Exception rising while running spring mvc-hibernate application

Question

I am getting the following exception

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 8 in XML document from ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 107; cvc-elt.1.a: Cannot find the declaration of element 'beans:beans'

My servlet-context.xml is as follows,

I suppose problem may be with the namespaces starting with https vs http. Try to use following namespace declarations in root element:

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