Problem:  

You need to add ehcache*.jar(for example ehcache.2.7.4.jar) file into your classpath.

Solution:  

 Add the ehcache*.jar file to your class path or specify the maven dependency in pom.xml file.

<dependency>

   <groupId>net.sf.ehcache</groupId>

   <artifactId>ehcache</artifactId>

   <version>2.7.4</version>

</dependency>
