Frühling JUnit-Test Nullpointer auf retrieveContextLoaderClass

Question

ich einen sehr einfachen JUnit-Test habe:

import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 
@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration({"file:C:\\Tools\\apache-tomcat-6.0.32\\webapps\\cyrus\\WEB-INF\\applicationContext-test.xml"}) 
public class CostEngineTest { 
    @Test 
    public void test(){ 
    } 
} 

und ein einfaches application:

<?xml version="1.0" encoding="UTF-8"?> 

<beans xmlns="http://www.springframework.org/schema/beans" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 

    <bean id="test" class="com.test.CommonCostEngine"> 
    </bean> 


</beans> 

Halten Sie diesen Fehler:

Irgendwelche Ideen ?

Das einzige Problem, das ich sehe, ist der XML-Namespace. Es sollte

sein

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation=" 
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
