解决方案
解决方案二：
SqlServer2000要打补丁
解决方案三：
引用楼主mycatok的回复:
java.sql.SQLException:[Microsoft][SQLServer2000DriverforJDBC]Errorestablishingsocket.
主要是这个错，后面那个是这个引起的。就是连不到SQLServer2000数据库，请检查请cmd进命令行环境，输入netstat-a-n或者是netstat-an，在结果列表里看是否有类似tcp127.0.0.1(或空、或localhost)1433listening的项。如果没有，你需要确保这几件事情：1.SQLServer服务要启动2.需要给sqlserver2000打上至少sp3的补丁3.防火墙不要阻止1433端口，或干脆关掉防火墙，包括xp自己的windows防火墙4.配SQLServer使用TCP/IP协议和1433端口
