Why EJBs are not allowed to make use of java.io package?
I am able to write EJB which read file from filesystem without any problem.

It is forbidden by the specification. Please see section 21.1.2:
• 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, to store data.
