[java] 인식 할 수없는 SSL 메시지, 일반 텍스트 연결? 예외

net에서 https 서버와 통신하기 위해 Java 호환 패키지가 있습니다. 컴파일을 실행하면 다음 예외가 발생합니다.

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

at com.sun.net.ssl.internal.ssl.InputRecord.read(Unknown Source)

at sun.net.www.protocol.https.HttpsURLConnectionImpl.connect(Unknown Source)

클라이언트 컴퓨터와의 연결이 안전하지 않기 때문입니다. 원격 https 서버에 연결하기 위해 로컬 시스템을 구성 할 수있는 방법이 있습니까?
