I've already given the same topic and couldn't solve the problem yet. Thanks and regards
The topic you're referring to is this one: http://www.coderanch.com/t/291466/JSP/java/LinkedList-Problems-JSP and a lot of people put in time to help you with it. Please don't spread the same conversation across different threads. It gets confusing and wastes the time of the people who are trying to help you.
Go back and look at the answers in that thread, I think you will find the answer there.
