This can apparently be done in Weblogic, at least(though the SPEC says not
to).
Maybe a better way is to farm your helper class out into a startup class,
from there
because it runs outside of the context of the EJB server thread control is
allowed.
I've done a threaded startup class in WL 4.5.1 and it works fine, though for
ease
of access it is probably better to make the started up class a singleton (if
you can).
