Hibernate Level 2 キャッシングに memcached を使用しようとしていますが、まだ機能していません。Tomcat を起動してアプリケーションを起動すると、次の例外 (java.lang.NoClassDefFoundError: org/hibernate/cache/TimestampsRegion) が発生します。
javax.servlet.ServletException: Servlet execution threw an exception

プロバイダーとして hibernate 4.1.7 で JPA を使用しています。hibernate L2 キャッシング用の persistence.xml プロパティは次のようになります。
<property name="hibernate.cache.provider_class" value="com.googlecode.hibernate.memcached.MemcachedCacheProvider" />
<property name="hibernate.cache.use_second_level_cache" value="true" />
<property name="hibernate.cache.region.factory_class" value="com.googlecode.hibernate.memcached.MemcachedRegionFactory"/>
<property name="hibernate.cache.use_query_cache" value="true" />
<property name="hibernate.Memcached.servers" value="localhost:11211"/>
<property name="hibernate.Memcached.cacheTimeSeconds" value="300"/>
hibernate および memcached に関連する次のバージョンの jar ファイルを使用しています。
memcached-2.3.1.jar hibernate-memcached-1.6.jar (com.googlecode.hibernate.memcached プロジェクトのソースからコンパイル) slf4j-1.5.0.jar slf4j-log4j12-1.5.0.jar
私はまだこの問題を回避できていません。皆さんからの助けは大歓迎です。
