I tried something like this:

try {
           Process p = Runtime.getRuntime().exec("somepathto\
\some.exe");

           String line = null;

           BufferedReader read = new BufferedReader(new
InputStreamReader(p.getInputStream()));

           while((line = read.readLine()) != null) {
               System.out.println(line);
           }
           int exitVal = p.waitFor();
           System.out.println("Exit value = " + exitVal);
      }
       catch (Throwable e) {
           e.printStackTrace();
       }

...but it doesn't work.
When I try to read one by one character (using read() method) it
produces some output, but not all.

Can anyone help me? Thanks in advance. :)
