Question

我已经在JSP页面中配置了编译Jasper Report。我已完成连接数据库的工作，收集了JRXML文件以及报告的参数，如下所示：

JasperDesign jasperDesign = JRXmlLoader.load(reportFile);
jasperDesign.setLanguage(language);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, jasperParameter, jdbcConnection); //line4

在生成报告时，我在line 4中遇到错误。

我得到的是：

也说

java.lang.NoClassDefFoundError: Could not initialize class net.sf.jasperreports.engine.util.JRStyledTextParser

为您简要介绍一下我所做的是：

赋予启动属性 -Djava.awt.headless = true。
授予对jrxml文件以及相关的JARS的完全访问权限
检查Tomcat中是否存在临时文件夹。
尝试重新启动Tomcat /服务器。

可用的JARS列表如下：

jasper-compiler-jdt-5.5.23
jasperreports-5.1.0
jasperreports-chart-themes-4.5.0
jasperreports-core-renderer
jasperreports-extensions-3.5.3
jasperreports-fonts-4.5.0
jasperreports-htmlcomponent-4.1.1
jasperreports-jtidy-r938

期待解决方案。在此先感谢！
