各位前辈 我通过MyEclipse7.0连接本机的oracle10g数据库时老是出现下面错误，帮忙解决下
Error while performing database login with the oracle。jdbc。driverOracleDriver driver：Listener refused the connection with the following error：ORA-12505，TNS：listener does not currently know of SID given in connect descriptor The Connection descriptor used by the client
was：localhost ：1521：TESTDB
驱动加载的是classes14.jar 1 楼 黑暗浪子 2010-11-04 oracle里怎么设置listener的？
