Spring / Log4j

Quando eu tento executar o código a seguir:

public static void main(String[] args) {
		SetorDAO setorDAO;
	
		ApplicationContext context = new ClassPathXmlApplicationContext("ApplicationContext.xml");
		setorDAO = (SetorDAO) context.getBean("setorDAO");
		
		SetorVO setor = new SetorVO();
		setor.setDescricao("DTI - Departamento de Tecnologia da Informação");
		
		setorDAO.incluir(setor);
	}

Ocorre o seguinte erro

Exception in thread "main" java.lang.ExceptionInInitializerError at org.springframework.core.io.DefaultResourceLoader.<init>(DefaultResourceLoader.java:52) at org.springframework.context.support.AbstractApplicationContext.<init>(AbstractApplicationContext.java:181) at org.springframework.context.support.AbstractRefreshableApplicationContext.<init>(AbstractRefreshableApplicationContext.java:80) at org.springframework.context.support.AbstractXmlApplicationContext.<init>(AbstractXmlApplicationContext.java:58) at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:89) at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:75) at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:65) at br.gov.mt.mp.ci.dao.Teste.main(Teste.java:16) Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException) (Caused by org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException)) at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:543) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:235) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:209) at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:351) at org.springframework.util.ClassUtils.<clinit>(ClassUtils.java:67)
