Hi Rajesh,
Yes, your assignment is still valid, and I think there is one (or maybe 2) other people still working on Fly By Night Services here in this forum. So
you should still be able to get help.
It is worth noting that almost all of the problems that can occur in FBBS can also occur in the later assignments (B&S or URLyBird). So talking about the problem and not the assignment will probably result in more help being provided. The major exceptions, of course, are fixing the deprecated methods in the Data class - they dont occur in the later assignments.
The written exam is still almost exactly the same as if you had done it in 2002. The difference is that they dropped a question (it used to be five questions, now it is four). But the questions themselves apply to any assignment, so they will still apply to FBNS.
Although it is not a requirement for you, I strongly recommend you use JDK 5 for your assignment. The assessor will be expecting it, and there are all sorts of benefits from using it.
Regards, Andrew
