OpenJPA Webspere 7 Log4j配置

Question

夥計們我正在努力與這一個。我正試圖從systemout重定向日誌記錄。 與沒有成功的log4j rollingappender文件，下面是我的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> 

的樣品我，只要我添加此出現以下錯誤：上面的文件。我試圖將這兩個文件（commons-logging-1.1.jar，log4j-1.2.6.jar）複製到WEB_INF/lib中，但沒有解決問題。似乎沒有太多的網絡上如何讓這個工作。有任何想法嗎 ？

請注意，我不能改變WebSphere中的類裝入政策，因爲這會從工作

Answer 1

的log4j的openjpa.Log屬性值不能一起工作停止我的應用程序內置在IBM PersistenceProviderImpl因爲內置在JPA提供程序中，您的應用程序JAR沒有類加載器可見性，並且沒有類加載器配置選項可使其工作。唯一的選擇是自己下載OpenJPA和configure it as a third-party persistence provider。
