请问jsp连接数据库时总是报错,大家帮帮忙吧!先谢谢啦!
连接池配置了,但是测试通不过,我的测试文件如下:
<%@ page contentType= "text/html;charset=gb2312 "%>
<%@ page import= "java.sql.* "%>
<html>
<body>
<%
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=nndrm ";
//pubs为你的数据库的
String user= "sa "; //用户名
String password= "sa "; //密码
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select top 1 * from programdata ";
ResultSet rs=stmt.executeQuery(sql);
if(rs.next()) out.print( "数据库操作成功，恭喜你 ");
rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
然后出现的错误为下:
