Hibernate 4+ Spring 4 : can't load my Config File with ClassPathXmlApplicationContext,

i'm working on a maven project with spring-framework and hibernate. I have these two method:

 public void loadXml() throws IOException, URISyntaxException {
    String filePathXml ="spring_hibernate_files/spring-hibernate4.xml";
    File file = Resources.getResourceFile(filePathXml);
    if(file.exists()){
        ApplicationContext contextClassPath = new ClassPathXmlApplicationContext(file.getAbsolutePath());
    }
}
public static File getResourceFile(String name){
        return new   File(Resources.class.getClassLoader().getResource(name).getFile());
}

This is the spring-hibernate4.xml, located in resources/spring_hibernate_files/spring-hibernate4.xml

When i arrived to run the line of code:

ApplicationContext contextClassPath = new ClassPathXmlApplicationContext(file.getAbsolutePath());

(NOTE:I've tried with all kind of analog string for match the file), I have the following exception, i've tried and search on the web with similar problema but now i'm stuck. This is the exception:
