Question

我已在我的项目上实施动态报告以生成pdf报告（版本4.0.0），但我收到了严重错误：

GRAVE：El Servlet.service（）para el servlet [com.pkg.svt_pdf] en el contexto con ruta [/ WEB]lanzólaexiverspción[LaejecucióndelServletlanzóunaaexpción] concausaraíz java.lang.NoSuchMethodError：com.itextpdf.text.Document.setRole（Lcom / itextpdf / text / pdf / PdfName;）V at net.sf.jasperreports.engine.export.JRPdfExporter.exportReportToStream（JRPdfExporter.java:580） at net.sf.jasperreports.engine.export.JRPdfExporter.exportReport（JRPdfExporter.java:519） at net.sf.dynamicreports.jasper.builder.JasperReportBuilder.export（JasperReportBuilder.java:630） at net.sf.dynamicreports.jasper.builder.JasperReportBuilder.toPdf（JasperReportBuilder.java:532）在com.pkg.reports.ReportsGenerator.exportPDF（ReportsGenerator.java:73）在com.pkg.svt_pdf.doGet（svt_pdf.java:53）在javax.servlet.http.HttpServlet.service（HttpServlet.java:620）在javax.servlet.http.HttpServlet.service（HttpServlet.java:727）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:303）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:208）在org.apache.tomcat.websocket.server.WsFilter.doFilter（WsFilter.java:52）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:241）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:208）在org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:220）在org.apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:122）在org.apache.catalina.authenticator.AuthenticatorBase.invoke（AuthenticatorBase.java:501） at org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:171）在org.apache.catalina.valves.ErrorReportValve.invoke（ErrorReportValve.java:103）在org.apache.catalina.valves.AccessLogValve.invoke（AccessLogValve.java:950）在org.apache.catalina.core.StandardEngineValve.invoke（StandardEngineValve.java:116）在org.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:408）在org.apache.coyote.http11.AbstractHttp11Processor.process（AbstractHttp11Processor.java:1070） at org.apache.coyote.AbstractProtocol $ AbstractConnectionHandler.process（AbstractProtocol.java:611）在org.apache.tomcat.util.net.AprEndpoint $ SocketProcessor.doRun（AprEndpoint.java:2440）在org.apache.tomcat.util.net.AprEndpoint $ SocketProcessor.run（AprEndpoint.java:2429）在java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1145） at java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:615） at org.apache.tomcat.util.threads.TaskThread $ WrappingRunnable.run（TaskThread.java:61）在java.lang.Thread.run（Thread.java:745）

这是我的代码：

  AbstractJasperExporterBuilder exporter = export.pdfExporter(output);
    exporter.setCharacterEncoding("UTF-8");
    JasperReportBuilder jrb = JRBuild(connection);
    jrb.toPdf((JasperPdfExporterBuilder) exporter);

此行中的错误：

jrb.toPdf((JasperPdfExporterBuilder) exporter);
