我今天想做个JSP连接上数据库，用的TOMCAT6.0.20+SQL SERVER 2000 开发版
已经安装了SQLServer2000 JDBC.exe和SQL2000-KB884525-SP4-x86-CHS.EXE
路径配置如下：CATALINA_BASE：D:\Program Files\Apache Software Foundation\Tomcat 6.0
CATALINA_HOME D:\Program Files\Apache Software Foundation\Tomcat 6.0
CLASSPATH .;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;D:\Program Files\JMF2.1.1e\lib\jmf.jar;D:\Program Files\JMF2.1.1e\lib\sound.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\servlet-api.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;Path C:\Program Files\PC Connectivity Solution\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;D:\Program Files\Java\jdk1.6.0_02\bin;D:\Program Files\JMF2.1.1e\bin;%CATALINA_HOME%\lib\servlet-api.jar; ;C:\Program Files\Microsoft SQL Server\80\Tools\Binn\;TOMCAT_HOME D:\Program Files\Apache Software Foundation\Tomcat 6.0
jdk可以运行，TOMCAT也可以显示页面，但是就是连接数据库出现问题
源代码如下：
<%@page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html charset=gb2312" %>
<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="123";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select job_id,job_desc from jobs";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) { %>
您的第一个字段内容为：<%=rs.getString(1)%><br>
您的第二个字段内容为：<%=rs.getString(2)%><br>
<% } %>
<% out.print("数据库操作成功，恭喜你"); %>
<% rs.close();
stmt.close();
conn.close();
%>
</body>
</html> 报错如下：

<%@ page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html charset=gb2312" %>
里面的contentType="text/html charset=gb2312"改为contentType="text/html; charset=gb2312"
中间少了个分号。
另外，import最好不要写在第一行，建议楼主改成：
<%@ page contentType="text/html; charset=gb2312" %>
<%@ page import="java.sql.* %>
看你的代码只用到了sql包里面的，所以只需要这个包。
