barcode4j example in CFML / Lucee

barcode4j.cfm

<cfset jarsPath = expandPath('/java/barcode4j/') />
<!--- Path where the necessary jar files are located (downloadable from https://www.dropbox.com/s/skl9fwky2n7mnjr/java-files-barcode4j.zip?dl=0) --->

<cfset libraryList = arrayToList( directoryList(jarsPath, false, 'array', '*.jar') ) />
<cfset configBuilder = createObject('java', 'org.apache.avalon.framework.configuration.DefaultConfigurationBuilder', libraryList) />
<cfset barcodeUtil = createObject('java', 'org.krysalis.barcode4j.BarcodeUtil', libraryList) />
<cfset grayImageType = createObject('java', 'java.awt.image.BufferedImage').TYPE_BYTE_GRAY />

<!--- create custom config. See http://barcode4j.sourceforge.net/2.1/symbol-ean-13.html --->
<cfset configXml = '<barcode>
	<ean-13>
		<height>10mm</height>
		<quiet-zone enabled="false">1mm</quiet-zone>
		<checksum>ignore</checksum>
		<human-readable>
			<placement>none</placement>
		</human-readable>
	</ean-13>
</barcode>' />
<!--- config needs to come from file, it seems. So writing it to tempDir first --->
<cfset fileWrite(getTempDirectory() & "barcodeconfig.xml", configXml) />
<cfset barcodeConfig = configBuilder.buildFromFile( createObject('java','java.io.File').init("#getTempDirectory()#barcodeconfig.xml") ) />
<!--- the barcode generator object --->
<cfset gen = barcodeUtil.getInstance().createBarcodeGenerator( barcodeConfig ) />

<!--- path to save the barcode images to --->
<cfset barcodedirpath = expandPath("/barcodefiles/") />


<cfset barcode = "0075678164125" />

	<!--- create barcode image --->
	<cfset imgPath = barcodedirpath & "#barcode#.png" />
	<cfset outStream = createObject('java', 'java.io.FileOutputStream').init( createObject('java','java.io.File').init(imgPath) ) />

	<cfset provider = createObject('java', 'org.krysalis.barcode4j.output.bitmap.BitmapCanvasProvider', libraryList)
			.init(outStream, "image/x-png", 300, grayImageType, true, 0) />
	<cfset gen.generateBarcode(provider, barcode) />
	<cfset provider.finish() />
	<cfset outStream.close() />
 

This is very helpful. Thank you so much for sharing, Paul!
