problem with lexer.dat

Greetings everyone,

Btw, thanx alot for your help AND patience.


I have now constructed my min grammar file which goes like :


Package test;



   a = 'a';

   b = 'b';


   s = a s [second]:a |

            {alternative_two} b;


I generated all my classes and I implemented them in a main class …

However when I try to run the program I obtain the following error from the lexer.java class :


"The file \"lexer.dat\" is either missing or corrupted."


To make sure that the lexer.dat file is not missing I have put it in C: and change the code to :


           new BufferedInputStream(



However I still obtain the same error msg (The error occurs as soon as lexer tries to read the lexer.dat file in         int length = s.readInt();


As always your help is really appreciated
