Hi,
After looking at these messages, I got a question.
Some of U people suggested not to perform any kind of I/O operations (using
flat files) with EJBs.
We are thinking of using EJBs in our product. And in our product, we use
some third party libraries written in "C", which will create some indexs
into flat files. For all queries, this (third-pary) library acesses these
flat files. Then do U say that, EJBs is not for us.
Thanks in advance for any clue.
- Raj.
