org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: You must use a 3.0 schema with Spring Security 3.0.(2.0 or 3.1 versions are not valid) Please update your schema declarations to the 3.0.3 schema (spring-security-3.0.3.xsd).

Look like you have mis-match w.r.t your spring version.

For example in pom.xml or in your lib folder you have Spring 3.0 jar files whereas in spring-security.xml is having greater version of spring.

Solution is: Either updated spring version in as jar/pom.xml or change in spring-security.xml.
