Spring MVC 2.5 load property PropertiesFactoryBean return null
===

I want to load a properties in my project with:
	
    <bean id="properties_es"
		class="org.springframework.beans.factory.config.PropertiesFactoryBean">
		<property name="location" value="classpath:/texts/report_es.properties" />
    </bean>
    <bean id="properties_en"
		class="org.springframework.beans.factory.config.PropertiesFactoryBean">
		<property name="location" value="classpath:/texts/report_en.properties" />
    </bean>

And then I try to get both .properties


    public class PropertiesManager {
        public static enum LanguageEnum{es, en}
    
        @Autowired
        private java.util.Properties properties_es;
        @Autowired
        private java.util.Properties properties_en;
    
        public String getProperty(LanguageEnum language, String key) {
	        switch (language) {
	        case es:
	            return properties_es.getProperty(key);
	        case en:
	            return properties_en.getProperty(key);
	        default:
	            return properties_en.getProperty(key);
            }
        }
    }

But properties_es is null, and properties_en is null too
