javax.net.ssl.HttpsURLConnection을 사용하여 URL에 연결하는 중 "java.lang.ClassCastException"이 표시됩니다.weblogic.net.http.SOAPHttpsURLConnection을 javax.net.ssl.HttpsURLConnection에 캐스팅 할 수 없습니다.
나는 웹 로직 서버 10.3.4를 사용하고 있습니다.

내가 점점 오전 예외는 다음과 같습니다
**java.lang.ClassCastException: weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection

이 오류를 얻기의 모든 가능한 이유?
캐스팅 후에 'instanceof'테스트 *를 수행하는 데 많은 포인트가 없으며 사용하지 않는 클래스에 캐스팅 할 때 아무런 의미가 없습니다. URLConnection으로 사용하십시오. – EJP
'instanceof'는 테스트 목적으로 만 사용되었습니다. HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); 다음 줄에서 캐스팅 오류가 발생합니다. – KmrGtm
코드 fine..here를 실행하면 출력에게 있습니다 http://sebsauvage.net/paste/?987346d13f71f550#800M7Vwk73Y5OOPpLhwIleZdktYk+vf0VAZKOtOoqfw= –
