Question

我正在尝试使用 JasperReports 生成 PDF 。

我第一次尝试时，出现此错误：

ERROR [net.sf.jasperreports.extensions.DefaultExtensionsRegistry] Error instantiating extensions registry for chart.theme

但是，生成 PDF 没有任何问题。

另外，下次我尝试生成一个 PDF 时，不再有错误。这只发生在第一代。

是什么原因？我怎么能避免这个错误？

Answer 1

确定问题已解决。

我在我的类路径中包含了jasperreports-chart-themes-4.7.0.jar。但是，这个罐子不再使用了。我只使用了jasper中的默认主题。

从.ear中删除此jar，一切正常。

非常感谢
