Simple ehcache project exception

Question

I'm currently converting some projects to maven and have been getting issues when the wars are started up. So I just created a very simple ehcache maven project and I'm getting a class loader type of issue. Here is my pom:

I litterally have a HelloWorld type of mvc setup without using ehcache in the springmvc part yet.

What am I missing? I'm assuming it is something simple, but my project looks like almost all hello world type of configs for a simple ehcache project.

Spring's EhCacheCacheManager class acts as a wrapper for an EhCache CacheManager instance. EhCacheManagerFactoryBean generates beans that are already wrapped in an EhCacheCacheManager object. So basically you're trying to wrap an object that's already wrapped. Instead just create one bean (using the factory) and you should get what you want:

<bean id="cacheManager" 
    class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
  <property name="configLocation" value="/WEB-INF/ehcache.xml" />
</bean>

If you need to reference the EhCache CacheManager instance, it is available on the getCacheManager() field of this cacheManager bean.
