[求助]JSP连接SQL Server 2000问题，看了很多资料还未解决，求救！

06-03-24 langfanyun11

本机环境：WinXP +SP2 JDK1.5.0 Tomcat5.0.16 SQL Server 2000(XP下能用的那种版本)

已装了SQL Server 2000 Driver for JDBC Service Pack 3，并且已经把msbase.jar,mssqlserver.jar,msutil.jar拷贝到Tomcat目录下common\lib目录下，之后，修改环境变量中的CLASSPATH，
把SQL Server 2000 For JDBC 驱动程序安装目录下的
C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;
C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar;
C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar;
追加到CLASSPATH中去。

JDK和Tomcat 测试后都能正常运行，JavaBean,Servlet都测试能正常运行。

用于测试连接数据库的代码如下：
<%-- 使用JDBC驱动直接访问SQLServer2000数据库. --%>

<%@ page contentType = "text/html; charset = gb2312" language = "java" import = "java.sql.*" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd" >

<html>
<head>
<title>
use JDBC to connect SQL Server
</title>

<style type = "text/css">

</style>
</head>

<body>
<div align = "center" ><span class = "style1" > JDBC access SQL Server directly </span><BR></div>
<hr><br>
<table border = 2 bordercolor = "FF0000" align = "center">
<tr>
<td> au_id </td>
<td> au_lname </td>
<td> au_fname </td>
<td> phone </td>
<td> address </td>
<td> city </td>
<td> state </td>
<td> zip </td>
<td> contract </td>
<tr>

<%
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" ).newInstance();
String url = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName = pubs";
String user = "yc";
String password = "123";
Connection conn = DriverManager.getConnection( url, user, password );
Statement stmt = conn.createStatement( ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE );
String sql = "SELECT TOP 10 * FROM authors";
ResultSet rs = stmt.executeQuery( sql );

while( rs.next() ){
%>

<tr>
<td><%= rs.getString( "au_id" ) %></td>
<td><%= rs.getString( "au_lname" ) %></td>
<td><%= rs.getString( "au_fname" ) %></td>
<td><%= rs.getString( "phone" ) %></td>
<td><%= rs.getString( "address" ) %></td>
<td><%= rs.getString( "city" ) %></td>
<td><%= rs.getString( "state" ) %></td>
<td><%= rs.getString( "zip" ) %></td>
<td><%= rs.getString( "contract" ) %>
</tr>

<%}%>
<%
out.print( "Congratulations, The access is successful!" );
rs.close();
stmt.close();
conn.close();
%>
</table>
</body>
</html>
(该程序在其他机器上运行后能连上数据库)

JSP页面提示错误信息为：
HTTP Status 500 -

我也遇到这样的问题，实在没有办法，就用JDBC-OBDC吧！

好像是你数据库的问题,重新换一台可以使用的数据库的机器

这个问题我遇到过！！！

经过反复尝试，得出如下结论：
由于XP、WIN2000 Pro等WINDOWS版本只能安装SQLSERVER个人版或企业测试版，而连接池是无法在这些SQLSERVER版本上使用的。

同样的程序，我换到WIN2000 Server、SQLSERVER2000企业版上一点问题都没有。即便是WIN2000 Server、SQLSERVER2000标准版这样的环境也是不行的。

只有SQLSERVER2000企业版才能配置成功。

我用的是WIN2000+TOMCAT不起5.0.28+JDK1.4.2 +SQL SERVER2000标准版,用的也是SQL Server 2000 Driver for JDBC Service Pack 3,也可以连上
