'EHcache with Spring Configruation + JdbcTemplate

I'm trying to implement cache with spring 3.0

Here is the code that is relevant to the integration:

<bean id="cacheManager" class="net.sf.ehcache.CacheManager">
    <constructor-arg index="0" type="java.net.URL" value="classpath:ehcache.xml"/>
</bean>

In application-context.xml file

I have a valid ehcache.xml file but it's never read since the application bombs before it gets there, the error I'm receiving is the following:

org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [net.sf.ehcache.CacheManager] for bean with name 'cacheManager' defined in ServletContext resource [/WEB-INF/spring/application-context.xml]; nested exception is java.lang.ClassNotFoundException: net.sf.ehcache.CacheManager

Does anyone have an idea of what I'm doing wrong?

Please add your ehcache jars to web-inf/lib directory.

If you are using Maven than add this to your pom.xml.

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>2.4.7</version>
</dependency>

If you start your project out of eclipse, check if you have added the ehcache library to the "Deployment Assembly" list.

Open your project's properties dialog -> "Deployment Assembly" and add the lib there.

Seems you should add ehcache-core jar to your classpath... Note to add the right version, though.

EDIT:

note that ehcache is used in the artifactId and not ehcache-core.

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>1.6.1</version>
</dependency>

After running mvn install again, make sure the right jar resides in your local repository and that it contains the right class.
