Problem in search Issue

Question

Hi there
I am creating a Library System. Here i provide a facility User to Search the Books by Title, Author , Category, Publisher.
In my program Book details are stored in the Books table in the Database When User wants to search a Book By Category, it has to select those category alone and store Them in BSearch table in the database.
When User clicks on Find Book Button. it has display all the available books Equal to that Category should be displayed on the JTable which is in another Form.
Here it works well for me. But the Problem is it shows only one Book on the JTable though there are Many Books in the Same Category.
Here i am posting my code
Code for SearchBook.java
