seam-2.2.2 java 8 drools update

Question

Java 8 환경에서 seam-2.2.2 응용 프로그램을 컴파일하고 실행해야합니다. 이음새 신원 관리를 제외한 모든 것이 잘 작동합니다. 이것은 Drools와 관련이있는 것 같습니다. 2.2.2

자바 8 환경에서 이음새 응용 프로그램을 실행할 때 다음 예외가 발생합니다. org.jboss.seam.InstantiationException : Seam 구성 요소를 인스턴스화 할 수 없습니다. org.jboss .seam.security.ruleBasedPermissionResolver

응용 프로그램을 구성하는 drools을 제외하고 더 이상 예외는 없습니다. 솔기 응용 프로그램이 올바르게 작동하고 있습니다. java 5 환경에서는 예외가 발생하지 않습니다.

이 문제를 해결하는 방법은 무엇입니까?

Answer 1

여기 일어나고 솔기 (및 응용 프로그램)에서 일부 자바 코드는 자바 (8) 컴파일러를 사용하여 컴파일 된 것입니다 무슨 생각합니다. 그런 다음 org.drools.compiler.PackageBuilder이 호출되어 일부 DRL을 컴파일합니다. 그러면 결국 Java 컴파일러를 호출하여 DRL에서 생성 된 Java 코드를 컴파일합니다. 이를 위해 Java 컴파일러는 Eclipse를 통해 호출되며 Java 8에서 컴파일 한 클래스를 가져올 때이 컴파일러는 만족스럽지 않습니다.

따라서이 문제를 해결하는 것이 좋습니다. Eclipse 및 Java 설치.

Drools에서 Java 컴파일러를 사용하도록 구성하는 방법이 있지만 일반적으로 Eclipse를 통해 기본값을 사용하면 잘 작동합니다.
