help: a newbie question

Hi,

I am new to javacc and have a question to ask. I wrote a very simple javacc
code but it could not parse a simple input with ".".

The javacc code:

 PARSER_BEGIN(SimpleTest)

public class SimpleTest {

  public static void main(String args[]) throws ParseException {
    SimpleTest parser = new SimpleTest(System.in);
    parser.Input();
  }

}

PARSER_END(SimpleTest)

SKIP :
{
  " "
| "\t"
| "\f"
| "\n"
| "\r"
}

TOKEN :
{
  < FIND : "find" >
|
  < AS : "as" >
|
  < DOT: ".">
|
  < ID: ["a"-"z","A"-"Z","_","@"] ( ["a"-"z","A"-"Z","_","0"-"9","@"] )* >
|
  < STRING_LITERAL:
      "\""
      (   (~["\"","\n","\r"])
      )*
      "\""
  >
}

void Input() :
{
  Token type;
  Token subType;
  Token name;
  Token id;
}
{
  LOOKAHEAD(<ID> <DOT>)
  <FIND> type=<ID> <DOT> subType=<ID> name=<STRING_LITERAL> <AS> id=<ID> ";"
  {
    System.out.println("find "+type+"."+subType+" "+name+" as "+id);
  }
  |
  <FIND> type=<ID> name=<STRING_LITERAL> <AS> id=<ID> ";"
  {
    System.out.println("find "+type+" "+name+" as "+id);
  }
}

The input I wanted to test is(from System.in):
        find Server.SSL "server.ssl" as s2;
        find Server "server" as s1;

Somehow the generated parser could not parse the first line. It kept
complaining:
    Encountered "." at line 1 column 12
    Was expecting:
    <STRING_LITERAL> ...

I do not understand why the LOOKAHEAD does not work. Could anyone give my
some help here? Thanks a lot!
