IllegalStateException problem

[Joshua Antony]

PrintWriter writer = res.getWriter();
writer.println("Test");
writer.flush();
writer.println("After Flush");

Above is part of a code in a Servlet.
But I am not getting IllegalStateException in the line
writer.println("After Flush"); although I have committed the response
the line before.

Where am I going wrong?

Regards,
Joshua

Nothing prevents you from outputting after it has been flushed.

No method of PrintWriter class throws IllegalStateException. You will get IllegalStateException if you try to forward the request to other page after calling flush().
