요약하면 WebSphere에 응용 프로그램의 el-api.jar에서 클래스를 사용하도록 지시하는 방법이 있습니까? 대신 (내장 된) javax.j2ee.el.jar에서?WebSphere 8 : el-api.jar (in app)이 javax.j2ee.el.jar (WS)와 충돌 함
이야기 : 8 개 시도 될 때 모든 일이 걸리면
: 내가 거기에 8 WAS에 WAS 6.1에서 마이그레이션하는 응용 프로그램을하는 동안이 문제에 대한 인터넷에 대한 논의가 있지만 그 중 어느 것도 명시 적으로이 점을 언급 알고 el-api.jar (EAR에 포함)에서 javax.el.ExpressionFactory를로드합니다. 그러나이 시점에서 이미 javax.j2ee.el.jar에서로드했습니다. (WAS 6.1에는 존재하지 않았다.) 자세한 클래스 로딩을 스위치 온하면 :
클래스로드 : javax.el.ExpressionFactory from : file :/C :/Program Files/
el-api.jar가 들어있는 응용 프로그램의 EAR을 설치하기 전에이 jar 파일이 이미로드되어 있기 때문에 보이는 것 같습니다. WAS 8 (응용 프로그램을 설치하기 전에) PARENT_LAST 클래스 로딩 전략을 사용하도록 지정했는지 여부에 관계없이 클래스 로딩 충돌시 발생합니다.
el-api.jar 대신 javax.j2ee.el.jar를 사용하여 응용 프로그램을 컴파일하고 설치할 수는 있지만, 한편으로는 이것이 장기적으로 어떤 결과를 낳을 지 모릅니다. 나는 지금까지 어떤 식 으로든 실행시킬 수 없었습니다.) 한편, 궁극적 인 목표는 WAS 8 서버에 원래의 EAR (자체 JSF 라이브러리 등 포함)을 설치할 수있게하는 것이 었습니다 가능하면 수정.
WAS 8 서버가 el-api.jar에서 충돌하는 클래스를 다시로드하거나 처음에 javax.j2ee.el.jar을로드하지 않도록 말할 수있는 방법이 있습니까? (앞에서 언급 한 것처럼 PARENT_CLASS를 지정해도 영향이 없습니다.)
감사합니다.
(설치된 응용 프로그램을 시작할 때) 엘-api.jar을에서 javax.el.ExpressionFactory를로드 8 개 시도 할 때 발생합니다 그런데 예외 :
