我昨天与你们联系过。
   我电脑系统为win7_32；安装eclipse-jee-indigo-SR1-win32；无论是从资源管理器导入，还是采用新建项目的方法，都无法启动该实例程序。一旦启动程序“酒店管理系统”实例，在控制台会排列以下错误信息：

  在安装SQLServer2005过程中，身份认证、用户、密码设置为：win和SQL Server认证，sa，空密码。
  在eclipse的该项目下，已经配制导入了SQLSverver2000的3个jar文件（msbase.jar、mssqlserver.jar、msutil.jar）。
  在SQLServer2005数据库里，已经附加了该项目的数据库db_DrinkeryManage。数据库运行也正常。
  不知什么原因，请赐教。
