struts2.StrutsTestCase.getActionProxy() NullPointerException

lychbeyond

我学做个例子：struts2.2.1+spring2.5+hibernate3.0+junit4
其中stuts.xml文件如下：
<constant name="struts.objectFactory" value="spring" />
<!-- Add packages here -->
<package name="default" namespace="/ut/regnlogin" extends="struts-default">
<action name="activateUserByEmail" class="activateUserByEmailBean">
<result>/ut/regnlogin/success.jsp</result>
<result name="error">/ut/regnlogin/error.jsp</result>
</action>

测试类如下：
public class ActivateUserByEmailTest extends StrutsTestCase{
@Test
public void testExecute() throws Exception {
  
  
  MockHttpServletRequest request = new MockHttpServletRequest();
  request.setParameter("id", "email1");

  ActionProxy proxy = getActionProxy("/ut/regnlogin/activateUserByEmail.action");
  assertNotNull(proxy);
  ActivateUserByEmail action = (ActivateUserByEmail) proxy.getAction();
  assertNotNull(action);
  String result;

   result = proxy.execute();

  assertEquals(Action.SUCCESS, result);
}
执行结果：
java.lang.NullPointerException   
        at org.apache.struts2.StrutsTestCase.getActionProxy(StrutsTestCase.java:130)

代码执行到
ActionProxy proxy = getActionProxy("/ut/regnlogin/activateUserByEmail.action");
显示空指针，是哪里的问题呀？
路径改成：.... getActionProxy("/ut/regnlogin/activateUserByEmail");
或getActionProxy("/activateUserByEmail.action");
或getActionProxy("/activateUserByEmail");
都还是空指针，是什么原因呢？

帮你顶一下，我也想知道结果
