Oracle package invalidate problem with the jdbcOracleConnectionCacheImpl ()

Question

Hi all,
I am using the OracleConnectionCacheImpl(); to Create the Oracle connection pool (OracleConnectionCacheImpl class)
In my application i am calling the oracle stored procs.
(DB environment :Oracle 9i)
to call those stored proc i used the Prepared statements.
All the requests are calling the same java bean to invoke the same package.
when ever the changes occured in the db level,(it means if that package is invalid. i.e when ever the db refreshes occured), all the requests are geting oracle error.
after the oracle package become valid.. still i am geting the oracle errors.
it should not happen, because stored proc is in valid state.
if we restart our adapter or java service then we are geting the proper responses.
we don't know when the db problems occurs, when it will be solve
can any one help me to make my application stable
kindly help me to get underastand the behaviour of our java code and the jdbc behaviour.
if any one didn't understand the above description i can mail you the code what i am using..
Thanks in advance
