Я использую Struts2, Spring3 для своего приложения, когда я выполняю тест jUnit4 для своего приложения, я получаю эту ошибку:
null java.lang.NullPointerException
at org.apache.struts2.StrutsJUnit4TestCase.executeAction(StrutsJUnit4TestCase.java:134)

ошибка возникает, когда я вызываю метод executeAction. Как решить эту проблему.
