flying-saucer-pdf Table 'name' does not exist in exception on ubuntu

Question

I have a simple spring boot web app, where i create downloadable pdf with flying-saucer-pdf from html that i render with thymeleaf. It's work well and generate the html string correctly. I develop on windows and during develop generating the pdf is also works well, but on ubuntu server don't work.

    ITextRenderer renderer = new ITextRenderer();
    renderer.getFontResolver().addFont(fontFile, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

fontFile is exist, on ubuntu too, it's accessibly by the program, and can access it, but when i want render a pdf i got the following exception. I have no ide what actually it means.

Caused by: com.lowagie.text.DocumentException: Table 'name' does not exist in /opt/RFIT/TextileApp/conf/font/Rubik-Regular.ttf at com.lowagie.text.pdf.TrueTypeFont.getBaseFont(Unknown Source) ~[itext-2.1.7.jar:na] at com.lowagie.text.pdf.TrueTypeFont.process(Unknown Source) ~[itext-2.1.7.jar:na] at com.lowagie.text.pdf.TrueTypeFontUnicode.(Unknown Source) ~[itext-2.1.7.jar:na] at com.lowagie.text.pdf.BaseFont.createFont(Unknown Source) ~[itext-2.1.7.jar:na] at com.lowagie.text.pdf.BaseFont.createFont(Unknown Source) ~[itext-2.1.7.jar:na] at com.lowagie.text.pdf.BaseFont.createFont(Unknown Source) ~[itext-2.1.7.jar:na] at org.xhtmlrenderer.pdf.ITextFontResolver.addFont(ITextFontResolver.java:201) ~[flying-saucer-pdf-9.1.6.jar:na] at org.xhtmlrenderer.pdf.ITextFontResolver.addFont(ITextFontResolver.java:193) ~[flying-saucer-pdf-9.1.6.jar:na] at org.xhtmlrenderer.pdf.ITextFontResolver.addFont(ITextFontResolver.java:188) ~[flying-saucer-pdf-9.1.6.jar:na] at hu.rfit.textile.service.impl.PdfPrinterService.printPDF(PdfPrinterService.java:53) ~[TextileApp-1.0.0-SNAPSHOT.jar:1.0.0-SNAPSHOT:4749]

on some forum they said i should add the font to /usr/share/fonts dirt, and re build the font cache. But it's does not work.

Answer 1

I had same problem about adding font with flying-saucher. Problems main cause is cropped font file. Your operating system or maven filtering may cause this problem. In my example, i used maven and following steps are solved the problem.

If you are using maven, you should add font file to your resource folder.

For example,

src/main/resources/fonts/samplefont.ttf

After that, you should define resources on pom.xml like following;

        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <excludes>
                    <exclude>fonts/*</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>false</filtering>
                <includes>
                    <include>fonts/*</include>
                </includes>
            </resource>
        </resources>

After that, you can use following definition,

ITextRenderer renderer = new ITextRenderer();
renderer.getFontResolver().addFont("/fonts/samplefont.ttf",
                                    BaseFont.IDENTITY_H,
                                    BaseFont.EMBEDDED);

I hope it will be helpful.
