Barcode4j not working (on Unix)

Question

For my project, I need to generate a barcode for a PDF.

I have been able to successfully generate barcodes on my local Windows Server, on the production UNIX server, the generation fails though.

I use barcode4j and need to generated code39.

My template :

<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:fo="http://www.w3.org/1999/XSL/Format" 
    xmlns:bc="http://barcode4j.krysalis.org/ns" 
    xmlns:barcode="org.krysalis.barcode4j.xalan.BarcodeExt" 
    extension-element-prefixes="barcode"
    exclude-result-prefixes="fo">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" omit-xml-declaration="no" indent="yes"/>
    <xsl:param name="versionParam" select="'1.0'"/> 

    <xsl:template match="anforderung">
        <xsl:call-template name="barcode">

    </xsl:template>

    <xsl:template name="barcode">

Answer 1

Perhaps check what version of java you are running (java -version).

Some programs do not operate properly if you are using GJC for example. In that case get OpenJDK or the Oracle JDK and try again.

Answer 2

NoSuchMethodError in the Avalon Framework class DefaultConfiguration means you may have an older Avalon Framework in the classpath. Please make sure you have Avalon Framework 4.2.0 or later. You can find it in Barcode4J's lib directory.
