java - 朱尼特 : Exception while creating BOFactory instance

Question

我正在尝试在 IID8.5 上设置 JUnit 框架。但是当我尝试运行简单的 JUnit 测试用例时，我收到运行时错误。 (java.lang.NoClassDefFoundError: org.eclipse.core.runtime.RegistryFactory)

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

**BOUtils.java 中的代码**

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();
  }
}

该异常告诉您某个类对于您正在其中运行的 JVM 不可用。

简单的答案:然后开始搜索该类......你可以找到这个 here - 您可以在其中下载各种与 eclipse 相关的 JAR。

因此:尝试一下如果将 org-eclipse-equinox-registry.jar 添加到类路径中会发生什么情况。

(此 here 可能包含对正在发生的事情的解释)
