Cindy,

The EJB specification prohibits writing to files. EJB�s are transactional and 
clusterable objects. files can neither take part in transactions nor can the be 
written to in a cluster.

Imagine you deploy yor bean in a cluster containing 10 boxes. you will never know 
which ejb will write to the file and on what box.

Saravana,

Thanks for responding to my email. You are  suggesting that EJBs can access
file I/O indirectly through some helper classes. But my understanding is that
EJB can not access file I/O either directly or indirectly.
