Equinox osgi와 commons.fileupload를 사용하는 중에 ClassNotFoundException : org.apache.commons.io.output.DeferredFileOutputStream 오류가 발생했습니다.

Question

파일을 입력으로 사용해야하는 웹 플러그인을 구현하려고합니다. 그래서 org.apache.commons.fileupload를 사용하고 있습니다. 그것은 org.apache.commons.io에 대한 내부 의존성을 가지고 있기 때문에 Bridge뿐 아니라 내 플러그인에도 포함되어 있습니다. 하지만 런타임에 다음과 같은 오류가 발생하고 있습니다.

SEVERE: Servlet.service() for servlet [equinoxbridgeservlet] in context with path [/bridge]  threw exception [Servlet execution threw an exception] with root cause

Answer 1

나는 거의 모든 것을 올바르게했다. 하지만 나는 수입 패키지에 대한 의존성을 MANIFEST.MF 파일에 추가하는 것을 잊지 않습니다. 종속성에 org.apache.commons.io.output을 추가하면됩니다. 그것은 작동합니다 :)
