Getting the right file path from a maven resource folder - iText

Question

As I'm using a external font for iText, I need to load the font file from my maven resource folder (src/main/resources) but the iText API requires me to provide a file path instead the file itself.

So, I'm having problems while trying to use this code:

String arialUnicodeFontPath = getClass().getClassLoader().getResource("arialuni.ttf").getPath();

BaseFont unicodeBaseFont =
        BaseFont.createFont(arialUnicodeFontPath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

I get this:

2016-08-18 09:17:12,667 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/pdfgen2].[controlServlet]] (http-/0.0.0.0:8443-1) JBWEB000236: Servlet.service() for servlet controlServlet threw exception: java.io.IOException: /content/pdfgen2.war/WEB-INF/classes/arialuni.ttf not found as file or resource.

Answer 1

I couldn't find a solution to load the file by it's path the way i wanted but i used a workaround to get the itext font the way i needed with the follow code:

byte[] fontByte = IOUtils
    .toByteArray(this.getClass().getClassLoader().getResourceAsStream("/fonts/arialuni.ttf"));
BaseFont unicodeBaseFont = BaseFont.createFont("arialuni.ttf", BaseFont.IDENTITY_H,
    BaseFont.EMBEDDED, true, fontByte, null);
