weblogic5.1中配sqlServer连接池的问题

[jediplane]

我是这样配连接池的：copy 两个包分别在classes\weblogic\jdbc和D:\weblogic\classes\weblogic\jdbcbase下，但每次启动都会抛出如下异常：
weblogic.common.ResourceException: weblogic.common.ResourceException:
Could not create pool connection. The DBMS driver exception was:
java.sql.SQLException: java.sql.SQLException: weblogic.common.LicenseKeyNotFound

不知是何缘故，我配oracle就没有遇到license的问题，哪位大侠给我一个答复？？
