Spring uses its own mechanism to get the XSD in classpath library (runtime).
Uses following files
META-INF/spring.handlers
(to parse tag xml to object by an Handler)
example of spring-core-3.2.2.jar
http://www.springframework.org/schema/c=org.springframework.beans.factory.xml.SimpleConstructorNamespaceHandler
http://www.springframework.org/schema/p=org.springframework.beans.factory.xml.SimplePropertyNamespaceHandler
http://www.springframework.org/schema/util=org.springframework.beans.factory.xml.UtilNamespaceHandler
META-INF/spring.schemas
(to identify the correct xsd used)

The IDE want resolve the location of the XSD by schemaLocation, for this reason I suggest to remove XSD validation on your Eclipse.
Windows->Preferences->Validation-> "Suspend all validators"
