Hi,

I have had this problem for a long time now:

I have written a programme that searches for email IDs in any file. The
relevant piece of code goes like this:

  String strRe=new String("[a-z0-9\\.\\-\\_]+@(([a-z0-9\\-\\_])+\\.)+(" +
     "com|net|org|edu|int|mil|gov|arpa|biz|" +
     "aero|name|coop|info|pro|museum|tv|[a-z]{2})");

  try {
   pattern = compiler.compile(strRe,AwkCompiler.CASE_INSENSITIVE_MASK);
  } catch(MalformedPatternException e) {
   System.out.println("Internal error.\n"+e);
   return;
  }

---

  String content=null;
  Reader rin=null;
  try {
   rin=new FileReader(fileName);
  }
  catch (Exception e) {
   // do nothing.
   return;
  }

  AwkStreamInput input=new AwkStreamInput(rin);
  boolean hasPrinted=false;

  try {
   while (matcher.contains(input, pattern)) {
    MatchResult result = matcher.getMatch();
    if (comma)
     if (!hasPrinted)
      System.out.print(result);
     else
      System.out.print(", "+result);
    else
     System.out.println(result);
    hasPrinted=true;
   }
  }
  catch (IOException ioe) {
   // just ignore.
  }


However, when I try to use this to search into a binary file (esp. a JAR
file), it gives me

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
        at org.apache.oro.text.awk.AwkMatcher._search(AwkMatcher.java:717)
        at org.apache.oro.text.awk.AwkMatcher.contains(AwkMatcher.java:622)
        at com.seeingwithc.email.Emails.handleFile(Emails.java:76)
        at com.seeingwithc.email.Emails.main(Emails.java:51)

Please help me with this...
