Jasper 报告未在 ADF 的屏幕上呈现 PDF 文件

Question

我收到错误消息：Error While Displaying Report Page : See Console for Details

我有以下所有罐子

• iText-2.1.7.js2
• jackson-core-2.1.4
• jasperreports-5.6.0
• jasperreports-chart-themes-5.6.0
• jasperreports-core-renderer
• jasperreports-fonts-5.6.0
• jcommon-1.0.15
• jfreechart-1.0.13

谁能告诉我哪里错了？

我缺少任何罐子吗？

我们已经在 adf 中渲染了相当多的 pdf。这是一个这样的例子。附上所需的罐子清单以供参考。 我的 jasper 报告 (MainReport.jasper) 捆绑在一个 jar 文件中并放入应用程序中。
