ehCache and Spring MVC Error with HIbernate

I am trying to get caching working on a Service layer method, but it still goes into it and calls the database. Is my setup wrong?

@Cacheable(cacheName="apiActivitiesCache", keyGenerator = @KeyGenerator (
            name = "ListCacheKeyGenerator",
            properties = {
                    @Property( name="useReflection", value="true" ),
                    @Property( name="checkforCycles", value="true" ),
                    @Property( name="includeMethod", value="false" )
            }
        )
    )
    public GetMemberActivitiesResponse getActivities(GetMemberActivitiesRequest request) {

servlet-context.xml

<ehcache:annotation-driven cache-manager="ehCacheManager" create-missing-caches="true"/>

    <ehcache:config cache-manager="ehCacheManager">
        <ehcache:evict-expired-elements interval="60" />
    </ehcache:config>

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

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
    <defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" />
    <cache name="apiActivitiesCache" eternal="false"  
        maxElementsInMemory="100" overflowToDisk="false" diskPersistent="false"
        timeToIdleSeconds="0" timeToLiveSeconds="300"
        memoryStoreEvictionPolicy="LRU" />
</ehcache>

Is getActivities defined by an interface? Spring uses interface based Java proxies for annotation wrappers so all annotated methods must be defined by an interface.

Are you using Ehcache Spring Annotations (http://groups.google.com/group/ehcache-spring-annotations)? This does not work with Hibernate.

I tried this with your exact configuration and it worked. Is your service class that has the getActivities method configured as a Spring bean?

Also, is the getActivities method being called by another class, or is it being called by another method in the same class?
