ejb 프로젝트에서 drl 리소스를 찾을 수 없습니다.

Question

optaplanner (6.0.1)를 사용하는 엔터프라이즈 애플리케이션 (Glassfish 4)을 만들고 있습니다. 솔버는 EJB 프로젝트 내에서 시작됩니다. 방금 찾은 XML 구성을로드 할 수 있지만 솔버를 빌드하는 drl을 찾지 못합니다.

SolverFactory solverFactory = new XmlSolverFactory().configure(PropositionSB.class.getResourceAsStream("/resources/todoSolverConfig.xml")); 
Solver solver = solverFactory.buildSolver(); 

는

Caused by: java.lang.IllegalArgumentException: The scoreDrl (/resources/todoScoreRules.drl) does not exist as a classpath resource.

내가 비록 간단한 Java 응용 프로그램에서 작업 할 때이 같은 문제를 가지고 있겠지 발생합니다.

Answer 1

은 앱 서버에서 다음을 시도해보십시오

// OptaPlanner 6.0 
URL r = SolverFactory.class.getResource("/resources/todoScoreRules.drl"); 
System.out.println("Resource found: " + (r == null)); 

// OptaPlanner 6.1+ 
URL r = SolverFactory.class.getClassLoader().getResource("resources/todoScoreRules.drl"); 
System.out.println("Resource found: " + (r == null)); 

그런 다음 자신의 getClass()와 SolverFactory.class를 교체하려고합니다.
