발생 원인 : java.lang.ClassCastException 래퍼를 캐스팅 할 수 없습니다.

Javafax 2.2 클라이언트가있는 glassfish 3.1 컨테이너에서 실행되는 원격 EJB를 실행하려고하는데 원격 EJB를 "조회"할 때 예외가 발생합니다. 내 응용 프로그램의 목적은 서버 측에서 XML 파일로 저장/검색하는 Javafx Client 객체를 가져 오거나 가져 오는 것입니다.발생 원인 : java.lang.ClassCastException 래퍼를 캐스팅 할 수 없습니다.

서버 측에서은 EJB가 EAR에 패키지되어 있습니다.

나는 다른 이름으로 시도하는 경우 :

이

SessionRemote mySession = (SessionRemote)ctx.lookup("java:global/Scrubber_S_EAR/Scrubber_S/Session!scrubber_S_Controller.SessionRemote");

그것은 같은 exeption를 발생시킵니다.

누군가가 내가이 문제를 해결하도록 도울 수 있다면 좋을 것입니다.

도움을 주셔서 미리 감사드립니다.

나는 영어가 이해하기 너무 나쁘지 않기를 바랍니다.

나는 다음과 같이이 문제를 해결 :

는 ENV에서 jar 파일을 제거하고 만 GF-클라이언트를 넣어.클래스 패스에 항아리로
How do I access a Remote EJB component from a stand-alone java client?
이름 바꾸기에 "scrubber_S_Controler을"설명 (클라이언트 측에서 해당 패키지와) "세션"에
제거 "retrieveSimpleObject()"와 "saveSimpleObject (SimpleObject simpleobjet) ""SimpleObject "클래스에서"SimpleObjectPersist 클래스 "에 추가하십시오.
"SimpleObjectPersist "를 사용하여 SimpleObject를 저장하고 검색하십시오.

우우! 그 후, 잘 실행 중입니다.
