在给客户安装完sql server2005后，配置好环境变量，启动tomcat后报错"org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Network error IOException: Connection refused: connect)",仔细检查数据库连接类和连接池配置，没有发现不对的地方，后来打开SQL SERVER数据库配置工具，一看，原来SQL Server 2005 网络配置中的TCP/IP默认为禁用，改为启用即可！但是sqlserver服务必须重启方可生效！
