}

private static String execPerl(String fileName){
String cmd = "";
String msg = "";
String brs = "";
cmd = "perl " + fileName;
try {
Process pro = Runtime.getRuntime().exec(cmd);
InputStream ins = pro.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(ins));
while((brs = br.readLine()) != null){
msg += brs;
}
} catch (IOException e) {
e.printStackTrace();
}
return msg;
}
