Question

我有一个项目，其中jasper报告是从java方法创建的。我的碧玉代码如下：

<?xml version="1.0" encoding="UTF-8"?>

问题是在运行时我得到以下错误：无法创建报告流org.xml.sax.SAXParseException; lineNumber：26; columnNumber：30;第26行char 30处的错误：net.sf.jasperreports.engine.design.JRDesignComponentElement无法强制转换为net.sf.jasperreports.engine.JRBoxContainer。请帮我解决这个问题并提前感谢..

Answer 1

当我将jar-“jasperreports”从“3.1.2升级到3.7.2”时，上述问题已经解决了。此外，我已将itext.jar升级到2.1.5并将poi.jar升级到3.5 FINAL以修复字体问题和pdf导出问题。我希望它适用于所有人..
