Hi Roman,

Thanks for your emails. I am using JDK 1.6 and this probably caused the 
version issue. In any case I have re-compiled the sources and generated 
the jar and the corresponding files with JDK 1.5. The file are now 
committed. I tested it on my machine and it is working ... I found a 
neat package for calculating signatures and developed a helper class 
(named Makefile) for automating this process. Please find attached a 
tar-gziped file containing three files:

1) USAGE file
2) jacksum.jar
3) jacksum-src.jar

Class Makefile is located within jacksum package.  If it is useful for 
developers we could probably add it to the repository to automate this 
process.

Best regards,
-P.
