我正在使用java swings和jasper报告进行最后一年的项目报告。当我在netbeans中运行应用程序但是当我将它部署到jar文件然后尝试执行它时,包括报告的应用程序工作正常使用我的命令提示符,我看到了这个异常的大文本。
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/codehaus/groovy/control/CompilationFailedException at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Unknown Source) at java.lang.Class.getConstructor0(Unknown Source) at java.lang.Class.newInstance0(Unknown Source) at java.lang.Class.newInstance(Unknown Source) at net.sf.jasperreports.engine.JasperCompileManager.getCompiler(JasperCompileManager.java:472) at net.sf.jasperreports.engine.JasperCompileManager.loadEvaluator(JasperCompileManager.java:238) at net.sf.jasperreports.engine.fill.JRFillDataset.createCalculator(JRFillDataset.java:421) at net.sf.jasperreports.engine.fill.JRBaseFiller.(JRBaseFiller.java:428) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:76) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:86) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:56) at net.sf.jasperreports.engine.fill.JRFiller.createFiller(JRFiller.java:142) . . . . ....54 more
以下函数调用jasper报告:
public void printReport(String adID){ try { Map parameters = new HashMap(); InputStream jasperIS =this.getClass().getResourceAsStream("/Reports/AllHoardings.jasper"); User connect=new User(); JasperPrint print=JasperFillManager.fillReport(jasperIS,parameters,connect.getConnection()); JasperViewer.viewReport(print,false); }catch(JRException je){ System.out.println(je.toString() +" @ line 2043"); }catch (Exception e) { System.out.println(e.toString()); } }

java.lang.NoClassDefFoundError: org/codehaus/groovy/control/CompilationFailedException
这个错误告诉我,NetBeans正在以一种你的JAR文件没有的方式解决Groovy和Jasper Reports的问题。检查JAR清单中是否缺少与Groovy相关的JAR。如果是,请添加它们。
