Cannot read from file

P: 31
Hello. I am trying to read the number of lines in a file using this function

Expand|Select|Wrap|Line Numbers
  1. static int NumberofLines(String file) throws IOException{
  2.         RandomAccessFile reader = null;
  3.         int lineCount = 0;    
  4.         try {
  5.             reader = new RandomAccessFile(file + "/perso.txt", "r");
  6.             for (String line = reader.readLine(); line != null;
  7.                     line = reader.readLine()) {
  8.                 lineCount++;
  9.             }
  10.         } catch (IOException e) {
  11.             System.err.format("Could not read %s: %s%n", file, e);
  12.             System.exit(1);
  13.         } finally {
  14.             if (reader != null) {
  15.                 try {
  16.                     reader.close();
  17.                 } catch (IOException e) {}
  18.             }
  19.         }
  20.         System.out.println("Number of Lines are " + lineCount);
  21.         return lineCount;
  22.     }
However I get the following error when I try and run my program I get the following error: -

Read the error text: a file name cannot contain IP addresses or host names.
Use a URL instead given that name, connect it and get an InputStream from that
connection. Start at the API documentation for the URL class.

kind regards,

The file could contain an ip address using the previous run time environment. This program ran using an ip address and was working before. Is it the change in run time environment that caused this?
