I have a problem When I tried to convert .jrPrint file with Thai text to .pdf file here's my file when I opened on JasperSoft. My Thai text show the result is □□□ (Square), And the English text show it usually. Here is my code in Java Spring Boot Project
package com.nattatat.jrPrintToPdf.Service;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.stereotype.Service;
import net.sf.jasperreports.engine.JRException;

import com.itextpdf.pdfa.PdfADocument;
import java.io.*;
@Service
public class JasperReportService{
protected final static Logger log = LogManager.getLogger(JasperReportService.class);
public void convertJrprintToPdf(String jrPrintFilePath, String pdfOutputPath) {
log.info("\noutput: " + pdfOutputPath);
try {
JasperPrint jasperPrint = (JasperPrint) JRLoader.loadObjectFromFile(jrPrintFilePath);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
// Set the export font map for PDF
JRPdfExporter exporter = new JRPdfExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream);
exporter.setParameter(JRPdfExporterParameter.CHARACTER_ENCODING, "UTF-8");
exporter.exportReport();
JasperExportManager.exportReportToPdfFile(jasperPrint, pdfOutputPath);
byte[] byteArray = outputStream.toByteArray();
// Save the byte array to a file (optional)
try (FileOutputStream fileOutputStream = new FileOutputStream(pdfOutputPath)) {
fileOutputStream.write(byteArray);
System.out.println("PDF file saved successfully.");
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("PDF exported successfully.");
} catch (JRException e) {
e.printStackTrace();
System.out.println("Error exporting to PDF.");
}
}
public void convertJrprintToPdfa(String jrPrintFilePath, String pdfOutputPath) throws FileNotFoundException {
try {
// Load .jrprint file
JasperPrint jasperPrint = (JasperPrint) JRLoader.loadObject(new File(jrPrintFilePath));
FileOutputStream fileOutputStream = new FileOutputStream(pdfOutputPath);
// Create PdfAWriter
PdfWriter pdfWriter = new PdfWriter(fileOutputStream);
PdfADocument pdfADocument = new PdfADocument(pdfWriter, PdfAConformanceLevel.PDF_A_1B,
new PdfOutputIntent("Custom", "", "http://www.color.org", "sRGB IEC61966-2.1", null));
// Create JasperReports exporter
JRPdfExporter exporter = new JRPdfExporter();
// Configure exporter
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, fileOutputStream);
exporter.setParameter(JRPdfExporterParameter.CHARACTER_ENCODING, "UTF-8");
// Export the report to PDF/A
exporter.exportReport();
// Close the PdfADocument
pdfADocument.close();
System.out.println("PDF exported successfully.");
} catch (JRException | IOException e) {
e.printStackTrace();
}
}
}
And this is my fonts.xml for embedded font
<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
<!-- The jrprint file use this font families. -->
<fontFamily name="TH Sarabun New">
<normal><![CDATA[fonts/TH Sarabun New/THSarabunNew.ttf]]></normal>

From these code I used. The .pdf result didn't show Thai text (Show only English text).
