python raw_input after sys.stdin read

Question

I've got problem with following lines. First I read from STDIN (one line from a Java program STOUT), then I would like to read from prompt in the Python (2.7) program.

for line in sys.stdin:
    c = line.split()
    break;
//
// do stuff
//
val = raw_input()
print(val)

which return:

Traceback (most recent call last):
  File "test.py", line 6, in <module>
    val = raw_input()
EOFError: EOF when reading a line

How to stop reading from STDIN and read from the prompt? Thanks, Nicolas
