我正在使用Java开发软件。

我将JasperReports与用于账单打印的条码访问链接。

我的问题是，当我尝试打印该报告时，发生了此异常：

net.sf.jasperreports.engine.JRRuntimeException: java.io.IOException: SAX2 driver class org.apache.crimson.parser.XMLReaderImpl not found

我怎么解决这个问题？

您的应用程序没有找到所需的库。据我所知，您需要下载Apache 的 Crimson XML Parser并将其添加到应用程序的类路径中。

看起来该库不在您的类路径中

如果您在命令行上运行

  1. 更新清单以将 jar 包含在其类路径中

  2. 在您的行中手动包含使用“-cp”以添加更多同学条目。例如 java -co jar1.jar;jar2.jar -jar my.jar 这假定 Windows 作为分隔符是 ;
