Both barcode.jsp and BarcodeServlet represent a barcode image. You use them the same way you would a CGI program. They are only provided as a reference and for your convenience. If you are a Java programmer, you can modify their content anyway you see fit.

Parameters
All the parameters are optional:
image
Numeric value indicating the image format:
type
Numeric value indicating the barcode type
data
String specifying the barcode data
addOnData
String specifying the barcode add-on data if the barcode has an add-on
rotation
Numeric value indicating the rotation of the barcode image. Note that gui=true is no longer necessary as of V3.1 of Barcode/JSP for rotation to take place.
height
Numeric value indicating the height of the barcode image in screen pixels
barWidth
Numeric value indicating the width of the thinnest barcode bar in screen pixels
caption
String specifying the barcode caption
addOnCaption
String specifying the barcode add-on caption
fontName
String specifying the name of the font to be used (Serif, SansSerif, Dialog or DialogInput). For this to be effective, you must also set gui=true currently, otherwise you'll always end up with SansSerif.
fontSize
Numeric (integer) specifying the point size of the font to be used
gui
Boolean indicating whether the barcode generation process should use GUI features (i.e., JDK AWT):
Remarks
BarcodeServlet and barcode.jsp generate barcode images dynamically in the PNG or JPEG format.
They use only a subset of the properties provided by the component com.bokai.barcode.Barcode. If need be, you can modify their content to set other properties like text position, etc.
