IllegalAccessError on Hibernate3 with Annotation initialization.

[michele]

Hi all!
I'm new on Spring2.
I have written a Web App using Spring1.2.8 and Hibernate3 with Annotation, and it works fine.
Now I want to make porting to Spring2.0-m5 but I failed due to an error got during the Hibernate3 initialization process.
Here after my application-context.xml file:

...
	<!-- ========================= DATASOURCES CONFIGURATION ======================== -->

	<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${database.driver}" />
		<property name="url" value="${database.url}" />
		<property name="username" value="${database.username}" />
		<property name="password" value="${database.password}" />
	</bean>

	<!-- ========================= HIBERNATE3 CONFIGURATION ======================== -->

	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 
		<property name="dataSource">
			<ref local="dataSource" />
		</property>
		<property name="configLocation" value="/WEB-INF/conf/hibernate/hibernate.cfg.xml"/>
	</bean>
	
	<!-- ========================= DAO CONFIGURATION ======================== -->

	<bean id="imageCollectionDAO" name="persistence::imageCollectionDAO"
		class="my.company.persistence.hibernate.HibernateImageCollectionDAO">
		<property name="sessionFactory">
			<ref local="sessionFactory" />
		</property>
	</bean>
...

but I took the following exception from Tomcat5:

...  INFO[ContainerBackgroundProcessor[StandardEngine[Catalina]]](SessionFactoryImpl.java:159) - building session factory

In my WEB-INF/lib I installed hibernate3.jar from Spring's libraries.

Can you help me?
I'm using:
-Spring 2.0m5
-Hibernate 3.1.3
-Hibernate Annotations 3.2RC1
-Tomcat 5.5
-Sun JVM 1.5.0_07

Thanks.

The latest hibernate uses ehcache 1.2 - you seem to be using an older version (1.1 maybe). Upgrade your ehcache library and report back if you still have problems.

Thank you for quickly reply!
I tried to use ehcache1.2 and still not worked,
but with ehcache1.2.1RC it worked.
By the way, I don't like to use a "RC" if it is possible I would like to avoid it.

Thus now I use the OpenSynphony Cache and it works very well (version 2.3.1).
The change was easy:

<hibernate-configuration>
	<session-factory>
		<property name="cache.provider_class">
			org.hibernate.cache.OSCacheProvider
		</property>
		<property name="hibernate.cglib.use_reflection_optimizer">
			true
		</property>
		<property name="hibernate.dialect">
			org.hibernate.dialect.InformixDialect
		</property>
		<mapping
			class="com.mycompany.persistence.vo.PimbatchWork" />
...
	</session-factory>
</hibernate-configuration>

The big change, AFAIK, in ehcache 1.2.x is the usage of an instance cache manager per session factory. You could downgrade hibernate to the stable version (3.1.3) which requires ehcache 1.x.
