Barcode generation and printing from customized Oracle form

Our client needs to label its finished good items with bar codes, as they are produced.

The simplified process is as follows:

1. Finished good units arrive on a belt onto a weighing scale one by one.

2. Each units weight and item code is entered by user on customized Oracle form.

    (One line is entered for each unit as the items are serial controlled)

3. For each unit, user clicks "Generate Bar Code" button.

   This initiates a request which generates a bar code and provides output in Pdf file.

4. User prints the bar code in pdf file from Zebra printer.

    The bar code is then attached to unit.
