I am not sure why you keep using the plural we instead of I but I have the feeling that this doesn't have anything to do with the SCEA exam. The SCEA assignment does not have an "executable". Are you referring to the SCJD assignment?

Bala,
Please don't cross post.
Everyone - please post responses (if any) to this thread in the Java in General (advanced) forum.
Thanks, Andrew
