		自动登录	找回密码
密码			注册
