No. There is extremely extensive discussion of this in the archive.

I think the easiest is to get the new key value from the db before you
start the insertion process. One way is through a session bean. If mySQL
only supports autoincrement rather than generators(interbase/firebird) or
sequences(oracle) you will have to create a 1-column table for each key
sequence you want.
