problems with getOutputStream of Runtime.exec

Hi, I have a problem with the method getOutputStream() of the Process generated by Runtime.exec

I need java to execute the command

Bioinfo/ncoils/ncoils -f < template.fasta

My code is:

Process p = Runtime.getRuntime().exec("Bioinfo/ncoils/ncoils -f");

BufferedReader in = new BufferedReader(new FileReader("template.fasta"));

String line;

OutputStream os = p.getOutputStream();

PrintWriter w1 = new PrintWriter(os);

while( (line=in.readLine()) != null) w1.println(line);

in.close();

os.close();

w1.close();

p.waitFor()

But the program ncoils actsas if it has not received any input .....

Could you help me find what's wrong?

Thanks a lot! Francesco
