Thanks a lot Jeff ! The problem is that everytime I build (using ant ) there is a build folder created. But there is no examples.jar created inside that. I wanted to add some files into io package and mapred package. So I suppose I should put the files appropriately ( inside io and mapred folder respectively). I want to run the Sort in examples.jar using these added classes. I guess I can import these new files in the Sort code and build the entire thing again.
But I am not able to figure out how to rebuild these core containing jar and examples jar with the modified sort.
