Re: [Simple-support] Multiple Objects in One File

[Niall G. <gal...@ya...>]

Hi,

So are you writing multiple separate objects to the
file or are you writing one large object. The ids
should not repeat as each write and read operation
gets a new session created, so although the ids may be
the same you will be able to deserialize them
separately without any issues using the Persister. 

However if your document is for external consumption
by DOM or SAX or something similar then overriding the
getKey() object seems like a reasonable solution.
