java - ireport4 java.lang.ClassNotFoundException : org. apache.batik.svggen.SVGGraphics2DIOException

Question

我正在使用时间序列图表。效果很好。但是，当我在JAVA中使用它时，出现了一些异常。

  JasperPrint jasperPrint = JasperFillManager.fillReport(jasperPrintFile.getPath(), paraMap, DBUtil.getConnection());

我在这里列出了所有堆栈跟踪。谁知道这个问题的根本原因是什么？非常感谢。

Answer 1

Jasper Reports 项目文件夹 (jasperreports-x.x.x-project.zip) 的 /lib 中缺少 jar 文件 batik-svggen.jar。

对于ClassNotFoundException或NoSuchMethodException，通过http://www.findjar.com/检查相关类或方法
