Creating a Socket to System.in ?

[FET]

Hello everyone,
I am in a slight soup here.
For people who are familiar with linux, I am trying to invoke a java
app using xinetd. I have gotten the app to run, but it doesn't perform
IO. Xinetd passes the socket descriptor as the standard input i.e
System.in. Therefore, I can simply do BufferedInputStream(System.in)
and then read() from it.
But the problem is, how do I write results back to this stream ?
Please advise.

Thanks in advance.
Regards.

Write to stdout (System.out).

I haven't tried it, just ideas:
If xinetd writes to stdin of your application it propably also reads from
stdout?
If this doesn't work you could try to use the redirect option of xinetd to
lead to another (local host and) port where your java app resides.

you don't mean to write to the input do you?
if you do, then do you want your program read what you wrote?
