File is a file in IFS.
Here is a more complete piece of code. The Java program reads a text file
from a directory and places is on a queue (MQ).
There is nothing to do with stdin, and sometimes it works.
This runs on a OS400 5.4 , JVM 1.4.


FileInputStream fstream = new FileInputStream(file);

if (fstream.available() > Integer.MAX_VALUE)
   System.out.println("File '" + file + "' is too big.");
int buffersize = fstream.available();
byte[] contents = new byte[buffersize];;

long n = fstream.read(contents, 0, buffersize);
fstream.close();
fstream = null;
if (n != buffersize)
  System.out.println("Error in reading file '" + file + "'");
else
message = new String(contents);

The error seems pretty self explanatory to me ... stdin (which appears
to be basic keyboard input in this context) is only available when a
program is run interactively.  When you run in batch, stdin isn't
available.

What's the value of 'file'?
