Getting "java.lang.ClassNotFoundException: org.hibernate.ejb.HibernatePersistence" even though class is there

[laredotornado]

Hi,

I'm using Maven 3.0.3 to try and deploy a Spring 3.1.1.RELEASE WAR to JBoss 7.1.1.Final.  I have configured my database access in my Spring application context like so …

[code]

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">

        <property name="packagesToScan" value="org.mainco.myco" />

        <property name="jpaVendorAdapter">

            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>

        </property>

        <property name="dataSource" ref="dataSource"/>

        <property name="jpaPropertyMap" ref="jpaPropertyMap" />

    </bean>

<util:map id="jpaPropertyMap">

  <entry key="show_sql" value="true" />

  <entry key="dialect" value="org.hibernate.dialect.MySQLDialect" />

  <entry key="hibernate.hbm2ddl.auto" value="validate" />

    <entry key="hibernate.cache.region.factory_class" value="org.hibernate.cache.ehcache.EhCacheRegionFactory"/>

    <entry key="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider"/>

    <entry key="hibernate.cache.use_second_level_cache" value="true" />

    <entry key="hibernate.cache.use_query_cache" value="false" />

    <entry key="hibernate.generate_statistics" value="false" />

</util:map>

<bean id="entityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">

  <property name="entityManagerFactory" ref="entityManagerFactory" />

</bean>

<!-- Application properties -->

<bean id="propertyConfigurer"

  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

  <property name="locations">

  <list>

                                        <value>classpath:application.properties</value>

  </list>

  </property>

  <property name="ignoreUnresolvablePlaceholders" value="true" />

</bean>

<jee:jndi-lookup jndi-name="java:jboss/datasources/MySqlDS" id="dataSource" expected-type="javax.sql.DataSource"/>

<tx:jta-transaction-manager />

[/code]

Since JBoss already comes with Hibernate, I'm not adding it to my WAR.  Bad sadly, I'm getting the below exception when I try and deploy ...

The class in question is here

$JBOSS_HOME/modules/org/hibernate/main/hibernate-entitymanager-4.0.1.Final.jar

Why doesn't Jboss find it and what else do I need to do to get this thing to deploy properly?  Thanks, - Dave

Hi,

configure your spring to use entity manager that app server provides and don't configure it manual (as you are doing now)

all jpa related configuration should go to persistence.xml and your spring config should just reference it.

read more about that:

http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/orm.html#orm-jpa

http://stackoverflow.com/questions/10392307/spring-spring-data-jpa-configuration

in short drop most of your configuration and it will work better

Spring 3.1 gives you the ability to configure JPA without using a persistence.xml file.  I like this because there is also an option (packagesToScan) that allows @Entitiy objects to be auto-detectected without having to explicitly list them. 

Given this, is it still possible to take advantage of the pre-installed JBoss Hibernate modules or do I need to figure out a solution where I include those on my own?

Thanks, -

I had this problem when trying to deploy a Spring application in JBoss AS 7.1.1 using the Snowdrop (Spring deployer) module. It turned out that Hibernate was not visible to Snowdrop. I added

    <module name="org.hibernate"/>

to the <dependencies> section of Snowdrop's module.xml, and that solved the problem for me.
