Font Extension for barcode in report

I want to add Barcode font39 to my JR report. As given in the JasperReports tutorial, I have packed my fonts.xml, .ttf and the jasperreports_extension.properties in a jar and included this jar in classpath.

My fonts.xml content is as:

<fontFamilies>
    <fontFamily name="Barcode">
        <normal>net/sf/jasperreports/fonts/barcode/ConnectCode39_S3_Trial.ttf</normal>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
    </fontFamily>
</fontFamilies>

The jasperreports_extension.properties file:

net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.myFamily=net/sf/jasperreports/fonts/fonts.xml

However when run, I get the following exception:

What am I doing wrong?
