getConnection

protected Connection getConnection()
                            throws SQLException

Gets a connection from the datasource, retrying as needed. This was implemented because in some minimal configurations (i.e. little logging and few services) the database wasn't ready when we tried to get a connection. We, therefore, implement a retry loop wich is controled by the ConnectionRetryAttempts attribute. Submitted by terry@amicas.com
