Java Code-39 Generator for Java, Jasper Reports, BIRT
Code-39 is also known as ANSI/AIM
Code 39, ANSI/AIM Code 39, Uniform Symbology Specification Code 39, USS Code
39, USS 39, Code 3/9, Code 3 of 9, USD-3, LOGMARS, Alpha39, Code 39 Extended,
and Code 39 Full ASCII
Code 39, the first alpha-numeric symbology to be developed, is still widely used-especially in non-retail environments. It is the standard bar code used by the United States Department of Defense, and is also used by the Health Industry Bar Code Council (HIBCC).
Our library fully complies with ISO/IEC 16388 (Second edition 2007-05-15).
There are two ways to create barcode images in your Java web applications.
This is the simplest way to stream barcode image using our provided barcode servlet classes.
And it will not save barcode images in your server side.
Under demo package, copy barcode folder to your java servlet container like tomcat.
To test your installation, goto http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODE39
To create barcode image in your JSP or html page, you can pass the url to IMG tag src value.
For example, <img src="http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODE39" />
The second method is similar with the way to generate barcode in Java applications.
Create a barcode image in server side
1 Linear linear = new Linear();
2 linear.setData("123456789");
3 linear.setType(Linear.CODE39);
4 linear.renderBarcode("C:/Tools/Tomcat 5.5/webapps/YourWebApp/bimages/barcode.gif");
In your JSP page, you can using IMG tag to display generated image, like <img src="http://YourDomain:Port/YourWebApp/bimages/barcode.gif" />
Set the type property to Linear.CODE39 or Linear.CODE39EX Servlet Parameter: "Type".
Set the data property with the value to encode. Type is string.
Servlet Parameter: "Data".
Setting up barcode image size:
Set property uom (Unit of Measure) for properties barWidth, barHeight, leftMargin, rightMargin, topMargin and bottomMargin.
Default is Linear.UOM_PIXEL (0). Valid values are Linear.UOM_PIXEL (0), Linear.UOM_CM (1), Linear.UOM_Inch (2).
Servlet Parameter: "UOM".
Set the X (for barcode module width) and Y (for barcode module height) properties. Both types are float.
Servlet Parameter: "X", "Y".
Set the leftMargin, rightMargin, topMargin and bottomMargin properties, and types are all float.
Servlet Parameter: "LeftMargin", "RightMargin", "TopMargin", "BottomMargin".
Set the barcodeWidth (barcode image width) and barcodeHeight (barcode image height) properties. Both types are float.
Servlet Parameter: "BarcodeWidth", "BarcodeHeight".
Set the resolution property (Value is expressed in DPI - Dots per inch).
Servlet Parameter: "Resolution".
Setting up text style in barcode image:
Set the showText properties. If this value is true, barcode data will be displayed with the barcode.
Servlet Parameter: "ShowText".
Set the textFont property. The font used to display text in barcode image.
Servlet Parameter: "TextFont".
Set bearerBars property, if you want to draw borders around barcode image. Value can be Linear.BEARERBAR_UNSPECIFIED (-1. let library decide whether draw bear bars or not), Linear.BEARERBAR_NONE (0. no bear bars), Linear.BEARERBAR_FRAME (1. top, bottom, left, right borders drawn), Linear.BEARERBAR_TOPBOTTOM (2. only top, bottom's are drawn).
Servlet Parameter: "BearerBars".
Set rotate property, if you want to rotate barcode image.
Value can be 0 (Linear.ANGLE_0),
1 (Linear.ANGLE_90),
2 (Linear.ANGLE_180),
3 (Linear.ANGLE_270)
Servlet Parameter: "Rotate".
addCheckSum property is optional. Modulo 43 will be applied, if addCheckSum property is true.
Servlet Parameter: "AddCheckSum".
To set barcode image width and height, there are two ways to do it.
1) You can set barcode image width and height through properties barcodeWidth and barcodeHeight values, barcode library will render the barcode image for you.
or
2) You can set X (barcode module width) and Y (barcode module height) values, barcode library will calculate the barcodeWidth and barcodeHeight values for you, and render the barcode image.
