Answer

Make sure, following jar file included in your class path and lib folder.

spring-core-3.0.5.RELEASE.jar

enter image description here

if you are using maven, make sure you have included dependency for spring-core-3xxxxx.jar file

<dependency>
 <groupId>org.springframework</groupId>
 <artifactId>spring-core</artifactId>
 <version>${org.springframework.version}</version>
</dependency>

Note : Replace ${org.springframework.version} with version number.
