我用了oracle8.15的驱动classes111.zip,heoracle8.17的classes12.zip都出現如下错誤，经檢验是conn = ds.getConnection()時抛出异常：
org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFact
ory, cause:
java.sql.SQLException: Io 异常: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=168
821248)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))

       at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:323)
