java - birt エンジンでのレポート生成中の FontHandler 例外

Question

バートレポートの生成中に例外を下回っています。スタックトレース付きのコードの下に示します。

アプリケーションに他のフォント関連ファイルを追加する必要がありますか? 誰もこれについて考えを持っていますか。

「HTML」としてレンダリングオプションがある場合、正常に機能しています。「pdf」としてレンダリングオプションがある場合にのみ、以下の例外をスローします。

BirtEngineDesktop.java: java.io.File をインポートします。java.io.FileInputStream をインポートします。java.util.HashMap をインポートします。import java.util.logging.Level; import org.eclipse.birt.core.exception.BirtException; org.eclipse.birt.core.framework.Platform をインポートします。import org.eclipse.birt.report.engine.api.*;

public class BirtEngineDesktop {

public static void main(String[] args) throws Exception {
    String reportName = "new_report_2.rptdesign";
    IReportEngine engine = null;
    IReportRunnable design = null;
    IRunAndRenderTask task = null;
    PDFRenderOption renderContext = null;
    HashMap contextMap = null;
    PDFRenderOption options = null;
    final EngineConfig conf = new EngineConfig();
    conf.setEngineHome("ReportEngine");
    System.out.println("BIRT_HOME: " + conf.getBIRTHome());
    conf.setLogConfig(null, Level.FINE);

    try {
        Platform.startup(conf);
    } catch (BirtException e1) {
        e1.printStackTrace();
    }

    IReportEngineFactory factory = (IReportEngineFactory) Platform
            .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
    engine = factory.createReportEngine(conf);

    try {
        design = engine.openReportDesign(reportName); 
    } catch (Exception e) {
        System.err.println("An error occured during the opening of the report file!");
        e.printStackTrace();
        System.exit(-1);
    }
    task = engine.createRunAndRenderTask(design);
    renderContext = new PDFRenderOption();
    contextMap = new HashMap();
    FileInputStream fis = new FileInputStream(new File("C:\\test\\sample.xml"));
    contextMap.put("org.eclipse.datatools.enablement.oda.xml.inputStream",fis);     
    contextMap.put(EngineConstants.APPCONTEXT_PDF_RENDER_CONTEXT,
            renderContext);
    task.setAppContext(contextMap);


    options = new PDFRenderOption();
    options.setOutputFileName("D://"+reportName + ".pdf");         options.setOutputFormat("pdf");
    task.setRenderOption(options);
    try {
        task.run();
    } catch (Exception e) {
        e.printStackTrace();
        System.exit(-1);
    }
   engine.destroy();
    System.exit(0);
} }

そして私のスタックトレースは次のとおりです。
