That is scanner dependent. You will have to read the developer guide of your scanner to learn how to interact with it.Assuming I have a scanner, when the item gets scanned where does it store that code
A scanner does not scan this info. It only scans codes.Also how can I find the item name, for example if bread is scanned I do not want the brand name bread.
Only the item eg it has to return "bread"
Sorry, I do not get the link between what you do with the scanner and what your web application should do. Can you please explain the scenario?If it is web based application, can this stored in a database and then displayed in jsp?

You will need to store a translation table between these codes and the display label somewhere.
The user will login to the web application. For entering the ingredients required for the recipe , the user will scan the items. The scanned items will be displayed to the user. (eg: bread, butter,pepper etc). The user enters the quantity of each these scanned items.
I thought the code for each item is unique ie for example Brand name A Bread has a unique code and Brand name B Bread has a different code.

That most likely means a signed applet that interacts with the scanner and the various pages of the web app.
They must have used a cross reference in the background. Barcodes don't carry that info.Recently I had seen an android app, that lets you take a picture of the bar code and the app returns the details of the item.
Not sure how they do it.

Can you please elaborate on how to achieve this?

Our customers subscribe to this pool, and can receive that data (security is involved, we can say which partners get the data).
There are rules on when and how data is provided and changed. Our customers never have goods from us in their shop that they don't know of.
They can *rely* on having the data. The website below can't.
