discussed on the list in the past - take a look at the archives.
Many of the problems derive from I/O restrictions in an EJB system. Most
solutions suggest some variant of JMS or RMI to take the logging outside
of the container.

settings that can be read as required. This seems to be direction that
the EJB spec is heading (see EJB 1.1. and the emphasis on JNDI to
configure the application).
You will also probably want to look at the recent posts on business vs
remote exceptions.
