Description copied from class: SessionIdGenerator

this method is to access the database to generate a new session prefix on every call and also store it into the database, so that it is guaranteed that no other call ever re-uses this prefix again. Note that this method must not manage the transaction, as this method is called by initNewSession(), which begins and commits its own transaction; i.e. this method can be savely assumed to run within a synchronized transaction.

Specified by:

generateSessionPrefix in class SessionIdGenerator

Returns:

a new unique session-ID from the database to be used as a prefix for this session

Throws:

DatabaseException
