The BaseDataSource class cannot be made Serializable because one of its
subclasses (PoolingDataSource) cannot be serialized. The
PoolingDataSource class has member variables which can contain active
database connections which can't be persisted.

Simply marking the fields with a weaker access level won't magically
persist them. This requires manually using writeObject and
readObject. This problem also occurs in SimpleDataSource. I've
attached the patch I've applied to the gborg cvs repository.
Thanks for the report.
