Process and Streams

Question

I'm doing a program that will use psftp-program to transfer files to server. Part of the code is attached below.
Process yhteys = aja.exec("c:\\temp\\psftp [email protected] -bc -b tuo.src");
InputStream input = yhteys.getInputStream();
OutputStreamWriter out = new OutputStreamWriter( new BufferedOutputStream(yhteys.getOutputStream()) );
char merkki;
while ((merkki = (char)input.read()) != ':') {
System.out.print(merkki);
System.out.print(merkki);
out.write("salasana\n");
out.flush();
while ((merkki = (char)input.read()) != ':') {
System.out.print(merkki);
System.out.print(merkki);
input.close();
out.close();
yhteys.getErrorStream().close();
yhteys.destroy();This prints the following:
[email protected]'s password:
[email protected]'s password:So the input seems to work but out doesn't. Psftp doesn't seem to receive the password, because it keeps asking it after it should have been received.
How this data transfer in and out of process should be done right?

Answer 1

try using the ftp url in the following form:
nn:[email protected] ftp clients can correctly parse the format user:password@address url, since it is a standard. Anyway, if you want to dig deeper into Java, try to find a FTP library that can suit your needs. In that way, you won't need a 3rd party ftp client.
