以下函数调用jasper报告：

The following function invokes the jasper report :

    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());       }
    }

推荐答案

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。

This error suggests to me that NetBeans is solving your issues with Groovy and Jasper Reports in a way that your JAR file is not. Check to see if there are JARs missing from your JAR manifest that pertain to Groovy. If yes, add them.
