我正在开发一个maven spring-mvc应用程序并尝试使用jasper生成报告。 以下代码在我使用jetty ：
的测试环境中启动时效果很好 JasperReportBuilder report = DynamicReports.report();//a new report]
StyleBuilder boldStyle = stl.style().bold();
StyleBuilder boldCenteredStyle = stl.style(boldStyle).setHorizontalAlignment(HorizontalAlignment.CENTER);
StyleBuilder columnTitleStyle = stl.style(boldCenteredStyle).setBorder(stl.pen1Point()).setBackgroundColor(Color.LIGHT_GRAY);
report.setColumnTitleStyle(columnTitleStyle).columns(
Columns.column("currency", "currency", DataTypes.stringType()),
Columns.column("abbrevia", "abbrevia", DataTypes.stringType()),
Columns.column("id", "id", DataTypes.integerType()));
report.title(Components.text("Transaction Reports").setHorizontalAlignment(HorizontalAlignment.CENTER))
.pageFooter(Components.pageXofY())//show page number on the page footer
.setDataSource(currenciesService.findAll());
System.out.println("evo ga " + currenciesService.findAll());
try {
report.show(false);
JFrame frame = new JFrame("Report");
frame.getContentPane().add(new JRViewer(report.toJasperPrint()));
frame.pack();
frame.setSize(400, 600);
frame.setVisible(true);
然而，当我将.war文件上传到glassfish时，它并没有做到这一点。
以下是我从glassfish服务器获取的错误消息：

我测试了查询和数据库连接，传递得很好。我也正确地在我的pom.xml中添加了依赖项。那么是什么导致了我的问题？
