OpenJPA Webspere 7 Log4j 구성

Question

남자 나는 이것으로 고민하고있다. 내가 systemout에서 로깅을 리디렉션하려고합니다. 위의 파일 : 성공하지와의 log4j rollingappender 파일 는 아래 내가 최대한 빨리이 추가로 다음과 같은 오류가 내 persistent.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
    http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0"> 
    <persistence-unit name="R_TEST" transaction-type="RESOURCE_LOCAL"> 
     <provider> 
    com.ibm.websphere.persistence.PersistenceProviderImpl 
     </provider> 
     <non-jta-data-source>jdbc/TESTDB</non-jta-data-source> 
     <class>com.ra.WSProcess</class> 
    <property name="openjpa.jdbc.Schema" value="TEST" /> 
      <property name="openjpa.Log" value="log4j"/>  
     </properties> 
    </persistence-unit> 

의 샘플입니다. 나는이 두 파일 (commons-logging-1.1.jar, log4j-1.2.6.jar)을 WEB_INF/lib에 복사하려고 시도했지만 문제가 없었다. 웹에서이 작업을 수행하는 방법에 대한 정보가 부족한 것 같습니다. 어떤 아이디어?

Answer 1

log4j의 openjpa.Log 속성 값이 작동하지 않을 수 있습니다 작업에서 내 응용 프로그램을 중지하는 것처럼 내가 웹 스피어에서 클래스 로딩 정책을 변경할 수 있습니다 내장 된 IBM PersistenceProviderImpl 내장 때문에 JPA 프로 바이더에는, 어플리케이션 JAR에 대한 클래스 로더 가시성이 없기 때문에, 클래스 로더 설정 옵션은 그 작업을 실시 할 수 없습니다. 유일한 옵션은 OpenJPA와 configure it as a third-party persistence provider을 다운로드하는 것입니다.
