Pipe

[budavargas]

Hola:

Prueba con algo asi. Un ejemplo usando GNUPLOT, con uso de las "pipas" de entrada, salida y error:

{...
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("gnuplot");
PrintWriter outPlot = new PrintWriter(
new BufferedWriter(
new OutputStreamWriter(
process.getOutputStream())));

BuffererReader inPlot = new BufferedReader(
new InputStreamReader(
process.getInputStream()));

BuffererReader errPlot = new BufferedReader(
new InputStreamReader(
process.getErrorStream()));

outPlot.println("plot sin(x)"); // ejemplo

outPlot.close();
inPlot.close();
errPlot.close();
...}

Saludos
