Following my own thread: Here is the code snippet that works so far:

<%@page import="java.io.*" %>
<%  
    try {
      int b;
      Runtime runner= Runtime.getRuntime();
      String cmd="DIR";
      Process p=runner.exec(cmd);
      InputStream i=p.getInputStream();
      out.println("<html><pre><b>"+ "Executing:</b>" +cmd+"<br>"+"<b>Result:</b>");
      out.flush();
      while((b=i.read()) >=0) {
              out.write(b);out.flush();
      }
      out.println("</html>");
     } catch(Exception e) {
                    out.println("exception occured");
                    out.flush();
                    e.printStackTrace();
     }
%>

But how can I pass arguments from a FORM now?
