Answer 1

你问题明显是不能建立数据库连接。和你jsp编译有什么关系？ 该不会你根本数据库都没打开吧？

Answer 2

由错误可以看出
root cause java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket. 无法建立数据库连接,     确定用户、密码正确，IP、端口正确
确定网络没有问题  
SQL有开着,  
把SQL打到SP4的补丁  
驱动也要对应SP4的.  ---------------------------------------------------------------  
1、下载Microsoft  SQL  Server  2000  Service  Pack  3a并安装，SQL请选用混和安装模式！！！

2、下载SQL  Server  2000  Driver  for  JDBC  Service  Pack  3

3、运行时关闭防火墙楼主试试
