问一下关于jsp连接sqlserver的问题
我是才开始自学这个的 所以问题比较菜 见谅:)
先说一下用的工具 eclipse + myeclipse + sql server 2000(sp4) + tomcat 6 + windows XP (因为是自己学,所以用的XP)
首先,tomcat是配置好的,jsp页面可以访问,jdbc也是安装了的,jar包也分别放到了tomcat/lib,%java_home%/jre/lib/ext以及项目的web-inf目录下,1433端口已经打开,问题就在于jsp连数据库。安装,建立数据库时全是默认设置。
一下是我的代码:(照书上写的)
<%@ 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=testdb ";
//pubs为你的数据库的
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 test ";
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();
%>
</body>
</html>
访问jsp页面时报错:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
