Thanks for your help. Do you have Spring 2.5.5 working on GlassFish V2
UR2 using the built in TopLink Essentials as a JPA provider? I tried
your suggestion and still get the EJBClassLoader exception. I noticed
that at some point I removed the PersistenceAnnotationBeanPostProc
line. I was hoping that was going to fix my problem. Here is what I
have now:

/WEB-INF/applicationContext.xml

<bean
class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
<tx:annotation-driven/>

<bean id="dataSource"
class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="jdbc/test"/>
</bean>

<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="jpaVendorAdapter">
        <bean
class="org.springframework.orm.jpa.vendor.TopLinkJpaVendorAdapter"/>
    </property>
    <property name="loadTimeWeaver">
      <bean
class="org.springframework.instrument.classloading.glassfish.GlassFishLoadTimeWeaver"/>
    </property>
</bean>

<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>


persistence.xml

<persistence-unit name="TestPU" transaction-type="RESOURCE_LOCAL">
      <provider>oracle.toplink.essentials.PersistenceProvider</provider>
      <class>com.example.dao.SystemSettingEntity</class>
</persistence-unit>


My JPA entities are inside the .war file. Where are yours? Is the
overall project inside an EAR?

I read that Hibernate doesn't need a load time weaver. I'm probably
going to try using Hibernate + Entity Manager as my JPA provider next.
I've spent 3 days on this so far, hopefully I will be successful before
the end of the day :)


Thanks,
Ryan
