PropertySet properties = entity.getPropertySet();

where entity is either user or group. 
Now you can set/get properties through it.

Yes. Though not actually eagerly require, but 
they are accessible through property set.

PropertySet properties = user.getPropertySet();
String sex = properties.get("user_sex");

properties.setString("user_sex","daily");

It does not care about it. It's up on your
application.

You are damn right... Though carefull reading of code
sheds some light :) I'm even able to patch
and improve  hibernate providers now :)

Dunno. I never used OSaccess....  You'll have to look
for CVS logs to determine activeness of each of
projects. 


Any my code sample demonstrates how to populate java
bean from property set, and also to save it.
