I don't think it is a good idea to use ObjectStore directly from inside an
EJBean. For instance, ObjectStore's transactions should be mapped in some
way to app server transactions such that when the container decides to
commit/rollback the ObjectStore transactions commit/rollback as well (in
other words ObjectStore should behave like an XAResource).
eXcelon sells a special product, Javlin, that (amongst other) supports this
integration.
However, as far as I know, Javlin currently only works with weblogic.
Integration with other app servers seems to be on their list (check
www.exceloncorp.com).

PS: The crash might be related to the fact that IAS might prohibit EJBeans
to dynamically load native libraries, but this is just my own wild guess ...
PPS: I am not related to eXcelon, we're just using their products within a
weblogic context.
