Thanks Ikegami for pointing out my mistake. I'm sorry for that...And I have read about the "STUDYING" Section. Yah it should help me. But I am totally new to Java..so I shall take some time in understanding the terms..Meanwhile I wish my code to be fully Perl-oriented i.e to minimise the use of other language applications...So it would be of great help if you could suggest some perl modules for the same task
