This code is from core servlets and JavaServer Pages(2nd Edition) by Marty Hall. i want to know how i can change the code below to list the items available in inventory from a database(Microsoft Office Access)(table name is tbltemDetail).As the code after the new Item is place there using a static table.Actually i want to use a array to store the info from the ResultSet.

private static Item[] items =
{ new Item("hall002",

You would need a database. I'll move this to the [b]JDBC[/i] forum for you.

Its better to use VO/TO, Value Object/Transfer Object, to store the resultset values and place them into any suitable collection object.

You can iterate over that collection to render those items into your html table.

Best is to use JSP for presentation, instead of doing it all in a servlet.

As i have created a lots of classes of related i hope that this can be done in servlet. Can anyone provide the code for me of how to retrieve the static table of the given codes. as i already have a table of the item i wish to place into the interface.

How i can use an array to retrieve information from a resultSet. and loop through to replace the new CatalogItem{"lewis001","description"} instead of placing the static codes
