無法使用JUNIT和OPENJPA連接到數據庫

Question

使用我的JUNIT代碼連接到Oracle數據庫時，我面臨一個問題（默認情況下它會嘗試連接到HSQL）。我使用openjpa作爲持久性提供者。我已經嘗試了很多方法，包括在persistence.xml中指定連接設置並在Test class中指定連接設置。

public class CollateralHandlerTest { 

    private static InitialContext ctx; 

    @BeforeClass 
    public static void initContainer() throws Exception { 
     final Properties props = new Properties(); 
     props.put("tomee.ejbcontainer.http.port", 1800); 
     props.put(Context.INITIAL_CONTEXT_FACTORY,"org.apache.openejb.client.LocalInitialContextFactory"); 
     props.put("ProvAppCLJPA.openjpa.ConnectionURL", "jdbc:oracle:thin:@localhost:1521:XE"); 
     props.put("ProvAppCLJPA.openjpa.ConnectionPassword", "XXXX"); 
     props.put("ProvAppCLJPA.openjpa.ConnectionDriverName", "oracle.jdbc.OracleDriver"); 
     props.put("ProvAppCLJPA.openjpa.ConnectionUserName", "PROVAPPCL_DE"); 
     ctx = new InitialContext(props); 

    } 

    @Test 
    public void testCollateralHandler() throws NamingException, ProvAppException { 
     Object object = ctx.lookup("CollateralHandlerLocal"); 
     assertTrue(object instanceof ICollateralHandler); 
     ICollateralHandler collHandler = (ICollateralHandler) ctx.lookup("CollateralHandlerLocal"); 
     List<Customer> cust = collHandler.getAllCollateral("XXXX"); 
    } 
} 

我而在「getAllCollat​​eral」功能執行

final Query query = entityManager.createNamedQuery(""); 
    query.getResultList(); 

獲得在測試方法的最後一行的錯誤。

我得到下面的異常

不知它試圖拿起HSQL數據庫作爲數據庫，我不知道爲什麼它不拿起神諭設置。 我還通過以下網址

http://openjpa.apache.org/testing.html

了，並試圖以設置VM參數連接屬性。 請幫忙!!!

我知道它通過以下配置工作。雖然我仍然不知道爲什麼它不適用於openjpa設置。

protected void setUp() throws Exception 
    { 
     final Properties props = new Properties(); 
     props.put("tomee.ejbcontainer.http.port", 1800); 
     props.put(Context.INITIAL_CONTEXT_FACTORY,"org.apache.openejb.client.LocalInitialContextFactory"); 
     props.put("ProvAppCLJPA", "new://Resource?type=DataSource"); 
     props.put("ProvAppCLJPA.JdbcUrl", "jdbc:oracle:thin:@localhost:1521:XE"); 
     props.put("ProvAppCLJPA.Password", "XXX"); 
     props.put("ProvAppCLJPA.JdbcDriver", "oracle.jdbc.OracleDriver"); 
     props.put("ProvAppCLJPA.UserName", "PROVAPPCL_DE"); 
     props.put("ProvAppCLJPA.JtaManaged", "true"); 

     ctx = new InitialContext(props); 
    }
