Hibernate version:

2.1.6

Name and version of the database you are using:

mysql 4.0.22

Web application running on jboss 3.2.x with hibernate sar file. Two installations (each has own db) - each identical except that on one side the admin GUI is compiled in - on the other it is not. The hibernate config is identical on both sides.

Process - user inside uses admin GUI to control database. All hibernate classes are set with identifier to be native (which then uses MySQLs auto_increment ids as far as I can see).

When all is correctly changed - the user can then "publish" to the second installation via a SOAP connection.

So - in the internal version the use of identifier from MySQL is OK - but in the external one I need to be able to specify the id so that the two systems can synchronise.

I know I can use assigned ids but I'd like to keep the two systems as near identical as possible (all hibernate config is generated from xdoclet comments - would really like to avoid two versions).

Looking at the code - I can't figure out what will happen if an ID is present in an object passed to save() - will it be the same as MySQL where you can set the ID? I will give it a try to see if it works - but - any suggestions on a better method? Will this cause problems with future releases if I rely on it?
