로마 사용 OSGI/Adobe AEM

Question

RSS 피드 생성을 위해 로마 도서관을 사용하여 문제가 발생했습니다. https://rometools.github.io/ lib를 pom.xml에 추가하고 AEM 인스턴스에 배포하고 라이브러리를 사용해야하는 서블릿을 호출하면 실패합니다. Iam이 서블릿으로 디버그 할 수 없습니다.

나는 이것이 클래스 로딩 문제이며, rome 도구의 웹 사이트에서 시스템 속성 'rome.pluginmanager.useloadclass'를 true로 설정하는 힌트라고 생각합니다. 이것을 어떻게 할 수 있습니까? 시작 매개 변수로 또는 내부 아파치 펠릭스 콘솔이나 AEM 내의 다른 장소에서 할 수있는 방법이 있습니까? 오류 로그에서

내가 다음과 같은 메시지를 받았습니다 :

해결책 :

당신의 pom.xml

<Embed-Dependency> 
       rome, 
       rome-utils, 
       jdom2 
</Embed-Dependency> 

Answer 1

솔루션에 포함 된 종속에 또한 로마 libs와 추가 :

로마 libs도 pom.xml의 포함 된 종속성에 추가하십시오.
