John,
the spec indeed mention the text you provide,
but what will be the drawbacks/penalties in still using the i.o package ?

Subject: Re: File I/O in an session EJB
This is a quote from the EJB spec:
An enterprise bean must not use the java.io package to attempt to access
files
and directo-ries
in the file system.
The file system APIs are not well-suited for business components to access
data. Business components
should use a resource manager API, such as JDBC API, to store data.
� An enterprise bean must not attempt to listen on a socket, accept
connections
on a socket, or
use a socket for multicast.
