위 코드는 web-apps/report 폴더 use.jasper에서 사용합니다.

Error 500: Executing action [index] of controller [org.codehaus.groovy.grails.plugins.jasper.JasperController] in plugin [jasper] caused exception: null 
Servlet: grails

Exception Message: invalid stream header: 3C3F786D 
Caused by: invalid stream header: 3C3F786D

하지만 잘못된 스트림 헤더 인 3C3F786D가 잘못 표시됩니다. 이 문제를 해결하려면 안내해주세요.

.jrxml 파일을 사용하여 하위 보고서를 참조하는 것 같습니다. 그러나 컴파일 된 버전 인 .jasper를 사용해야합니다.

나는 그 작품 희망!
