jsp 连接 sqlserver 问题？

atjamy 2004-11-22 12:07:00

用的是tomcat 5.0.28
sqlserver是8.00.194

test.jsp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=pubs";
//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 jobs";
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>

总是报错如下
javax.servlet.ServletException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:825)
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:758)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)

连SQL，形式如下：
<%@ page import="java.sql.*"%>
<%@ page import="java.util.*"%>
<%@ page import="java.io.*"%>
<%@ page import="com.microsoft.jdbc.sqlserver.SQLServerDriver"%>
<%@ page import="java.lang.*"%>
<%@ page contentType="text/html; charset=gb2312" %>

<%
request.setCharacterEncoding("gb2312");
String CLASSFORNAME="com.microsoft.jdbc.sqlserver.SQLServerDriver";
String SERVANDDB="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=jspdev";
String USER="bn";
String PWD="bn";
%>
===============这是个固定面，只要在其它页引用就OK
还有你出现上面的问题，
很大可能是你没有jdbc驱动，安装SQL驱方法：把MS的三个文件copy到tomcat的命令目录下的bin里面就行了。
