Answer 1

Your XML header is referencing some invalid XSDs. Change this:

xsi:schemaLocation="
                    http://www.springframework.org/schema/beans
                    http://www.springframework.org/schema/beans/spring-beans-4.2.1.xsd
                    http://www.springframework.org/schema/security
                    http://www.springframework.org/schema/security/spring-security-3.2.4.xsd
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/context/spring-context-4.2.1.xsd"

to this:

xsi:schemaLocation="
                    http://www.springframework.org/schema/beans
                    http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
                    http://www.springframework.org/schema/security
                    http://www.springframework.org/schema/security/spring-security-3.2.xsd
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/context/spring-context-4.2.xsd"
