MSSQL 2000驱动包在entity/lib目录下也存在，有点纳闷了，为什么会出现这样的异常呢！在网上搜了一下，没有发现这个问题的解决方法。后来经过查看MSSQL 2000驱动包mssqlserver.jar发现，SQLServerDriver类的包路径为com.microsoft.jdbc.sqlserver.SQLServerDriver，与entityengine.xml中默认配置com.microsoft.sqlserver.jdbc.SQLServerDriver的包路径不一直，原来是这个问题。将entityengine.xml的配置修改为com.microsoft.jdbc.sqlserver.SQLServerDriver，重新启动，OK!
