How to update JList and JTextfield with database HSQLDB?

I use Eclipse and my database is hsqldb. I have a JFrame with 3 JPanel.

In my first JPanel, I have 3 JList, Category, Brands and Product.

In my database, I have a table category (id, name) brands (id, name) product (id, product, price, description, quantity + foreign key on category and Brands).

I started coding but I can not do that when I select one item in JList category and brand, I have to bring up the result in product (one item or multiple) and when I select one item in Jlist Product, I have to bring up the result in the JPanel Informations (price, description and quantity).

Thanks for you help,
