Jasper report export to pdf gives exception: java.lang.ClassNotFoundException: com.lowagie.text.pdf.PdfContentByte [duplicate]

This question already has an answer here:

I have been looking into this for hours but I didn't find any helpful resources

I am trying to export Jasper reports as pdf inside spring boot app, but I get an exception (shown in the end of the question)

I am not very sure but I found a link that states that the exporter is using old version of itext dependency (which was called com.lowagie.text; new ones are com.itextpdf.text as per the link) but still it didn't mention how to solve this issue

My code is this:

public void getRpt2(HttpServletResponse response) throws JRException, IOException, SQLException {

System.out.println("get resource!!! ...");
InputStream appCreatedReportStream
= getClass().getResourceAsStream("/jasperReports/App_created_en.jrxml");
System.out.println("Start compiling!!! ...");
JasperReport jasperReport
= JasperCompileManager.compileReport(appCreatedReportStream);

// should save the report to avoid long compile time
JRSaver.saveObject(jasperReport, "App_created_en.jasper");

Map<String, Object> parameters = new HashMap<>();

System.out.println("fill report!!! ...");

Connection connection = dataSource.getConnection();

JasperPrint jasperPrint = JasperFillManager.fillReport(
jasperReport, parameters, connection );

// export to pdf

JRPdfExporter exporter = new JRPdfExporter();

exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(
new SimpleOutputStreamExporterOutput("app_created_report.pdf"));

SimplePdfReportConfiguration reportConfig
= new SimplePdfReportConfiguration();
reportConfig.setSizePageToContent(true);
reportConfig.setForceLineBreakPolicy(false);

SimplePdfExporterConfiguration exportConfig
= new SimplePdfExporterConfiguration();
exportConfig.setMetadataAuthor("ANB");
exportConfig.setEncrypted(true);
exportConfig.setAllowedPermissionsHint("PRINTING");

System.out.println("set config!!! ...");
exporter.setConfiguration(reportConfig);
System.out.println("export config!!! ...");
exporter.setConfiguration(exportConfig);
System.out.println("exportReport!!! ...");
exporter.exportReport();
}


My gradle dependencies are :

// https://mvnrepository.com/artifact/net.sf.jasperreports/jasperreports
compile group: 'net.sf.jasperreports', name: 'jasperreports', version: '6.6.0'


Note:

I added this dependency to try to solve the issue but it didn't work, supposedly it have the missing class

// https://mvnrepository.com/artifact/com.itextpdf/itextpdf
compile group: 'com.itextpdf', name: 'itextpdf', version: '5.0.6'


The exception that I get is this one, it happens in the last line of the method shown above:

Important notice for the duplicate question claim:

I understand what is meant by ClassNotFoundException but I am asking why I am getting it in the jasper reports (since I am installing the dependency with Gradle which shall automatically get all needed dependencies & classes) so I am asking about this particular case which is not referenced in the claimed duplicate questions referenced

ClassNotFoundException

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

You can use code as follows:

// setting report parameters
HashMap parameters = new HashMap();

FileInputStream inputStream = new FileInputStream("/jasperReports/App_created_en.jrxml");
JasperDesign jasperDesign = JRXmlLoader.load(inputStream);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

// Pass compiled report to print
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReportMain, parameters, new JREmptyDataSource());
JasperViewer jasperViewer = new JasperViewer(jasperPrint);
jasperViewer.setVisible(true);
JasperExportManager.exportReportToPdfFile(jasperPrint, "app_created_report.pdf");
