@Cacheable with spring 3.1, Hibernate 4 and eh-cache

[spgmx]

Hi,

I want to use @cachable for my JPA2-Entities. I'm using spring 3.1 and Hibernate 4.1.6.Final and I want to use eh-cache as cache.

Although I followed the tips here:
http://www.javacraft.org/2012/03/mig...4-ehcache.html

I still get java.lang.NoClassDefFoundError: org/hibernate/cache/TimestampsRegion.

Has this something to do with spring 3.1?

Thank you.

P.S. EntityManager:

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
	    <property name="entityManagerFactory" ref="entityManagerFactory"/>
	</bean>
	<tx:annotation-driven transaction-manager="transactionManager" order="35"/>
	<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
	    <property name="persistenceUnitName" value="persistenceUnit"/>
	    <property name="dataSource" ref="dataSource"/>
	</bean>

persistence.xml:

No... And I also suggest you read the blog again, it explains what to do with this exception (you have to use the hibernate specific implementation). Either that or use a different cache factory for hibernate (check the hibernate or ehcache reference guide for more information).

I did use the hobernate-eh-cache version:

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-ehcache</artifactId>
<version>${hibernate.version}</version>
</dependency>
<!--
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache-core</artifactId>
<version>2.6.0</version>
</dependency>
-->

Please use [ code][/code ] tags when posting xml...

Check your dependencies and see if there isn't another one pulled in from somewhere. (Not sure if spring works with the ehcache version from hibernate).

As mentioned before also read the ehcache documentation.

I checked this serveral times, I have ehcache-core-2.4.3.jar which is a dependency of hibernate-ehcache.
I read the docs.
I think the problem is, that Spring 3.1 does not support jpa2 and hibernate 4.1 with eh-cache.

No it isn't... The error you get is an error from hibernate so your error is there... Using the same setup for a sample application so nothing is preventing you from using this combination.
