Hi,
1. From several emails of EJB-list:
one of the reasons of "EJB forbids file I/O" is for "making EJB portable
over kinds of EJB containers on kinds of oprating systems". So it is
better
not to use "file accessing" from EJB.
2. From my work:
with J2EE1.2.1+winnt40, by adding the following permission
into ...\j2sdkee1.2.1\lib\security\server.policy:
permission java.io.FilePermission "<<ALL FILES>>", "read,write,delete";
I can read file form EJB.
