Using pipes

[McBugzz]

I start a new process via Runtime.getRuntime().exec(), and I need to send some data to it. The new process should receive some of the data that I send, and then create a yet another process, which has to start receiving the data instead of the first one.

I belive I should use the Pipe object here, but so far I haven't found a good sample or doc on using pipes.

Suggestions?

Thanx

If you get a Process object from your Runtime.exec() then you can call the getInputStream() and getOutputStream() methods in attach to the stdin and stdout handles of the process.

Process p = Runtime.getRuntime().exec(whatever);
...
InputStream is = p.getInputStream();
OutputStream is = p.getOutputStream();
...

Don't know what you mean by "Pipe object" ...
