Pooled Connection

[LBS]

Hi hope someone can solve this one,

I'm using a JNDI datasource to create pooled connections to a 9i DB.
In my Java code I'm using an OracleConnectionCacheImpl to attache to
this.
My problem is that I want to open X number of connections to the
database with on startup, but when I connect from withing java using
the Connection object specify a user name and password, to perform the
query with.
When I try this I get the following error message:
User credentials doesn't match the existing ones

Thanks
