Junit：創建BOFactory實例時出現異常

Question

我正在嘗試在IID8.5上設置JUnit框架。但是當我試圖運行簡單的JUnit測試用例時，我收到運行時錯誤。 （java.lang.NoClassDefFoundError：org.eclipse.core.runtime.RegistryFactory）

我正在使用JUnit4。 Please find attached image showing project structure

**Code in BOUtils.java **

package com.wf.utils; 
import com.ibm.websphere.bo.BOFactory; 
import com.ibm.websphere.sca.ServiceManager; 
import com.ibm.websphere.sca.Service.*; 

public class BOUtils { 

/** 
* @param args 
*/ 

public static void createBusinessObject() 
{ 
    System.out.println("Create Business Object"); 
    BOFactory boFactory = (BOFactory) new ServiceManager().locateService("com/ibm/websphere/bo/BOFactory"); 
} 
public static void main(String[] args) { 
    // TODO Auto-generated method stub 

} 

} 

**Code in JunitTest.java** 

package JunitTest; 
import junit.framework.TestCase; 
import com.wf.utils.BOUtils; 
import org.junit.Test; 


    public class JunitTest extends TestCase { 
    @Test 
    public void testPersistCust() 
    { 
    System.out.println("testPersistCust"); 
    BOUtils.createBusinessObject(); 
    } 
}

該異常告訴你，某個類是不可用的JVM你是內運行此。

簡單的回答：然後開始搜索那個類...並且你可以找到這個here - 你可以下載各種與eclipse相關的JAR。

因此：嘗試如果您將org-eclipse-equinox-registry.jar添加到您的類路徑中會發生什麼情況。

（這here可能包含是怎麼回事的解釋）
