barbecue Barbecue Sample Shows how barcodes could be included in reports using the Barbecue component. Shows how to render barcodes in a report, using the barcode component based on the Barbecue library. 3.5.2 Sanda Zaharia shertage@users.sourceforge.net The Barbecue Library

As shown in the Barcodes section, the use of barcodes became universal. Depending on particular needs, there are several barcode specifications, called symbologies. This sample illustrates how to use the built-in component based on the open source Barbecue library.

The Barbecue library supports the following barcode formats:
  • 2 of 7 (Codabar)
  • 3 of 9 (Code 39)
  • Bookland
  • Codabar
  • Code 128
  • Code 128A
  • Code 128B
  • Code 128C
  • Code 39
  • Code 39 (Extended)
  • EAN 128
  • EAN 13
  • Global Trade Item Number
  • Interleave 2 of 5
  • Monarch
  • NW7
  • PDF417
  • PostNet
  • Random Weight UPCA
  • SCC-14 Shipping Code
  • Shipment Identification Number
  • SSCC-18
  • Standard 2 of 5
  • UCC 128
  • UPCA
  • USD-3
  • USD-4
  • USPS
It also provides support for multiple output formats:
  • PNG
  • GIF
  • JPEG
The Barbecue Component

According to the barbecue element in the components.xsd schema, to completely determine a barcode, the following pieces are needed:

Elements:
  • codeExpression - representing the alphanumeric character sequence for the barcode
  • applicationIdentifierExpression - useful when the UCCEAN128Barcode class is involved, to distinguis between various barcode providers.
Attributes:
  • type - determines the symbology used to generate the barcode. Allowed values are:
    • 2of7
    • 3of9
    • Bookland
    • Codabar
    • Code128
    • Code128A
    • Code128B
    • Code128C
    • Code39
    • Code39 (Extended)
    • EAN128
    • EAN13
    • GlobalTradeItemNumber
    • Int2of5
    • Monarch
    • NW7
    • PDF417
    • PostNet
    • RandomWeightUPCA
    • SCC14ShippingCode
    • ShipmentIdentificationNumber
    • SSCC18
    • Std2of5
    • UCC128
    • UPCA
    • USD3
    • USD4
    • USPS
  • drawText - specifies whether the text information should be visible in the generated barcode
  • checksumRequired - specifies whether the checksum is required for the barcode
  • barWidth - represents the width (in pixels) of the thinnest bar in the barcode
  • barHeight - represents the height (in pixels) for the bars in the barcode
  • evaluationTime - represents the report element evaluation time
  • evaluationGroup - represents the report element evaluation group name
  • rotation - represents the type of orientation for the barcode object.Allowed values are:
    • None
    • Left
    • Right
    • UpsideDown

Running the Sample

Running the sample requires the Apache Ant library. Make sure that ant is already installed on your system (version 1.5 or later).
In a command prompt/terminal window set the current folder to demo/samples/barbecue within the JasperReports source project and run the > ant test view command.
It will generate all supported document types containing the sample report in the demo/samples/barbecue/build/reports directory.
Then the report will open in the JasperReports internal viewer.
