Nothing has changed. The spec states:
"An enterprise bean must not use the java.io package to attempt to access
files and directories 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."
But, of course, we can all think of many situations where we want to use I/O
that has nothing to due with transactional issues. Most EJB servers do not
prevent you from performing file I/O. Do any?
