Java Web Start가 작동하지 않습니다.

Question

Java 프로젝트에서 작업했습니다. 이제 끝났지 만 Java Web Start가 작동하지 않습니다. 프로그램을 컴파일하고 dist 파일을 Tomcat 서버에 넣습니다. 고객이 내 프로그램을 다운로드하고 데스크톱 응용 프로그램으로 사용하기를 원합니다.

Netbeans IDE에서 프로그램을 실행할 수 있지만 .jnlp 파일을 사용해 보면 오류가 발생합니다. 얼마 전까지 만해도 jnlp를 사용하여 프로그램을 실행할 수 있었지만 여하튼 오류가 발생했습니다. 실행 가능한 jar로 프로그램을 실행할 수는 있지만 Java Web Start를 필사적으로 사용해야합니다.

Answer 1

오류가 지적하므로 사용 권한에 문제가 있습니다.
는 (: java.security.AccessControlException :에 의한 액세스 ("java.util.PropertyPermission에" "하여 file.encoding" "읽기")를 거부)

는 또한, 당신은 보안 귀하의 JNLP에 태그 지정 누락 :

Answer 2

기본적으로 Java 웹 시작 응용 프로그램은 애플릿과 같은 샌드 박스에서 실행됩니다. 이 오류는 file.encoding 시스템 속성을 읽을 수있는 권한이 없음으로 인한 것 같습니다. jnlp에 애플리케이션에 필요한 권한 수준을 정의해야합니다. 다음 요소를 추가하면 권한 문제가 해결됩니다.

<security> 
    <all-permissions/>
