我系统windows2003+tomcat+jdk这些运行都没有问题作JSP页面什么的。装上sql server 2000打sp3补丁下载jdbc for sql server 2000+sp3补丁装上后，CLASSPATH也配了。。用代码测试
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="err.jsp" %>
<%@ page import="java.util.*"%>
<%
public class Connect{
private java.sql.Connection con = null;
private final String url = "jdbc:microsoft:sqlserver://";
private final String serverName= "localhost";
private final String portNumber = "1433";
private final String databaseName= "university";
private final String userName = "admin";
private final String password = "*****";
// Informs the driver to use server a side-cursor,
// which permits more than one active statement
// on a connection.
private final String selectMethod = "cursor";

// Constructor
public Connect(){}

private String getConnectionUrl(){
return url+serverName+":"+portNumber+";databaseName="+databaseName+";selectMethod="+selectMethod+";";
}

private java.sql.Connection getConnection(){
try{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
con = java.sql.DriverManager.getConnection(getConnectionUrl(),userName,password);
if(con!=null) System.out.println("Connection Successful!");
}catch(Exception e){
e.printStackTrace();
System.out.println("Error Trace in getConnection() : " + e.getMessage());
}
return con;
}

/*
Display the driver properties, database details
*/

public void displayDbProperties(){
java.sql.DatabaseMetaData dm = null;
java.sql.ResultSet rs = null;
try{
con= this.getConnection();
if(con!=null){
dm = con.getMetaData();
System.out.println("Driver Information");
System.out.println("\tDriver Name: "+ dm.getDriverName());
System.out.println("\tDriver Version: "+ dm.getDriverVersion ());
System.out.println("\nDatabase Information ");
System.out.println("\tDatabase Name: "+ dm.getDatabaseProductName());
System.out.println("\tDatabase Version: "+ dm.getDatabaseProductVersion());
System.out.println("Avalilable Catalogs ");
rs = dm.getCatalogs();
while(rs.next()){
System.out.println("\tcatalog: "+ rs.getString(1));
}
rs.close();
rs = null;
closeConnection();
}else System.out.println("Error: No active Connection");
}catch(Exception e){
e.printStackTrace();
}
dm=null;
}

private void closeConnection(){
try{
if(con!=null)
con.close();
con=null;
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String[] args) throws Exception
{
Connect myDbTest = new Connect();
myDbTest.displayDbProperties();
}
}
%>
就提示这些东东：
type Exception report

Clearly 本身代码的问题! Why would you include a class in a JSP?
