--------------------------------------------

Apache Tomcat/6.0.32


我的代码 如下：

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

String url="jdbc:sqlserver://localhost:1433;DatabaseName=shuxue";
String user="sa";
String password="";




Connection conn= DriverManager.getConnection(url,user,password);


Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);

String sql="select * from student";


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("数据库操作成功，恭喜你");%>




<%rs.close();
stmt.close();
conn.close();
%>


[解决办法]
数据库没启动吧
在cmd里打 netstat -an
[解决办法]
findstr 1433
看有没有1433端口在监听，没有就是没启动。
