  1.   

    程序代码：<%@ page contentType="text/html;charset=gb2312"%>   
    <%@ page import="java.sql.*"%> 
    <%!
    public static String getGBString(String src) {
    try {
    return new String(src.getBytes("ISO-8859-1"), "gb2312");
    } catch (java.io.UnsupportedEncodingException e) {
    return null;
    }
    }
    %>
    <html>   
    <body> <%Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();   
    String url="jdbc:microsoft:sqlserver://192.168.0.1:1433;DatabaseName=jsptest"; 
    //test你的数据库的 
    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：<%=getGBString(rs.getString(1))%>   <br>
    您的第二个字段内容为：<%=getGBString(rs.getString(2))%>   <br>
    <%}%>   
    <%out.print("数据库操作成功，恭喜你");%>   <br>
    <%rs.close();   
    stmt.close();   
    conn.close();   
    %>   
    </body>   
    </html>
      

  2.   

    打SQL Server的补丁sp3就好了。
      

  3.   

    加了包后,还要加到(classpath)中去.
    要不会出现问题
      

  4.   

    OK!
    解决了
    把代码中的192.168.0.1改成localhost就可以了
    问题就这么简单，怎么没人看出来？
    谢谢大家的参与，结贴！
