Can't load beans XSD in Eclipse - SAXParseException

I'd like to run a simple Hello World programme in Eclipse (using Maven and Spring integrations). In the beans.xml I have this:

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

<bean id="person" class="spring.tutorial.Person"></bean>
</beans>


In the App.java I use ApplicationContext to instanciate the person bean. Unfortunately, I got this error:

szept. 01, 2016 1:12:05 DU org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions

I guess it means that Eclipse can't find the "http://www.springframework.org/schema/beans/spring-beans.xsd" file, that is at line 5. I've already checked it in the browser, the XSD exists.

If I try to use a specific version of the spring-beans.xsd, nothing changes.
I'm sure that I have internet connection as well.

Answer

I figured out that I downloaded the old springframework dependencies accidentally; e.g. instead of the org.springframework - core the simple springframework - core was used. That caused the problem.
