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. sven -----Original Message----- From: Cindy hao [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 15, 2003 2:55 PM To: [EMAIL PROTECTED] Subject: Re: File I/O in EJBs 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.
